L6362A

L6362A - IO-Link PHY2 Transceiver | STMicroelectronics (Tape & Reel)

The STMicroelectronics L6362A is an IO-Link and SIO mode transceiver device compliant with the PHY2 (3-wire connection) specification, supporting COM1 (4.8 kbaud), COM2 (38.4 kbaud), and COM3 (230.4 kbaud) communication modes. It is housed in a 12-pin VFDFPN (3x3 mm) package with an exposed pad, designed for the industrial 24 V environment. An IO-Link transceiver is a specialized interface IC that sits between an industrial microcontroller and a 3-wire sensor or actuator cable, implementing the physical layer of the IO-Link single-drop digital communication protocol standardized under IEC 61131-9. The IO-Link protocol itself operates within the broader industrial sensor and actuator hierarchy (sensor front-end -> IO-Link PHY -> industrial fieldbus / PLC), and the L6362 belongs to the class of dedicated PHY2 transceivers that combine physical line driving, power supply conditioning, and protection in a single monolithic device. Key features include a 10 mA selectable linear regulator, 5 V and 3.3 V compatible I/Os, a 0.3 A output current intervention threshold, and a fully protected output stage that can be configured as high-side, low-side, or push-pull. The output driver can sink and source resistive, capacitive, and inductive loads typical of industrial sensor coils, and the device integrates reverse-polarity, overcurrent, and thermal protection. The selectable linear regulator provides a clean supply rail for an external sensor MCU or signal-conditioning block. Architecturally, the L6362A (the die family to which L6362A belongs) is a monolithic dual push-pull driver with on-chip diagnostics and a wake-up detector for SIO mode. The integrated 10 mA LDO simplifies the sensor-side supply tree, and the configurable output stage allows the same IC to drive either a PNP (high-side), NPN (low-side), or push-pull sensor, eliminating the need for external H-bridges. The exposed pad on the VFDFPN-12 package keeps junction temperature within safe limits during sustained output currents near the 0.3 A intervention threshold. Typical applications include industrial sensors, factory automation nodes, process-control transducers, and any IO-Link-compatible smart sensor or actuator port. The wide supply voltage tolerance and integrated protection make it well suited to harsh 24 V industrial environments with long cable runs. When designing with the L6362A, ensure adequate copper area under the exposed pad for thermal dissipation at sustained loads above 100 mA, and follow the datasheet recommended external MOSFET and TVS diode network for full IEC 61131-9 surge compliance. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.

L6364Q

L6364Q - Dual-Channel IO-Link Transceiver | STMicroelectronics

The STMicroelectronics L6364Q is a dual-channel IO-Link and SIO transceiver IC in a 20-pin QFN (4x4 mm) package, designed as the PHY interface between a microcontroller and the 24 V industrial sensor/actuator signaling cable. It embeds two physical channels with selectable 3.3 V / 5.0 V / high-side driver modes and integrates 50 mA 3.3 V and 5.0 V LDO regulators plus a DC-DC converter to supply the host MCU and external circuitry from the 24 V rail. As an IO-Link PHY, the L6364Q is a bridge transceiver (interface IC) positioned in the industrial-sensor signal chain: MCU -> IO-Link transceiver -> 24 V cable -> IO-Link master. It supports M-sequence handling, wake-up pulse generation, and SPI configuration from the host microcontroller so the device can be reused across discrete sensors, actuators, and binary (SIO) legacy modes. Key features include a wide 8 V to 36 V operating supply range compatible with industrial 24 V rails, integrated reverse-polarity and over-current protection on the high-side drivers, two independent CQ channels, dual LDO regulators (3.3 V and 5.0 V at 50 mA each) for host MCU supply, integrated DC-DC converter, and -40 C to +150 C extended industrial temperature range. The 20-pin QFN (4x4 mm) package minimizes PCB area for space-constrained sensor heads. Internally the L6364Q combines two C/Q output drivers with current limiting, two LDO regulators with power-good indication, a DC-DC controller for energy-efficient 24 V-to-low-voltage conversion, and an SPI interface for M-sequence parameterization. Compared with discrete IO-Link implementations, the L6364Q shrinks the BOM by replacing multiple protection devices, regulators, and the DC-DC passives with one qualified IC. Typical applications include industrial binary sensors and proximity switches, factory automation actuators with IO-Link connectivity, IO-Link sensor hubs and junction boxes, smart valve and valve-position feedback modules, robotics I/O modules, and process-control instrumentation. The wide input voltage range and integrated protection suit 24 V factory bus operation, while the dual channels enable single-chip two-port sensor nodes. When designing with this part, ensure that thermal management of the QFN exposed pad is adequate - the dual LDO currents plus DC-DC losses can produce 500 mW dissipation at full load. Use the SPI interface to switch from SIO mode to IO-Link mode dynamically without disturbing the in-progress IO-Link communication frame. This page synthesizes distributor pricing, real ST X-NUCLEO-IOD02A1 expansion-board integration notes, and practical design considerations that extend beyond the L6364 datasheet block diagram.

L6451013TR

L6451013TR - 28-Channel Inkjet Driver, 5.25 V | STMicroelectronics

The STMicroelectronics L6451013TR is a 28-channel inkjet print-head driver integrated circuit supplied in a 44-lead PLCC package. It operates from a nominal 5.25 V maximum supply rating, with distributor technical data also identifying a 4.75 V to 5.25 V supply range and a 0°C to 70°C commercial temperature grade. The device is designed for driving the high-voltage, high-current print-head loads found in inkjet printing equipment. An inkjet driver is a specialized interface IC that converts low-voltage logic commands into controlled high-voltage and high-current drive signals for piezoelectric inkjet nozzles. In the system hierarchy, this device is a printer-specific peripheral driver within the broader interface IC and power-driver categories. Its 28 output channels allow one controller to manage multiple print-head elements while reducing the number of discrete drivers required at the board level. The L6451013TR is listed as a 28-channel driver with a nominal peak output current limit of 2 A and a maximum supply voltage rating of 5.25 V. The 44-terminal PLCC package provides the mechanical footprint used in the original inkjet-printer controller boards. The commercial temperature range supports operation in controlled indoor printer and imaging environments, but the 0°C to 70°C limit is a key constraint for designs operating across wider industrial temperature ranges. Typical applications include inkjet print-head carriage electronics, multi-nozzle print-head assemblies, printer engine control boards, and specialized inkjet dispensing systems. Because it is a dedicated 28-channel print-head driver rather than a general-purpose logic buffer, its timing inputs, protection features, and pin functions are intended for a particular inkjet drive architecture. The principal design consideration is the relationship between the 2 A nominal peak output current rating, the inductive or capacitive load presented by the print head, and the protection network connected to each channel. PCB routing must minimize loop area in high-current drive paths, and unused or reserved outputs should be handled according to the manufacturer pin-description table. Production quantities should be confirmed before layout release because this is an older specialized printer-driver family with limited channel-count substitution. This page consolidates package, channel-count, supply, temperature, and output-current information into a structured engineering reference. It also distinguishes the documented L6451013TR ratings from specifications that must be taken directly from the manufacturer datasheet, including precise channel timing, dropout behavior, and protection thresholds.

L6783ATR

L6783ATR - Power Supply Op Amp | STMicroelectronics

The STMicroelectronics L6783ATR is a power-supply operational amplifier in the L6783 series, supplied in an 8-pin SOIC surface-mount package. It is intended for linear signal-conditioning and power-control circuits, with the exact input-voltage range, output-current capability, gain-bandwidth product, slew rate, and thermal limits specified by the manufacturer datasheet. The part is listed as active in the verified product references. An operational amplifier, commonly called an op amp, is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. The operational-amplifier category belongs to the broader linear-IC and amplifier-IC hierarchy, where precision gain, low distortion, stability, and output-drive capability determine suitability. A power-supply-oriented op amp is commonly selected when the signal or feedback node must operate from a supply rail higher than that of a conventional low-voltage amplifier. The L6783ATR's principal verified identifiers are its manufacturer, MPN, power-supply amplifier classification, active lifecycle status, and 8-pin SOIC package. Its “ATR” ordering suffix is associated with tape-and-reel production packaging, making it suitable for automated surface-mount assembly. Numerical electrical ratings are not reproduced on the supplied distributor search pages, so they are deliberately marked as data needed rather than inferred from unrelated amplifier families. A proper design review should begin with the STMicroelectronics L6783 datasheet, including its input common-mode range, output swing, supply-voltage limits, unity-gain stability, noise, offset voltage, slew rate, and recommended application circuit. These parameters determine whether the amplifier can directly drive the intended load or whether a buffer stage is required. The exposed thermal behavior of the SOIC package must also be checked against the dissipation expected at the selected supply voltage and output current. Typical design contexts include power-supply feedback and error-amplifier positions, current-control loops, analog signal conditioning, and instrumentation interfaces. In each case, the L6783ATR must operate inside its verified voltage and common-mode limits, maintain loop stability, and preserve signal integrity at the required bandwidth. Because those limits are absent from the supplied data, final suitability must be confirmed against the manufacturer documentation. For PCB implementation, place the device close to its feedback and compensation components, provide a low-impedance ground return, and decouple each supply pin with the capacitance and layout explicitly recommended by the manufacturer. Avoid adding external compensation unless the application circuit and stability analysis support it, since unnecessary components can alter bandwidth and transient response. This page consolidates the verified manufacturer identity, active status, distributor references, package information, ordering suffix, and source links while clearly separating unknown electrical data. It also provides replacement-search guidance and engineering checks without fabricating amplifier ratings or unsupported drop-in cross-references.

L9613B

L9613B - ISO 9141 Medium-Speed Data Interface | STMicroelectronics

The STMicroelectronics L9613B is a monolithic medium-speed data-interface IC containing standard ISO 9141-compatible interface functions. The manufacturer identifies the L9613 as a monolithic integrated circuit intended for automotive data-interface applications, while the L9613B ordering code is the subject of the supplied distributor and datasheet records. Its core function is to provide the physical-layer interface required by ISO 9141-compatible diagnostic communication systems. The supplied L9613 datasheet is 15 pages according to the verified document listing. An ISO 9141-compatible data interface is a wired automotive communication interface that connects an automotive diagnostic or test system to a vehicle network through defined K-line and related signal functions. Within the product hierarchy, the L9613B is a monolithic interface IC, a communication transceiver, and therefore a semiconductor-level realization of ISO 9141 physical-layer functions. This classification distinguishes it from general-purpose logic ICs, memory devices, microcontrollers, and analog power-management components. The verified manufacturer material confirms several important implementation details. The device includes standard ISO 9141-compatible interface functions. According to the manufacturer datasheet, the K, LO, and RX outputs have output-voltage behavior that varies with output current, including a transition related to RON multiplied by IOUT and a 2 × RON × IOUT plus UBE condition. The document also states that K, RX, and LI pins include protection against overvoltage, short circuits to ground or VS, and being driven beyond the supply rails. TX, RX, and LI receive comparable protection when internal pull-up behavior is considered. L9613B is intended for medium-speed data-interface systems using ISO 9141-compatible signaling. Its monolithic construction consolidates the required interface functions into one package, helping designers reduce the number of discrete interface elements around a vehicle diagnostic connector or tester. The documented output behavior makes the K, LO, and RX nodes important when designing cable termination, fault-recovery behavior, and logic-level compatibility. Exact electrical limits, timing values, supply range, and package dimensions must be taken from the manufacturer datasheet for production design. Typical use cases include automotive diagnostic testers, engine-control-unit service interfaces, vehicle workshop equipment, and ISO 9141-compatible electronic control modules. In these systems, the L9613B provides the physical-layer interface between a controller and an external diagnostic tool. Selection should account for the target vehicle network, cable length, bus topology, connector standard, protection requirements, and whether the interface must support legacy ISO 9141 rather than a newer protocol. The L9613B is not a general-purpose CAN transceiver and should not be treated as a substitute for CAN, LIN, or OBD-II protocol engines. For implementation, follow the manufacturer’s recommended input, output, decoupling, grounding, and protection arrangements. Verify every external resistor, capacitor, connector, and transient-protection device against the absolute maximum ratings and application diagrams in the L9613 datasheet. PCB signal integrity and automotive transient immunity are especially important because the interface connects directly to conductors entering a vehicle environment. Do not infer package pin numbers or package compatibility from distributor descriptions alone; use the official pin configuration before layout or substitution. This page consolidates the verified STMicroelectronics product page, manufacturer PDF, distributor listings, and targeted cross-reference results. It also separates confirmed ISO 9141 functionality from unverified quantities, making the documentation useful for preliminary design evaluation, sourcing, datasheet discovery, and drop-in-replacement investigation without presenting missing electrical or packaging data as established facts.

L9613B013TR

L9613B013TR - ISO 9141 Transceiver | STMicroelectronics

STMicroelectronics L9613B013TR is a monolithic ISO 9141-compatible automotive interface transceiver with one transmitter and one receiver, supplied in an 8-pin SOIC package. Its operating supply range is 4.8 V to 36 V, with transient operation up to 40 V. The interface is designed for K-line communication links in vehicle electronic control units and body electronics modules. An ISO 9141 interface transceiver is an integrated circuit that combines a line driver and line receiver with the electrical interface required by a K-line serial network. It belongs to the automotive interface IC category, where a controller uses a physical-layer transceiver to exchange diagnostic or application data with a vehicle bus. The L9613 provides the hardware layer between a microcontroller's serial I/O signals and the vehicle wiring harness. The L9613B013TR operates from a 4.8 V minimum supply and reaches a 36 V maximum supply, while tolerating transients to 40 V. Reverse-battery protection extends to VS values down to -24 V. These characteristics make the device suitable for automotive electrical environments where supply transients, load dumps, and incorrect battery polarity must be considered. A maximum signaling rate of 130 kbps is identified for the component. STMicroelectronics describes the L9613 as a monolithic integrated circuit containing standard ISO 9141-compatible interface functions. Integrating the transmitter and receiver reduces the number of external line-interface components required around a vehicle diagnostic controller. The 8-pin SOIC outline is compact enough for body-control and engine-control electronics while remaining compatible with standard small-outline surface-mount assembly methods. Typical applications include automotive diagnostic interfaces, engine control units, transmission controllers, body control modules, instrument clusters, immobilizers, and other embedded vehicle systems that communicate over a K-line physical layer. Using a dedicated transceiver helps isolate the controller from the wired diagnostic network and supports operation across the voltage range expected in automotive electrical systems. PCB implementation should follow the manufacturer's application diagram for decoupling, connector-side protection, and signal routing. Keep the transceiver close to the vehicle connector or bus interface, provide a stable local supply reference, and verify the connected ECU’s logic levels. The SOIC footprint leaves adequate routing space for bypassing and external protection components, but automotive transient and ground-loop requirements remain the dominant layout constraints. This product page combines the manufacturer interface description with package, voltage, speed, and sourcing details, then adds pin-assignment guidance, practical PCB considerations, application-specific selection advice, and a comparison of documented alternative variants. Engineers can use these notes to evaluate the L9613B013TR for an existing ISO 9141 circuit before requesting a quote and confirming supply availability.

L9615D

L9615D - 500 kbaud CAN Transceiver | STMicroelectronics

The STMicroelectronics L9615D is a bidirectional 1/1 CAN bus transceiver with signal-conditioning capability for CAN controllers, data rates up to 500 kbaud, and an 8-pin SOIC package. It supports both shielded and nonshielded CAN bus lines, generates differential transmitter outputs, and includes selectable slope control for 500 kbaud and 125 kbaud operation. Its CAN outputs are short-circuit protected to 36 V, while shutdown detection helps isolate faulted bus conditions. A CAN transceiver is an interface IC within the broader transceiver and physical-layer hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into a differential CANH/CANL bus output and converts the received differential bus state back into a controller-compatible RXD signal. The L9615 therefore belongs to the CAN interface and industrial communication networking category, where robust physical-layer behavior helps a controller communicate reliably over long, noisy wiring harnesses. The L9615D supports data rates up to 500 kbaud and meets ISO/DIS 11898 requirements stated in the manufacturer-related datasheet information. Two adjustable slope-control states accommodate 500 kbaud and 125 kbaud networks, allowing engineers to reduce radio-frequency interference and electromagnetic interference through controlled edge rates. Differential signaling provides common-mode rejection, bidirectional operation supports both transmit and receive paths, and 36 V short-circuit protection improves robustness against accidental bus faults. The L9615 uses slope control as an important signal-integrity feature rather than relying only on rise and fall-time behavior inherent to the output drivers. Slower transitions can reduce high-frequency emissions and ringing on long harnesses, while the faster setting supports the upper stated CAN data rate. The selected operating mode must therefore be matched to the configured network bit rate and the physical bus characteristics. The transceiver is designed for controller-centered architectures in which a CAN controller manages arbitration, frame handling, error detection, and bus arbitration. Typical uses include industrial automation equipment, automotive electronics, building automation, robotics, embedded control systems, and other CAN networks operating at 125 kbaud or 500 kbaud. In a typical design, the L9615D sits between a microcontroller or dedicated CAN controller and the CANH/CANL pair. External network termination, common-mode choke selection, transceiver supply decoupling, and protection-device coordination remain important board-level considerations. Designers should verify the absolute maximum ratings, recommended operating conditions, pin configuration, and application circuit in the official STMicroelectronics documentation before layout release. Because the supplied search data does not expose the complete official pin table or the package drawing, this page does not infer individual pin names. It also avoids claiming undocumented electrical thresholds. The verified starting price is US$0.5310 as of 2026-10-28. This page combines verified manufacturer descriptions, distributor package and availability information, ISO/DIS 11898 and 500 kbaud operating details, and engineering-focused selection guidance. It separates confirmed specifications from unavailable parameters and does not pad the alternatives list with reel-code variants or devices whose pin compatibility cannot be substantiated.

L9615D013TR

L9615D013TR - 500 kbaud CAN Transceiver | STMicroelectronics

The STMicroelectronics L9615D013TR is a single-channel CAN bus transceiver designed for bidirectional signal conditioning between a CAN controller and a twisted-pair CAN network. It supports data rates up to 500 kbaud from a 4.5 V to 5.5 V supply and is packaged in an 8-pin SOIC. The device provides one transmitter and one receiver, differential bus outputs, short-circuit protection, and shutdown detection. A CAN transceiver is an interface IC that converts logic-level transmit and receive signals into the differential voltages carried by a CAN bus. Its position in the hierarchy is CAN transceiver → CAN interface IC → interface integrated circuit → semiconductor. Unlike a physical-layer transformer or an isolated digital transceiver, the L9615 connects a controller directly to the bus while adding the driver, receiver, protection, and biasing functions required for reliable automotive or industrial communication. Key characteristics include operation up to 500 kbaud, conformance with ISO/DIS 11898, a 4.5 V to 5.5 V supply range, and short-circuit protection for bus outputs exposed to voltages up to 36 V. Slope control reduces radio-frequency interference during transitions. The half-rate CANH and CANL bus arrangement operates from a single transceiver perspective, while the package provides a compact surface-mount footprint for control modules and electronic control units. Internally, the transmitter converts a logic-level input into a dominant differential output across CANH and CANL. The receiver interprets the differential bus voltage and presents a logic-level output to the CAN controller. The transceiver also manages the recessive state, bus biasing, fault detection, and output-stage protection. Because the L9615 is a non-isolated device, its ground reference must be compatible with the controller and the rest of the CAN node. Typical applications include automotive body and comfort modules, industrial automation controllers, elevator systems, building-automation equipment, and embedded CAN gateways. It is particularly useful where a classic 500 kbaud CAN network is used instead of a higher-bandwidth CAN FD controller. The 8-SOIC package also makes the device suitable for designs that already use conventional surface-mount PCB assembly processes. When laying out the PCB, place the transceiver close to the bus connector and keep the CANH and CANL traces as a short, closely coupled pair. Provide the supply decoupling recommended in the manufacturer datasheet, and verify the controller transceiver logic levels and termination arrangement before layout release. The operating temperature range indicated for this ordering code is -40 °C to 110 °C.

It is supplied in an 8-pin SOIC package for surface-mount assembly in automotive diagnostic and communication interfaces. An automotive bus transceiver is an interface integrated circuit that combines bus-driver and receiver functions with the electrical protection and signal conditioning required to connect a host controller to a vehicle network. The L9637 belongs to the broader ISO 9141 interface transceiver hierarchy, where automotive diagnostics, K-line communication, and bidirectional serial links are the primary application domains. Key features include standard ISO 9141-compatible interface functions, bidirectional serial communication, reverse-battery protection, and a wide operating supply range. The monolithic design reduces the number of discrete components associated with a vehicle diagnostic interface. Its 8-pin SOIC format also supports compact surface-mount layouts and automated electronic assembly. The L9637 is intended for bidirectional communication between an automotive diagnostic tool, ECU, or other K-line interface and its associated controller. A 4.5 V minimum operating supply permits use in 5 V-class electronic systems, while operation up to 36 V provides headroom for automotive load-dump environments. The specified 40 V transient capability and -24 V reverse-supply protection are particularly important in vehicle electrical systems where wiring transients and accidental battery reversal can occur. Typical applications include ISO 9141 diagnostic interfaces, automotive ECU test equipment, bidirectional K-line links, vehicle communication modules, and service-bus diagnostic systems. The device is also suitable for industrial communication equipment that must reproduce an ISO 9141 bus interface. System-level suitability still depends on the exact bus waveform, bus speed, external resistors, connector protection, and ECU timing implemented around the transceiver. For PCB design, keep the bus connection and supply-return paths short, follow the manufacturer application schematic for external components, and place protection structures close to the vehicle connector. Designers should verify transient, ground-offset, and reverse-polarity conditions at the system level rather than relying only on the IC ratings. The available verified data does not provide the detailed pin table, temperature range, current limits, or timing characteristics. This page consolidates the verified STMicroelectronics product description, supply-protection limits, package information, ordering references, and distributor links into one engineering-oriented source. It also documents where pricing, pin-level, lifecycle, and drop-in replacement evidence remains unavailable, preventing unsupported claims from being presented as verified fact.

It is packaged in an 8-pin SOIC with a 0.154 inch, 3.90 mm body width. An ISO 9141 bus driver is a physical-layer interface IC that connects a low-voltage controller to a wired vehicle bus through a logic-level K line. This interface sits between an embedded controller or diagnostic tool and the vehicle wiring, combining bus-line drive, receive, protection, and standby behavior in one device. It belongs to the broader interface-IC and automotive-transceiver hierarchy. The L9637D013TR provides a typical supply current of 2.3 mA, a defined output-off state during undervoltage or supply interruption, and high input impedance when the supply or ground is unavailable. Its output current limiting is characterized by a typical value of 60 mA. Reverse-supply protection extends to -24 V, while transient operation reaches 40 V, making the interface appropriate for electrically demanding vehicle diagnostic networks. The device is used in ISO 9141 K-line diagnostic systems, automotive diagnostic testers, ECU test equipment, vehicle interface adapters, service-bus analyzers, and embedded diagnostic controllers. Its logic input and logic output arrangement allows a microcontroller UART to control and monitor communication with a vehicle ECU over the K line. When designing the circuit, protect the K-line connection against sustained faults and electrostatic discharge, place the bus-side interface components close to the connector, and verify that the external protection network does not distort the intended bus waveform. The 8-pin SOIC footprint is straightforward to route, but the connector-side transient path and ground return deserve particular attention in automotive harnesses. This page consolidates the device function, electrical limits, package details, drop-in alternatives, application guidance, and design considerations engineers need when selecting or integrating an ISO 9141 interface. It also distinguishes the target order code from related L9637 variants so engineers can verify packaging and temperature identifiers before placing a replacement on an existing PCB.

L9638D

L9638D - LIN Bus Transceiver, 20 kbaud, 26 V | STMicroelectronics

The STMicroelectronics L9638D is a single-wire LIN bus transceiver rated for data rates up to 20 kbaud, with an operating supply voltage range of 6 V to 26 V and 40 V transient withstand, supplied in an 8-pin SOIC (8SO) surface-mount package. It integrates the physical layer of the Local Interconnect Network, exposing a CMOS-compatible TXD input, an RXD output to the host microcontroller, a hardware enable input, and a single bidirectional LIN bus line. A LIN transceiver is a dedicated interface IC that connects a microcontroller's protocol handler to the physical bus wiring of a vehicle. In the hierarchy of electronics, a LIN transceiver belongs to the interface IC family, alongside CAN, RS-232 and RS-485 transceivers, and is a physical-layer building block for in-vehicle distributed power and control networks. LIN is a single-wire, low-cost, low-bitrate serial bus standardized for body electronics and comfort systems. Key features of the L9638D include conformance to the LIN specification revision 2.0, compatibility with standard ISO 9141 systems, operation down to 6 V for battery-connected 12 V systems, a very low typ. 10 microamp sleep quiescent current, wake-up through the LIN bus line, and an enable input driven directly from a microcontroller CMOS output. Technically the device is a monolithic integrated circuit that combines a bus driver and receiver with control logic for power-saving modes and external wake-up handling. Because the LIN bus is a single wire referenced to ground, the transceiver provides the dominant/ recessive level conversion, bus biasing and bus-recessive detection that the protocol handler requires, while the host microcontroller handles framing, checksums and timing. Typical applications include body control modules, door and tailgate modules, climate control units, ambient light and seat-occupancy sensor nodes, window lift controllers, and other LIN-attached automotive sub-systems where a low-cost single-wire network replaces point-to-point wiring. When designing with the L9638D, place the bus line connection and its pull-up resistor close to the device, keep the LIN trace away from switching nodes, and verify supply decoupling for the 6 V to 26 V operating range, including the 40 V transient condition present on automotive battery lines. The sleep current of 10 microamp typ. supports dark-current-sensitive parked vehicles.

It supports LIN transmission rates up to 20 kbaud over an operating power supply range of 6 V to 26 V, with transient tolerance to 40 V, and adds ISO 9141 compatibility for legacy systems. The device is supplied in an 8-SOIC (0.154 in / 3.90 mm width) surface-mount package. A LIN (Local Interconnect Network) transceiver is a physical-layer interface IC that sits between a microcontroller's protocol handler and the physical single-wire vehicle bus. In the hierarchy of semiconductor devices, a LIN transceiver is an automotive bus transceiver, which is a line driver and receiver, which is an interface IC, which is an integrated circuit. LIN networks use a single wire plus a shared ground return, which keeps harness weight low compared with CAN or RS-485 multi-wire buses and makes the topology ideal for doors, seats, mirrors, climate control units and body control modules. Key features of the L9638D013TR include transmission rate up to 20 kbaud, a wide 6 V to 26 V operating supply range with 40 V transient withstand, low sleep-mode quiescent current of typically 10 uA, and three independent wake-up paths: wake-up through the LIN bus, an Enable input that is CMOS compatible from a microcontroller, and an edge-driven wake-up input. Transmit and receive delays are specified at 4000 ns and 6000 ns respectively, and the wide input and output ranges support both ISO 9141 and LIN signalling. Architecturally the L9638 combines a LIN output stage with a level-shifted receiver and an integrated voltage reference, plus internal protection structures for reverse battery, load dump and ESD events on the bus line. Because the transceiver dominates the quiescent budget of a body module in sleep, the 10 uA typical sleep current is what allows long-term parking drain budgets to be met, while the CMOS-compatible enable pin lets the host MCU gate the device directly. Typical applications include LIN sub-bus nodes in automotive body control modules, seat and door modules, climate control panels, mirror actuators, ambient light and rain sensors, window lift controllers, and any ECU that must wake from a low-current sleep state and rejoin a 20 kbaud LIN network. The ISO 9141 compatibility also makes it useful in mixed legacy diagnostic architectures. When designing around this device, place the bus-line protection and pull-up network close to the LIN pin, keep the wake-up and enable traces away from the high-voltage transients on the supply pins, and verify that the host microcontroller's TX/RX levels match the CMOS-compatible Enable and wake-up input thresholds. The 40 V transient rating gives headroom on 12 V and 24 V battery systems, but the device is not a substitute for a dedicated LIN bus protection diode network on severe-load networks.

It supports Mode 1 and Mode 2 PSI5 system architectures, allowing a host microcontroller to configure the interface for the selected sensor-network topology. A PSI5 transceiver is an automotive interface IC that connects a microcontroller to sensors using the PSI5 physical layer. In the broader semiconductor hierarchy, it belongs to the transceiver and interface-controller class, then to the interface IC category, and ultimately to the wider automotive analog and mixed-signal semiconductor market. Its primary function is to support communication between a vehicle's electronic control unit and peripheral sensors. The L9663-TR-1 includes an integrated frequency-locked loop, or FLL, that can track an external clock reference and provide a clock with ±1% accuracy. This feature is significant because PSI5 sensor timing and synchronous data transfer depend on a stable reference. The device also supports SPI communication for configuration and control by the host microcontroller. Its 4.8 V to 35 V operating supply range accommodates low-voltage sensor networks and higher-voltage automotive electrical environments. The manufacturer datasheet identifies two supported PSI5 communication architectures. Mode 1 and Mode 2 differ in how the transceiver communicates with the microcontroller, and the correct IC configuration must be selected for the implemented architecture. This makes software initialization and application-circuit design central to successful deployment. The integrated FLL and external clock-reference path provide synchronization benefits when the vehicle network requires an accurate common timing source. Typical applications include automotive radar and camera sensor interfaces, vehicle body and chassis electronics, engine or powertrain control modules, and other electronic control units that connect sensors through PSI5. In such systems, the L9663-TR-1 acts as the physical-layer interface between the MCU and remote sensors while handling clock tracking, serial configuration, and sensor-network communication. Designers should verify the exact operating mode, reference-clock configuration, external components, and electrical limits against the manufacturer datasheet before layout release. The 32-pin TQFP requires careful power and ground distribution, while automotive applications require attention to transient immunity, EMC behavior, and the system-level qualifications of the complete electronic control unit rather than the IC in isolation. This page consolidates verified manufacturer and distributor information, distinguishes confirmed L9663 family ordering variants, maps the device to automotive PSI5 applications, and clearly identifies specifications that still require confirmation from the official datasheet. That separation between verified data and unresolved engineering details helps designers make sourcing decisions without treating distributor metadata as a substitute for the datasheet.

L9679B

L9679B - Automotive Battery Cut-Off and Airbag IC | STMicroelectronics

STMicroelectronics L9679B is an automotive battery cut-off and airbag-system expansion interface IC packaged in an LQFP-100 (14x14x1.4 mm) package. The supplied distributor information identifies it as a specialized interface and power-management SPS ASSP, while the available datasheet indexing describes it as an automotive battery cut-off circuit and airbag system expansion IC. Its 100-pin package provides the external connections required to integrate battery monitoring, load-control, and restraint-system interface functions within a vehicle electronic control unit. An automotive battery cut-off and airbag expansion IC is a specialized interface device within the broader hierarchy of automotive interface IC, system-specific peripheral, power-management IC, and semiconductor. These devices connect battery and restraint-system circuits to a larger microcontroller or vehicle network while providing the electrical functions needed for controlled switching, monitoring, diagnostics, and expansion of airbag-system connections. Their design emphasis is integration within demanding vehicle electronics rather than general-purpose signal processing.

It is supplied in a 100-lead LQFP package, giving the design a substantial pin count for multiple automotive circuit interfaces. The available source data does not provide verified operating-voltage, output-current, logic-threshold, diagnostic, or switching-time figures, so those technical values must be confirmed directly against the manufacturer datasheet before design release. Automotive battery management is a natural use for this device because the L9679B is specifically described as an automotive battery cut-off circuit. Its integration can reduce the number of discrete connections and interface functions otherwise required around the battery-monitoring and load-control sections of a vehicle ECU. Engineers should still evaluate the supported battery chemistry, operating range, quiescent load, and protection behavior against their exact vehicle platform before assigning the IC. The airbag-system expansion function is also explicitly identified in the available L9679E family description. In a restraint-system controller or expansion interface, the L9679B can support additional squib-driver or deployment-loop connections while remaining under the control of the vehicle's safety controller. Because deployment behavior is safety-critical, the complete manufacturer application information, fault-response requirements, and diagnostic strategy must govern the implementation. The main design consideration is verification depth. Although the LQFP-100 package and automotive interface role are established by the supplied listings, detailed pin assignment, thermal limits, electrical characteristics, and component revisions are not included in the retrieved data. Do not infer them from a similarly named L9679-family device without confirming the exact suffix and revision against the STMicroelectronics datasheet and qualification documentation. This product record combines verified distributor pricing, package identification, source links, and application-oriented engineering guidance. It also distinguishes documented facts from unavailable parameters, reducing the risk of treating generic family descriptions as guaranteed L9679B electrical limits.

In the broader electronics hierarchy, the L9680 belongs to the interface-IC class, automotive electronics, and power-management-related safety systems. Its role differs from a general-purpose MCU because it is designed around the functional safety, diagnostic, and communication requirements of airbag and integrated vehicle-safety architectures. The verified information confirms the L9680's application positioning as an advanced airbag solution, its support for mature airbag markets and cut-off-battery integrated safety systems, and its family compatibility with the L9678 and L9679 devices. The family-compatible architecture can help automotive designers reuse application knowledge across related STMicroelectronics safety products, provided that the exact device variant, diagnostics, external circuitry, and safety requirements are verified before substitution. The L9680TR uses a 100-TQFP, 14 x 14 mm package according to the distributor listing, with a reel packaging format and SMT mounting style. This package provides a high pin count for power, ground, communication, sensor, and diagnostic connections, but it also demands careful PCB escape routing and adequate thermal design around the exposed pad. The manufacturer data identifies the part as an automotive product; detailed electrical ratings, operating temperature limits, supply voltages, SPI timing, internal diagnostics, and safety-certification parameters are not included in the supplied verified data. Typical applications include conventional automotive passenger airbag controllers, cut-off-battery integrated safety systems, and vehicle safety platforms that require an active wheel-speed-sensor interface. It is also relevant to mid- and high-end airbag systems where robust sensing, communications, and deployment-control integration are required. Because an airbag IC is safety-critical, system qualification should include review of the current STMicroelectronics datasheet, reference design, diagnostic requirements, external component values, and applicable automotive quality procedures. For a new design, preserve the L9680TR footprint and verify every exposed-pad connection, supply rail, ground reference, sensor input, and SPI signal against the current datasheet. Do not treat L9678P, L9679P, or L9679BATR as unconditional replacements: the verified cross-reference data establishes family compatibility and a common 100-TQFP format for some variants, but it does not provide a complete pin-to-pin and functional-equivalence matrix.

Typical applications include automotive electronic control units, body-control modules, relay and switch monitoring circuits, and other 12 V or 24 V vehicle systems that must distinguish closed contacts connected to ground or battery. System designers must also account for the 40 V transient limit, input-clamp behavior, and the effects of wiring harness transients and contact bounce. A key design consideration is that the L9705D is intended for contact monitoring rather than general-purpose high-voltage digital input sensing. PCB routing should preserve the intended contact-current paths, while the external network and supply decoupling must be designed for the automotive electrical environment. The published contact resistance comparison function should be evaluated against the resistance range of the actual switch or relay being monitored. This product page consolidates verified manufacturer and distributor information, package details, operating limits, sourcing links, and engineering guidance. It also distinguishes documented specifications from unavailable data and explains why a defensible pin-to-pin replacement cannot be recommended without verified cross-reference evidence.

L9864D/XT

L9864D/XT ABS Diagnostic Interface IC | STMicroelectronics

The STMicroelectronics L9864D/XT is a specialized wireless-interface integrated circuit identified by distributor listings as an ABS diagnostic interface device. The verified product information confirms the manufacturer, MPN, ABS interface function, tube packaging, lead-free status, and availability references, but it does not provide the electrical limits, pin configuration, clock characteristics, diagnostic thresholds, or package dimensions required for a complete engineering specification. An ABS diagnostic interface IC is a semiconductor interface device used to connect automotive or equipment-level diagnostic functions to a larger electronic control architecture. In the broader hierarchy, this component belongs to the wireless-interface IC category and ultimately to the integrated-circuit and semiconductor ecosystems. The L9864D/XT is intended for applications where an ABS-related diagnostic signal must be conditioned, monitored, or conveyed within a vehicle communication system. Its exact internal architecture and supported vehicle-network protocol are not stated in the supplied sources. The verified distributor listings describe the L9864D/XT as an ABS diagnostic interface and classify it under RF wireless miscellaneous interfaces. The part is associated with tube packaging according to the DigChip datasheet listing, and the XAIPART site-MPN list includes related STMicroelectronics interface products such as L9678P, L9679PTR, and L6362A. However, the supplied cross-reference results do not establish that any of those related devices are electrically or pin-for-pin interchangeable with the L9864D/XT. The L9864D/XT should therefore be selected based on confirmed manufacturer documentation, exact package drawing, pinout, electrical characteristics, and vehicle or equipment compatibility. Designers should not infer interchangeability from the shared ABS or interface designation alone. The verified distributor pages identify the part as a wireless interface, while the Heisener listing describes it as an ABS telecom interface; these descriptions support the functional classification but do not establish performance ratings. Typical implementation involves connecting the device to a diagnostic bus and a host or controller, then validating the signal behavior across power, reset, communication, and fault conditions. Because the supplied data does not include supply voltage, interface timing, ESD rating, operating temperature, or automotive qualification information, those values require confirmation from the manufacturer datasheet before schematic release or production procurement. A critical sourcing check is to compare the exact order code, package marking, tube quantity, and pin arrangement. The slash in L9864D/XT identifies the distributor-visible orderable variant, while the suffix and package arrangement must be confirmed against the STMicroelectronics product documentation. This page combines verified distributor information, commercial availability references, technical-data gaps, and drop-in-replacement cautions so engineers can make an informed sourcing decision without confusing related interface ICs with guaranteed replacements.

Key features of the L9955 include a low quiescent current of typically 0.4 mA per amplifier, a unity-gain bandwidth of 1 MHz, and a slew rate of 0.5 V/µs. It also offers a wide common-mode input voltage range that includes ground, making it suitable for single-supply operation. The output stage can swing close to the supply rails, maximizing dynamic range in low-voltage systems. These specifications make it an excellent choice for battery monitoring, sensor interfaces, and portable instrumentation. The L9955 uses a bipolar transistor architecture with internal frequency compensation, ensuring stability without external components. The input stage is designed for low offset voltage and low input bias current, which is essential for precision DC applications. The output stage is a class-AB push-pull configuration, providing low crossover distortion and the ability to drive capacitive loads up to 100 pF without oscillation. Typical applications include portable medical devices, battery-powered data loggers, and industrial process control loops. In a battery monitoring circuit, the L9955 can amplify the small voltage drop across a sense resistor, with its low quiescent current extending battery life. For sensor interfaces, the wide input range and rail-to-rail output allow direct connection to ADCs without additional level shifting. When designing with the L9955, ensure proper decoupling of the power supply pins with 0.1 µF ceramic capacitors placed close to the IC. The input common-mode range extends to ground, but for best performance, keep inputs within the specified range. The output can drive loads down to 2 kΩ, but for heavier loads, consider using a buffer stage to maintain linearity.
