TLE8457CLEXUMA1

TLE8457CLEXUMA1 - 5V LIN Transceiver with 70mA LDO

Infineon Technologies TLE8457CLEXUMA1 is an automotive LIN transceiver with an integrated 5 V low-dropout regulator, 70 mA regulator output capability, and a 20 kBd LIN data rate. It is supplied in an 8-pin PG-TSON-8-1 surface-mount package with an exposed pad and is offered in a tape-and-reel ordering configuration. The integrated regulator is designed to supply a microcontroller and associated peripherals from the vehicle LIN network. A LIN transceiver is an interface integrated circuit that connects a microcontroller to a Local Interconnect Network bus. LIN is a low-cost, single-wire automotive communication network used for distributed vehicle functions such as body electronics, climate controls, lighting modules, seat controls, and door modules. A LIN transceiver combines the physical-layer driver and receiver with logic interfacing, while an integrated LDO allows the device to establish a local regulated supply for nearby control electronics. The principal characteristics of the TLE8457CLEXUMA1 are its integrated 5 V regulator, 70 mA regulator output, 20 kBd bus speed, and 20 µA standby current. Combining the LIN interface and regulator in one package reduces the number of components required beside a microcontroller. This integration can simplify PCB routing while reducing the area required for a basic LIN-connected control node. The exposed-pad TSON package also provides a defined thermal path from the device to the PCB copper area. The device is identified as an automotive-grade LIN interface solution with AEC-Q100 qualification. Its 20 kBd communication rate is appropriate for LIN networks that use the standardized low-speed automotive communication profile. The 5 V regulator output supplies the local node electronics, while the LIN interface handles communication between the node and the vehicle bus. The 70 mA output capability should be evaluated against the combined load current of the microcontroller, pull-up circuitry, sensors, and attached peripherals. Typical uses include LIN-controlled body modules, automotive switch and relay interfaces, climate-control panel endpoints, lighting controllers, seat and door electronics, and small sensor nodes. In these systems, the microcontroller handles application logic, the TLE8457CLEXUMA1 handles the physical LIN connection, and the integrated regulator powers suitable low-current circuitry. System partitioning must ensure that the regulator load remains within its specified capability and that the automotive supply network meets the device requirements shown in the manufacturer documentation. When laying out the PCB, use the exposed pad as part of the thermal and ground structure and follow the manufacturer’s land-pattern, pin-assignment, and assembly guidance. Place the decoupling capacitors close to their associated supply pins with short return paths. The LIN bus connection also needs careful review of transceiver placement, trace geometry, grounding, and protection strategy so that switching events and external wiring do not degrade communication reliability. This product page organizes the confirmed device functions, automotive interface role, package information, and engineering use cases into one reference. It also distinguishes verified drop-in replacements from functional alternatives so that PCB reuse decisions are based on package, pin, and parameter compatibility rather than only on the shared LIN interface category.

It supplies a microcontroller and associated peripherals with up to 70 mA while providing the physical-layer interface for LIN bus communication. A LIN transceiver, also called a LIN interface or LIN physical-layer device, connects a low-speed serial network controller to a vehicle communication bus. In the broader hierarchy, it belongs to the LIN interface transceiver class, interface IC category, and automotive semiconductor ecosystem. Integrating the voltage regulator with the bus interface reduces the number of external power components needed in compact automotive modules while preserving a stable 5 V supply for the local controller and peripherals. The TLE8457CSJ family combines a LIN transmitter, LIN receiver, and low-dropout regulator in one integrated circuit. Its 20 kbit/s LIN data rate suits body electronics and comfort systems, while the 70 mA regulator output is intended for local microcontroller support rather than high-current loads. A low standby current of 20 µA is specified for the device family, helping reduce quiescent consumption when an automotive module enters a low-power state. The PG-DSO-8 package is designed for surface-mount assembly and is associated with an automotive qualification grade of AEC-Q100. The device is identified with a one-transmitter, one-receiver configuration, and its RoHS 3 compliant and REACH unaffected declarations support use in modern automotive electronics supply chains. Moisture sensitivity is listed as MSL 3 for 168 hours, making controlled handling and reflow-profile management important during manufacturing. Typical uses include LIN-controlled door modules, seat and climate-control electronics, body-control interfaces, sensor nodes, and compact automotive peripheral units. In each case, the transceiver handles the physical bus levels while the integrated 5 V regulator powers the local processing circuitry. Designers should also check the LIN bus topology, termination, transceiver enable behavior, wake-up requirements, and available regulator current before assigning a supply load to the internal LDO. For a new PCB, follow the manufacturer pin-description table for signal assignment and place the input, output, and bus-decoupling components close to their associated pins. Keep the LIN bus routing away from sensitive analog and high-speed digital paths, and confirm that the chosen connector, ESD strategy, and grounding arrangement preserve the integrity of the physical layer. This page consolidates the verified electrical ratings, package information, automotive compliance details, procurement workflow, and engineering guidance needed to evaluate the TLE8457CSJXUMA1 for a LIN-connected automotive module.

TLE8457DLEXUMA1 - 3.3V LIN Transceiver | Infineon

Infineon Technologies TLE8457DLEXUMA1 is a single-channel LIN transceiver with an integrated 3.3 V voltage regulator, 20 kBd LIN communication, and an integrated 70 mA supply for a microcontroller and peripherals. The device is packaged in an 8-pin PG-TDSON-8-1 automotive surface-mount package and is identified as AEC-Q100 qualified. Its LIN interface supports bidirectional communication compliant with LIN specification 2.2A and SAE J2602. A LIN transceiver, also called a Local Interconnect Network transceiver, connects a low-cost microcontroller to a vehicle network that uses one signal wire. The communication architecture is based on a master node and one or more slave nodes. Because LIN is designed for slow, short-range vehicle sub-networks, its physical-layer transceiver combines a regulated supply, bus interface, logic-level data interface, and fault-recovery functions in one device. The TLE8457DLEXUMA1 uses a stable 3.3 V regulator to supply a microcontroller and attached peripherals up to 70 mA. This integration can reduce the number of discrete supply components and simplify PCB allocation in compact body, comfort, or sensor nodes. The 20 kBd bus rate is suitable for LIN 2.2A applications in which nodes exchange diagnostic or control information over low-speed vehicle networks. The LIN physical layer provides bidirectional communication and is compliant with LIN specification 2.2A and SAE J2602. Its integrated regulator includes undervoltage-reset protection for the supplied microcontroller and peripherals. Exact input-voltage limits, regulator dropout behavior, bus thresholds, protection details, and timing limits should be taken directly from the Infineon TLE8457C/TLE8457D manufacturer datasheet when designing the power and interface networks. Typical uses include LIN gateway modules, door and window control units, seat-control modules, climate-control peripherals, ambient-light sensors, and other distributed vehicle nodes. The integrated 3.3 V supply is particularly useful when the host controller and its immediate peripherals operate from a common low-voltage rail while also communicating through the LIN bus. Layout the LIN bus connection for automotive transient immunity, keep the transceiver close to its connector, and provide the decoupling and protection network recommended by the manufacturer. Confirm the package land pattern and exposed-pad thermal requirements against the PG-TDSON-8-1 drawing before release because exposed-pad soldering and copper treatment strongly affect assembly yield and thermal performance. This product page organizes the manufacturer specifications, interface requirements, application context, and design constraints for engineers evaluating the TLE8457DLEXUMA1. It also distinguishes verified drop-in alternatives from merely similar automotive LIN devices, helping prevent footprint or function mismatches during replacement planning.

TLE8458GXUMA1

TLE8458GXUMA1 - Integrated 5V LIN Transceiver | Infineon

The Infineon TLE8458GXUMA1 is an automotive LIN transceiver with an integrated low-dropout 5 V voltage regulator, combining a 1/1 LIN bus interface and a single fixed-output regulator in an 8-pin DSO surface-mount package. The device is intended to supply a LIN-connected microcontroller while operating a LIN bus from the same automotive power architecture. A LIN transceiver is a physical-layer interface IC for the LIN bus, a low-cost single-wire automotive communication network. Its hierarchy runs from LIN transceiver to vehicle-network transceiver, automotive interface IC, and power-management semiconductor. Integrating the regulator eliminates a separate 5 V supply circuit for compatible microcontroller domains and reduces PCB area, component count, and the number of power-supply interconnects. Verified distributor data identifies the TLE8458GXUMA1 as a fixed positive, single-output LDO regulator with a minimum input voltage of 5.5 V, 2% maximum voltage tolerance, eight gull-wing terminals, and a 10.4 kBd LIN interface rate. The same 5.5 V minimum input condition permits the regulator and LIN transceiver to operate from a common automotive supply while providing a regulated 5 V rail to the attached microcontroller. The LIN side provides one driver and one receiver for a typical LIN master or slave node. It supports nodes requiring combined communication and regulated supply, such as door modules, body controllers, seat controllers, climate-control panels, lighting modules, and compact automotive sensor nodes. Because LIN uses a single-wire bus, the interface reduces wiring cost compared with a multiwire automotive network while retaining a defined physical-layer interface for distributed vehicle electronics. The 8-pin DSO package is surface mount and compact, but the exposed environmental requirements of automotive electronics make PCB planning important. Route the LIN connection away from sensitive analog and communication nodes, keep the regulator output close to its decoupling capacitor, and use a return path that avoids high-current switching currents. Verify absolute maximum voltages, output load conditions, bus termination strategy, and supply transient behavior against the manufacturer datasheet before releasing a production design. Pricing, exact absolute maximum ratings, temperature limits, output-current capability, and a complete pin map were not supplied in the verified data and therefore remain marked as data needed rather than inferred.

TLE9250XSJXUMA1

TLE9250XSJXUMA1 - 5Mbps CAN FD Transceiver PG-DSO-8 | Infineon

The Infineon TLE9250XSJXUMA1 is a high-speed CAN FD transceiver supporting data rates up to 5 Mbit/s, supplied in an 8-pin PG-DSO-8 package with operating voltage range 4.5 V to 5.5 V and an automotive temperature grade of -40 C to +150 C. It implements the physical layer according to ISO 11898-2 (2016) and is qualified to AEC-Q100 for automotive use, making it a drop-in interface between a microcontroller's CAN protocol controller and the differential bus wiring. The 5 Mbit/s CAN FD capability is essential for modern automotive networks carrying larger payloads such as ADAS sensor data, diagnostic telemetry, and gateway traffic. A CAN transceiver is a physical-layer interface IC that translates a microcontroller's digital CAN TXD/RXD logic-level signals into the differential CANH/CANL bus signaling required by the ISO 11898-2 standard. It also provides bus fault tolerance, dominant time-out, and ESD protection on the bus pins. In the broader hierarchy, the TLE9250XSJ sits between the protocol controller (an MCU or standalone CAN controller) and the wiring harness, protecting the controller from bus transients while driving the bus to the required differential voltage levels. Key features include very low electromagnetic emission (low EME) optimized for automotive EMI requirements, a low-power mode with remote wake-up via CAN bus activity, integrated bus pin ESD protection, dominant time-out for TXD stuck-dominant fault handling, and overtemperature shutdown. These features minimize external component count and simplify compliance with OEM EMC standards. The device also supports a 3.3 V compatible logic interface on TXD/RXD/EN/NSTB pins, allowing direct connection to modern low-voltage microcontrollers without level shifters. From an architecture standpoint, the TLE9250XSJ uses a fully integrated differential driver and receiver with separate supply pins for the digital interface (VDD, 3.3 V to 5 V) and the bus driver (VSUP, battery). This split-rail approach allows the bus to remain powered while the MCU side is off, supporting partial networking and low quiescent current in sleep mode. The internal slope control reduces radiated emissions at high bus speeds, eliminating the need for external common-mode chokes in most applications. Typical applications include automotive body control modules (BCM), gateway ECUs connecting multiple CAN sub-networks, electric vehicle battery management systems (BMS), ADAS sensor fusion nodes, and industrial CAN FD networks. Its wide supply range and automotive-grade qualification make it equally suitable for 12 V and 24 V truck/commercial-vehicle platforms. A key design consideration is the use of a common-mode choke and split bus termination (60 ohm between CANH and CANL plus two 30 ohm to ground) for optimum signal integrity at 5 Mbit/s. The non-sleep current is typically below 10 uA with remote wake-up enabled, making the part well-suited for partial networking where ECUs may be selectively powered down.

TLE9351VSJXTMA1 - 5Mbps CAN FD Transceiver PG-DSO-8 | Infineon

The Infineon TLE9351VSJXTMA1 is a high-speed CAN FD transceiver supporting ISO 11898-2, SAE J2284, and CAN FD up to 5 MBit/s, housed in an 8-pin PG-DSO-8 package. It operates from a 3.3V or 5V supply and includes a standby mode for low quiescent current, targeting automotive in-vehicle networks where reliable bus communication is mandatory. The part is AEC-Q100 qualified, confirming its suitability for harsh automotive electrical environments including load-dump, jump-start, and reverse-battery transients. A CAN transceiver (Controller Area Network transceiver) is a physical-layer IC that sits between a microcontroller's CAN protocol controller and the differential CAN bus. It converts single-ended TX/RX logic levels into the differential dominant/recessive bus states defined by ISO 11898-2 and rejects common-mode noise through high common-mode rejection. In the broader system hierarchy it belongs to: transceiver -> physical-layer interface -> in-vehicle networking IC -> automotive power management and communication IC -> semiconductor. CAN FD (Flexible Data-rate) extends classic CAN by increasing the data-phase bit rate while keeping the arbitration phase at the legacy bit rate, enabling larger payloads and faster ECU-to-ECU throughput. Key features include bus fault protection up to ±42V, thermal shutdown, undervoltage detection on VCC, and a low-power standby mode with bus wake-up capability. The receiver exhibits high common-mode immunity for reliable operation in noisy automotive harnesses, and the transmitter delivers a tightly controlled differential output with slope control to limit EMI. The PG-DSO-8 footprint is industry-standard for 8-pin CAN transceivers, simplifying PCB layout migration between competing solutions. Typical applications include body control modules, gateway ECUs, powertrain ECUs (where CAN FD is increasingly required), battery management system CAN interfaces, and ADAS sensor clusters. The standby mode enables quiescent current budgets in the microamp range, supporting always-on CAN networks that must wake the ECU upon bus activity. When designing with this part, place the VCC decoupling capacitor within 2mm of the VCC pin and route the CANH/CANL traces as a 100-ohm-impedance differential pair with ground stitching vias. Use a TVS diode such as NUP2105L on the bus pins to survive ISO 7637-2 pulse transients not covered by the IC's internal ±42V protection. The SPLIT pin, if used, requires a capacitor to ground.

TLE9877QXA40 - BLDC Motor SoC, 40MHz Cortex-M3, 64KB Flash | Infineon

The Infineon TLE9877QXA40 is a single-chip 3-phase brushless DC (BLDC) motor driver in the MOTIX™ TLE987x family, integrating an Arm® Cortex®-M3 core at 40 MHz, 64 KB of embedded Flash with ECC, 6 KB RAM, a LIN transceiver, and three NFET gate drivers in a VQFN-48-31 package with 0.5 mm pitch. The part operates from 5.5 V to 28 V supply and provides integrated low-dropout regulators for internal and external power rails. A built-in charge pump supports 100% PWM duty-cycle operation of the high-side NFETs, which is critical for slow-speed or fully-energized phases of BLDC commutation. A System-on-Chip (SoC) in this context is a single silicon device that combines a microcontroller, communication transceivers, power-management blocks, and analog/driver peripherals. In the broader taxonomy it sits below Microcontroller Unit (MCU) and above a discrete motor-control board; the TLE9877QXA40 specifically belongs to the Embedded Power IC family aimed at fractional-horsepower automotive mechatronics. This integration collapses what used to be a four-chip solution (MCU + LIN transceiver + 3-phase pre-driver + LDO) into one AEC-Q100-qualified die, reducing PCB area and BOM count in space-constrained modules such as water pumps, fans, and HVAC blowers. Key features include 64 KB Flash with ECC, 6 KB SRAM, a 10-bit SAR ADC with multiple channels, a 16-bit timer/capture unit (CCU6) for PWM generation, an integrated LIN 2.x transceiver conforming to SAE J2602, and on-chip NFET drivers capable of sourcing/sinking gate charge at the multi-milliampere level needed for automotive MOSFET switching. The IC supports multiple low-power modes (Sleep, Stop, Cyclic) for quiescent current budgets typical of always-on body-control networks. The architecture couples an Arm Cortex-M3 DSP-capable core with the application-specific peripheral set (CCU6, ADC, gate drivers, LIN). Hardware state machines and the CCU6 block offload PWM and commutation timing from the CPU, leaving headroom for closed-loop control algorithms, LIN stack processing, and safety diagnostics. ECC-protected Flash and brown-out / watchdog functions target ISO 26262 ASIL-B capable systems when used with an external safety companion or proper software partitioning. Typical applications include 12 V automotive BLDC water pumps, HVAC blower fans, fuel-pump modules, and auxiliary pumps where the LIN bus is the primary command interface and PCB area is at a premium. The integrated LIN transceiver also makes the part a natural fit for LIN-actuated seat fans and small radiator cooling modules. When designing with the TLE9877QXA40, mind thermal dissipation in the VQFN-48 exposed pad; tie the EP to a sufficiently large copper pour (≥1 cm²) and respect the 0.5 mm pitch during PCB layout. Always validate NFET selection against the driver's gate-drive capability and confirm LIN bus dominant timeouts against your network schedule table. This page synthesizes distributor pricing, drop-in MOTIX family alternatives, and practical design notes that go beyond the manufacturer datasheet summary to help engineers compare the TLE9877QXA40 against competing solutions in real BOM contexts.

The 8-pin SOIC and 3 mm × 3 mm SON options give designers a layout choice for both through-hole-style reflow and space-constrained modules. Architecturally the device combines a high-side driver with active current limiting, a recessive-side pull-up, a comparator-based receiver, and a state machine for wake-up pulse recognition; this integration removes the need for an external LIN pull-up resistor and a TVS diode in moderate-environment designs. Typical applications include body control modules, HVAC control panels, steering-wheel switch interfaces, door/window lift switches, seat-position memory modules, and LED lighting controllers. The wide VSUP range and integrated fault protection suit 12-V automotive battery systems including cold-crank and load-dump conditions.

It supports data rates up to 20 kbps on the transmitter path and up to 100 kbps on the receiver for faster in-line programming. The part targets 12-V automotive networks with a wide 4.5 V to 36 V supply range and extended bus-fault protection rated at ±45 V, alongside greater than ±8 kV HBM and IEC ESD protection levels on the LIN bus pin. A LIN transceiver is the physical-layer interface for the LIN (Local Interconnect Network) bus, a single-wire, low-speed serial protocol widely used for in-vehicle body and comfort networks such as door modules, seat controllers, mirror switches, and HVAC actuators. The TLIN1039-Q1 belongs to the family of automotive LIN transceivers within the broader category of interface ICs / physical-layer transceivers, sitting beneath the CAN/LIN/FlexRay hierarchy of in-vehicle networking standards. Its role is to translate CMOS-level TXD/RXD logic into the dominant/recessive current-driven LIN bus waveform that meets the LIN 2.0/2.1/2.2/2.2A, ISO/DIS 17987-4 and SAE J2602-1 physical-layer specifications. Key features of the TLIN1039-Q1 include integrated local and remote wake-up support, a current-limited wave-shaping driver that reduces electromagnetic emissions (EME), an open-drain RXD output for flexible logic interfacing, internal pull-down on TXD for fail-safe behavior, dominant-state time-out protection, and ±45 V bus-fault tolerance with thermal shutdown. The combination of wide operating voltage, bus-fault ruggedness and AEC-Q100 Grade 1 qualification makes the part well suited to harsh automotive electrical environments including jump-start, load-dump and reverse-battery transients. Architecturally, the device combines a bandgap-referenced voltage regulator, a current-limited open-drain LIN driver with slew-rate control, a window comparator receiver, and a state-machine that handles dominant time-out, thermal shutdown, under-voltage lockout and wake-up detection. The integrated ESD cell on the LIN pin exceeds ±8 kV HBM, eliminating the need for an external TVS in most 12-V automotive LIN node designs. Typical applications include body control modules, door/window/seat/mirror modules, HVAC control nodes, steering column switches, lighting ECUs, and sensor/actuator nodes that must interface with a LIN master in an in-vehicle network. The receiver's higher 100 kbps capability also enables faster in-line programming of slave ECUs over the LIN bus. When designing with this device, ensure that VSUP is decoupled with a 100 nF ceramic capacitor close to the pin, and that the LIN bus pin is protected by the bus-pin ESD structure rather than an external TVS, since adding a TVS can load the bus and disturb the LIN waveshaping. The TXD pin must not be pulled high to VSUP, as TLIN1039-Q1 only provides an internal pull-down.

TLIN829-Q1

TLIN829-Q1 - Fault-Protected LIN Transceiver, 20kbps | TI

The Texas Instruments TLIN829-Q1 is an automotive fault-protected Local Interconnect Network (LIN) physical-layer transceiver with integrated dominant-state timeout, supporting data rates up to 20kbps and operating from a wide 5.5V to 28V supply (with extended fault tolerance above 28V). Housed in an 8-pin SOIC or 8-pin SON (DRB 3x3) package, it converts a TXD logic-level data stream into a single-wire LIN bus waveform via a current-limited wave-shaping driver, and converts the bus signal back to logic levels through an open-drain RXD pin. The transceiver complies with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, SAE J2602, and ISO/DIS 17987-4 standards. According to TI product page data, the LIN receiver additionally supports fast in-line programming at rates up to 100kbps. The TLIN829-Q1 is a 12V-system optimized, cost-effective derivative of the TLIN1029A-Q1 and TLIN1029-Q1 family, sharing the same family footprint and adding wider operating voltage, bus-fault protection, and a dominant-state watchdog that prevents the bus from being stuck in the dominant state due to software or hardware faults. What is a LIN transceiver? A LIN (Local Interconnect Network) transceiver is a physical-layer (PHY) device that connects a microcontroller's UART-style logic domain to a single-wire, low-cost automotive communication bus. It typically integrates a wave-shaping transmitter, a comparator-based receiver, bus fault protection (against shorts to battery, ground, and adjacent LIN nodes), ESD protection, and a low-power wake-up mechanism. LIN sits hierarchically under in-vehicle networking alongside CAN (Controller Area Network), FlexRay, and Automotive Ethernet - LIN targets low-speed, low-cost nodes like door modules, mirror adjusters, and seat controllers, while CAN/Ethernet handle higher-bandwidth powertrain and ADAS domains. Key features include: integrated dominant-state timeout for fail-safe bus recovery, ±45V LIN bus fault tolerance (load-dump tolerant), ±15kV HBM ESD on the LIN pin per IEC 61000-4-2, ultra-low quiescent current in sleep mode, thermal shutdown, and an active-high WAKE input that wakes the device from sleep without MCU intervention. The part supports both 3.3V and 5V MCU logic via a separate VCC/VSUP rail scheme. The 8-pin SOIC (D) and 8-pin SON (DRB 3x3) packages provide small footprint for space-constrained body-electronics modules. Typical applications include automotive body control modules (BCM), HVAC control, door/window/seat modules, steering column controls, rain/light sensors, mirror adjusters, headlamp leveling, and interior lighting nodes. The part's AEC-Q100 Grade 1 qualification (-40C to +125C) makes it suited for underhood and cabin applications alike. Designers should ensure proper LIN bus termination (typically a master pull-up of 1kΩ plus a diode to VSUP, and a slave pull-up of 30kΩ in the device), use a 100nF X7R decoupling capacitor close to VSUP, and route the LIN trace as a short, stub-free single-ended line, twisted if possible, to minimize radiated emissions. The dominant-state timeout is configurable; refer to the datasheet's register or strap-setting description for the chosen mode.

TLP7820(A-LF4

TLP7820(A-LF4 - 5 kVrms Isolated Amplifier | Toshiba

The Toshiba TLP7820(A-LF4 is a one-channel optically isolated amplifier with analog output, 5000 Vrms isolation, and a SO8L (LF4) package. It operates from 3 V to 5.5 V, supports differential input sensing, and is designed for high-precision current sensing in electronic motor drives. The isolation barrier transfers a measured voltage signal optically while electrically separating the sensed power circuit from downstream control electronics. An isolation amplifier is an analog signal-conditioning IC that combines input amplification, modulation across a galvanic isolation barrier, and signal reconstruction at the output. Unlike a conventional voltage amplifier, its primary purpose is to measure a differential signal while maintaining high-voltage isolation. This places it in the isolated-sensing branch of the industrial, power-conversion, and motor-control semiconductor hierarchy. Key verified characteristics include a 3 V to 5.5 V supply range, differential sensing, 5000 Vrms isolation, and analog output. Toshiba identifies motor phase current sensing and inverter current or voltage sensing as primary use cases. In a typical motor-drive circuit, motor current flows through an external shunt resistor and the resulting differential voltage is measured by the amplifier. The device architecture provides an analog output while preserving a reinforced-style isolation barrier up to the verified 5000 Vrms rating. Its single-channel SO8L package supports compact isolated signal-conditioning layouts, but the exact pin assignments, input range, bandwidth value, propagation behavior, accuracy limits, and temperature limits must be taken from the manufacturer datasheet. Typical applications include three-phase inverter phase-current measurement, DC motor control, industrial inverter monitoring, power-supply current feedback, and isolated analog voltage sensing. The differential architecture suits shunt-based measurements where common-mode voltage is elevated or varies with the switching environment. PCB design should preserve creepage and clearance around the isolation barrier, keep input and output grounds separate, and place the shunt path and amplifier inputs according to the manufacturer layout guidance. Filtering near the sensor input may be needed if switch-node transients exceed the device limits; component values should not be inferred without the complete datasheet specifications. This page consolidates the verified manufacturer and distributor information, separates confirmed TLP7820 characteristics from unavailable parameters, and provides engineering-oriented application and sourcing context rather than treating packaging-code variants as engineering alternatives.

TLP7820(A-TP4 - 5kVrms Isolated Amplifier | Toshiba

The Toshiba TLP7820(A-TP4 is a photocoupler-based isolation amplifier with analog output, 5000 Vrms reinforced isolation, and an 8-pin SO8L package. It is designed primarily for motor phase-current and inverter voltage sensing. The verified source data identifies one differential isolation-amplifier circuit and an 8-SO package, while detailed electrical characteristics are not provided in the supplied records. An isolation amplifier is an analog signal-conditioning IC that transfers voltage information across a galvanically isolated barrier while electrically separating high-voltage circuitry from the low-voltage control domain. In the application hierarchy, the TLP7820 belongs to isolation amplifiers, optically isolated amplifiers, signal-conditioning ICs, analog ICs, and semiconductor devices. Its isolation barrier helps prevent ground faults and high common-mode potentials from reaching measurement, protection, or control electronics. Toshiba identifies the TLP7820 as an analog-output isolation amplifier rated to 5000 Vrms. The official product description specifically targets current sensing in electronic motor drives, where an external resistor produces a voltage proportional to motor current. The TLP7820 senses that voltage across its isolated input side and presents the result on the non-isolated output side. The provided records also associate the device with power-inverter current sensing. The isolation mechanism is optical within a photocoupler-type package. Optical isolation breaks the direct conductive path between input and output while preserving the intended analog signal relationship. In practical systems, the amplifier is paired with a precision shunt resistor, power-supply bypassing, an analog acquisition stage, and a controller such as a motor-drive MCU. Exact gain, bandwidth, input range, common-mode limits, supply requirements, and accuracy must be confirmed in the manufacturer datasheet before release to production. Typical uses include three-phase motor-drive shunt sensing, inverter leg-current measurement, power-converter feedback, and isolated analog-voltage sensing across a high-voltage barrier. Unlike ordinary operational amplifiers placed directly beside a shunt, the TLP7820 provides a defined isolation function suited to systems where the sensed node can sit at a hazardous or elevated potential. PCB design should preserve the isolation barrier by maintaining the package creepage and clearance required by the working voltage and applicable safety requirements. Place input-side and output-side ground returns independently, route copper so isolation barriers cannot be bridged by solder, test pads, or silkscreen-dependent features, and use stable references and supply decoupling appropriate for the measurement accuracy required. This page consolidates the verified Toshiba product-page data, distributor identification, sourcing links, and engineering cautions that are not presented together in the manufacturer overview. Because the supplied web records do not expose a complete parametric datasheet, unsupported values are intentionally marked for verification rather than inferred from generic isolation-amplifier specifications.

In a typical implementation, motor current flows through an external resistor and the resulting analog voltage drop is sensed by the isolation amplifier. Its differential input arrangement helps reject common-mode voltage at the shunt, while the 5000 Vrms isolation rating supports high-side sensing in inverter and motor-control systems. The analog output can be connected to a controller or monitoring ADC after the system designer confirms the required transfer gain, bandwidth, accuracy, and supply conditions. The verified Toshiba material also references EN IEC 60747-5-5 option (D4) documentation, which is relevant when evaluating isolation-related product qualification requirements. The part is associated with motor phase-current sensing, inverter current sensing, and inverter voltage sensing. The available LCSC listing reports a 5-piece stock example and a starting price of $11.3258, but pricing and inventory are market-dependent and were not provided as a structured XAIPART price schedule. A practical design must preserve the isolation barrier rather than treating SO8L as an ordinary op-amp package. Keep high-voltage and low-voltage copper regions separated, route the shunt signal as a short differential pair, provide local supply bypassing where the datasheet specifies it, and verify creepage, clearance, capacitor insulation, and system-level withstand requirements. The TLP7820(B-LF4 is best considered for isolated measurement in power-conversion equipment after checking the exact option suffix and datasheet revision. This page consolidates manufacturer product information, distributor findings, and cross-reference evidence into an engineering-oriented overview. It distinguishes verified information from fields that still require the latest Toshiba datasheet or authorized distributor quote, helping designers evaluate the TLP7820 without substituting unverified ratings or assuming that a similar package implies drop-in compatibility.

The available evidence supports the device category, isolation rating, analog-output architecture, package family, and target sensing applications. Typical implementation places the TLP7820 across a current-sense shunt or inverter phase-current sensing path. Its isolation barrier allows measurement information to cross from the power stage toward a controller while maintaining galvanic separation. Designers should verify the complete recommended shunt, input filter, supply, output, and grounding configuration in the Toshiba datasheet and evaluate the external resistor network for the intended current range. Design emphasis belongs on barrier isolation, common-mode voltage limits, input-referenced filtering, output scaling, and PCB creepage. The SO8L package should be placed with adequate isolation clearance and a defined high-voltage barrier; copper, slots, and grounded structures must not unintentionally reduce the rated isolation distance.

The TLP7820 belongs to the optically isolated amplifier category, which is part of the broader interface IC and industrial signal-conditioning hierarchy. Its optical isolation barrier helps protect low-voltage measurement circuitry from high-side motor-drive voltages while preserving accurate current information. Key device attributes include a one-channel isolation amplifier configuration, analog differential output, 5 V operation, 5000 Vrms isolation rating, and an 8-pin SO8L package. The precision-amplifier-based signal path is intended for DC current measurement rather than general-purpose AC isolation. Differential output helps reject common-mode voltage and noise present across the external shunt, improving measurement fidelity in electrically noisy power-electronic systems. Toshiba positions the TLP7820 for electronic motor drives where current flows through an external resistor and the resulting analog voltage drop is sensed by the isolation amplifier. The isolation barrier allows the sensor interface to remain electrically separate from the inverter or motor supply. Compared with a discrete shunt amplifier and optocoupler combination, the integrated device can reduce board area and simplify signal-chain assembly, although system-level creepage, capacitance, and layout requirements still require careful review. Typical applications include motor phase-current monitoring, inverter current sensing, power-converter feedback, industrial motor controls, and isolated DC measurement systems. These systems benefit from the 5000 Vrms isolation capability and analog output while requiring suitable input filtering, supply decoupling, and a low-impedance measurement network. Designers should follow the manufacturer datasheet for the exact pin assignment, recommended shunt value, input range, output configuration, permissible isolation, and application circuit. PCB creepage and clearance must be maintained across the isolation barrier, and the analog input and output paths should be kept compact and away from high-voltage switching nodes.

TLP7820(D4BTP4

TLP7820(D4BTP4 - 5000 Vrms Isolation Amplifier | Toshiba

Toshiba Semiconductor and Storage TLP7820(D4BTP4 is an optically isolated, precision current-sensing amplification IC with an analog output and 5000 Vrms isolation rating, supplied in an 8-pin SO8L (LF4) package. The device supports isolated measurement of DC motor phase current and inverter voltage, combining an internal precision amplifier, isolation barrier, and analog output stage in one compact component. Its key differentiating attributes are the 5000 Vrms reinforced insulation capability, isolation-amplifier topology, differential input arrangement, and gain-rank-B configuration. The D4 designation identifies a variant qualified according to option D4 of EN IEC 60747-5-5. An isolation amplifier is a type of analog signal-conditioning IC used to transfer a measurement across a high-voltage barrier while maintaining galvanic isolation between the sensed circuit and the host electronics. The broader hierarchy is isolation amplifier to signal-conditioning IC to interface IC to semiconductor. Unlike an ordinary shunt amplifier, an optically isolated current-sense amplifier combines measurement and isolation in one package. This allows a controller, inverter, or monitoring system to process a high-current power rail without sharing its ground or exposing its low-voltage electronics to the hazardous domain. The TLP7820 family is specifically associated with accurate DC current measurement and motor phase-current sensing. Its differential input accepts current information from an external shunt, while the internal amplifier provides a scaled analog output suitable for an analog-to-digital converter. The analog output architecture gives designers a continuous voltage representation of measured current and permits system-specific scaling through external components. The product page identifies current sensing, power management, motor phase current sensing, and inverter current and voltage sensing as principal uses. From a practical perspective, the 5000 Vrms isolation rating is the device’s most prominent headline specification. Reinforced isolation separates the measured high-side or low-side power domain from the control side and is useful in industrial drives, traction equipment, renewable-energy inverters, and other systems where a shunt may be positioned at a substantial potential above system ground. Optical isolation also prevents ground currents from contaminating the measurement path, provided the complete channel satisfies applicable creepage, clearance, and installation requirements. The B suffix denotes gain rank B, as confirmed by the Mouser product listing. This rank supports accurate DC current measurement with a built-in precision amplifier, making the part appropriate for motor control feedback where offset, scaling, and channel behavior must remain predictable. Exact input range, gain tolerance, bandwidth, supply requirements, output swing, and temperature limits must be confirmed in the manufacturer datasheet before final design release. A key implementation consideration is that isolation performance depends on the entire board, not only the IC. The input-side and output-side ground domains must remain separated, the device must be placed to satisfy required creepage and clearance distances, and the analog output must be routed away from high-dv/dt switching nodes. The analog trace should be short, referenced to the output-side ground, and protected from capacitive coupling through careful placement of shunt, amplifier, and protection components. This page combines verified manufacturer and distributor information, explicit qualification details, source-backed product options, and application-focused engineering guidance. It distinguishes verified facts from specifications that still require confirmation from the current Toshiba datasheet, helping engineers evaluate the TLP7820(D4BTP4 without relying on incomplete distributor summaries.

Toshiba TLP7820(LF4 is a one-channel optically isolated amplifier with analog output, rated for 5000 Vrms isolation and supplied in an 8-pin SO8L (LF4) package. The verified product data identifies differential sensing and a supply range of 3 V to 5.5 V, while the related distributor listings identify the device for motor phase-current and voltage sensing. Its isolated measurement architecture transfers a differential analog signal across a high-voltage barrier, supporting current feedback and protection functions in inverter and motor-drive systems. The SO8L package and 8-SO outline make it suitable for compact isolated-control boards. An isolation amplifier is a signal-conditioning IC that combines an input stage, an isolation barrier, and an output stage. The input stage measures a differential voltage, the barrier transfers that information while maintaining galvanic separation, and the output stage produces an analog voltage for an analog-to-digital converter or controller. In a motor-drive circuit, this arrangement measures voltage across a shunt resistor without connecting the high-voltage power stage directly to the controller ground. The verified data highlights analog output, differential operation, 5000 Vrms isolation, one circuit, and a 3 V to 5.5 V supply range. These features are directly relevant to current sensing in power converters and inverters. The isolation barrier allows sensing information to cross from a noisy power environment to a control domain while maintaining the required separation between those domains. Toshiba’s product page identifies the TLP7820 as an isolation amplifier and isolated delta-sigma modulator product. The manufacturer data retrieved for the device describes current sensing in electronic motor drives, where motor current flows through an external resistor and the resulting voltage drop is sensed. The D4 qualification information references EN IEC 60747-5-5 option D4 for designated part-number conventions, while the standard LF4 designation is used for the package and ordering variant shown here. Typical applications include three-phase inverter current sensing, motor phase-current measurement, DC-link voltage sensing in inverter systems, power-factor correction current feedback, and isolated gate-driver monitoring. The component is most appropriate when the analog sensor signal must remain galvanically isolated from a controller or ADC input. The primary design consideration is maintaining the manufacturer-specified layout and isolation-clearance requirements. The input network, shunt connection, output filtering, supply decoupling, and isolation barrier must be laid out according to the Toshiba datasheet. The verified data does not provide every pin name, electrical limit, thermal value, or timing parameter, so those details remain marked for data-needed rather than estimated.
