TLE4476DATMA1 - Dual 3.3V/5V 350/430mA LDO Regulator | Infineon
The Infineon TLE4476DATMA1 is a monolithic dual low-dropout (LDO) linear voltage regulator that delivers a fixed 3.3 V output at up to 350 mA (Q1) and a fixed 5.0 V output at up to 430 mA (Q2) from a single PG-TO252-5-11 (TO-252 / DPAK 4+Tab) surface-mount package. Both rails are derived from the same unregulated input supply, allowing a system designer to power a microcontroller and its peripheral or interface circuitry from one IC. The device belongs to Infineon's OPTIREG LINEAR family and is qualified for harsh automotive and industrial environments. A Low-Dropout (LDO) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage approaches the output voltage within a few hundred millivolts. In the broader power-management taxonomy, an LDO is a sub-class of linear regulators, which sit alongside voltage regulators and DC-DC converters as members of the power management integrated circuit (PMIC) family used in virtually every electronic system. The Q1 3.3 V rail is sized for microcontroller core and memory supplies, while the Q2 5.0 V rail is sized for CAN transceivers, sensors, and 5 V logic. The 5 V output can also be used to feed a second-stage LDO for sub-rails requiring tighter noise or accuracy. The device is designed to operate from a wide input range suitable for 12 V automotive battery systems and includes integrated protection features such as over-temperature shutdown and short-circuit current limiting on both outputs. From an architecture standpoint, the regulator combines a bandgap reference, two independent error amplifiers with pass transistors, and protective circuitry on a single die. The fixed output voltages eliminate external feedback resistor dividers, reducing component count and PCB area. The 5-pin PG-TO252-5-11 package provides a low thermal resistance path via the exposed tab, supporting sustained high-current operation on both rails simultaneously. Typical applications include automotive body and chassis ECUs, infotainment controllers, industrial PLCs, sensor interfaces, and any system that needs to derive both 3.3 V and 5 V from a single 12 V battery rail. The TLE4476DATMA1 is often paired with Infineon TLE42744 or TLE42764 LDOs for post-regulation. When designing in this part, ensure both rails' worst-case load currents are summed when sizing the PCB copper pour on the tab. Maintain a solid ground return and place input/output capacitors close to the package to keep dropout and ripple within spec.

TLE4678ELXUMA2 - 5V 200mA LDO w/ Reset | Infineon OPTIREG
The Infineon TLE4678ELXUMA2 is a monolithic integrated low-dropout fixed-output voltage regulator delivering up to 200 mA continuous load current at a fixed 5 V output, housed in a thermally enhanced PG-SSOP-14-EP exposed-pad package. Input voltage range extends up to 45 V, output noise is optimized for automotive sensor and MCU rails, and the device integrates a reset/watchdog circuit for microcontroller supervision, along with current limiting and overtemperature protection. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is only marginally above the output. LDO regulators sit in the broader hierarchy of voltage regulators under DC-DC and linear regulators, themselves a sub-class of power management ICs. They are valued for their low noise, simplicity, and absence of switching EMI, making them the preferred post-regulator for noise-sensitive analog, sensor, and microcontroller supply rails. Key specifications include the 5 V fixed output, 200 mA continuous load, 45 V maximum input, low quiescent current consumption in normal operation, and an integrated reset generator with adjustable threshold. The exposed-pad PG-SSOP-14-EP package keeps thermal resistance low so the regulator can sustain 200 mA at high VIN without entering thermal shutdown, while the SSOP body footprint remains compatible with hand and reflow soldering. The TLE4678ELXUMA2 uses a monolithic bipolar process integrating pass element, reference, reset comparator, and protection logic. The reset output asserts low when VOUT falls below the programmed threshold, providing a clean MCU brown-out signal. The watchdog can be serviced by the host controller to verify firmware health, an important safety feature for automotive ECUs. Typical applications include automotive body and chassis ECUs, sensor supplies, dashboard controllers, and industrial microcontroller rails requiring 5 V regulation from 12 V or 24 V bus. The reset/watchdog integration reduces BOM count versus a separate LDO plus supervisor. When designing with this part, place input and output ceramic capacitors close to the IC pins, observe the minimum output capacitance requirement specified by Infineon, and tie the exposed pad to a copper pour for heat extraction. The reset delay capacitor value sets the assertion pulse width and must be chosen per application timing. This page synthesizes distributor pricing, drop-in alternatives, and design notes specific to the TLE4678ELXUMA2 footprint, providing practical information not consolidated on the manufacturer datasheet.
TLE4678GMXUMA2 - 5V 200mA LDO w/ Reset | Infineon OPTIREG
The Infineon TLE4678GMXUMA2 is a monolithic integrated low-dropout fixed-voltage regulator that delivers up to 200 mA at a factory-set 5 V output from a 45 V-rated input rail, housed in a 14-pin PG-DSO-14 surface-mount package (also available as PG-SSOP-14 exposed-pad). The TLE4678GM variant combines a precision 5 V LDO with an integrated microprocessor reset generator and watchdog, plus comprehensive protection circuits such as current limit, overtemperature shutdown, and reverse-polarity robustness. Its 350 mV typical dropout at full load lets it ride through automotive cold-crank and load-dump events while still maintaining a regulated MCU rail. The IC belongs to Infineon's OPTIREG Linear family, designed for harsh 12 V/24 V automotive and industrial environments with operating temperatures up to 150 °C junction. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable, low-ripple output voltage even when the input voltage approaches the output voltage, by using a pass element (typically a PNP bipolar or PMOS transistor) operating in the linear region. Within the broader power-management hierarchy, LDOs sit beneath switching converters as a final-stage clean-up regulator — supplying noise-sensitive analog, microcontroller, and sensor loads directly from a higher, often noisy, intermediate bus. The TLE4678GM specifically targets automotive body, chassis, and powertrain ECUs where a single-chip 5 V rail plus supervisory functions reduces board area and BOM cost compared with a discrete LDO plus reset/watchdog IC. Key features include ±2 % output voltage accuracy, integrated power-on reset with adjustable delay, window watchdog, current-limit foldback, thermal shutdown, and an enable input. The reset and watchdog thresholds are factory-trimmed for 5 V systems, simplifying firmware bring-up. The wide input range up to 45 V also tolerates 24 V industrial transients and clamped load-dump pulses typical of automotive electrical systems. Technically, the TLE4678GM uses a vertical PNP pass transistor architecture with a bandgap reference, achieving low quiescent current (typically under 5 mA at light load) and excellent line/load transient response. The exposed-pad (PG-SSOP-14) version lowers thermal resistance for continuous high-current operation; the PG-DSO-14 GM version is pin-compatible with the older TLE4278 for easy migration. Typical applications include automotive body control modules, instrument clusters, HVAC controllers, and industrial PLCs requiring a regulated 5 V rail with microprocessor supervision. The reset and watchdog outputs free designers from adding an external supervisor IC. When designing with this device, place the input bulk capacitor close to VIN, use a low-ESR 1 µF minimum on VOUT, and ensure PCB copper area under the exposed pad is sufficient to keep junction temperature below 150 °C at maximum dissipation. Watchdog timing capacitor selection must follow the datasheet's RC table to avoid spurious resets.

TLE6289GP - 6-Channel Peak-and-Hold Switch | Infineon
The Infineon Technologies TLE6289GP is a smart 6-channel peak-and-hold switch integrated circuit for automotive power-management and load-driving systems. The verified distributor listings identify the device as a gate-driver IC and a 6-channel peak-and-hold switch, while the available search data does not expose a complete manufacturer datasheet. Exact electrical ratings, channel logic, timing, and automotive qualification therefore require confirmation in the manufacturer datasheet before a new design is released. The GP order code denotes Infineon's automotive-oriented package family, but its exact package dimensions, pin count, and terminal assignments must also be verified against the official document. A TLE6289GP is useful where several controlled outputs must share common protection, diagnosis, or peak-and-hold behavior. Six integrated channels can reduce discrete component count and board area compared with separate switched loads, although the common-device architecture also concentrates failure and thermal-management considerations. Engineers should compare the TLE6289GP with the specific load, short-circuit, surge, and diagnostic requirements of the target vehicle platform. The verified market listings support gate-driver and power-management categorization, but they do not establish whether every output has a dedicated diagnostic path, how the channels behave during overload, or whether the device supports cascading or individual shutdown. Those details directly affect suitability in pump, motor, solenoid, relay, and electronic-valve systems. The TLE6289GP is best treated as an automotive smart-switch candidate rather than a generic MOSFET driver. Its in-circuit value depends on matching the integrated protections to the load, validating the supply and pin definitions, and checking thermal performance at the maximum simultaneous switching duty cycle. This page distinguishes verified market facts from unverified technical assumptions and identifies the parameters that still require manufacturer-source confirmation.
TLE7181EMXUMA1 - 4-Ch Half-Bridge MOSFET Gate Driver | Infineon
The Infineon TLE7181EMXUMA1 is a 4-channel half-bridge gate driver IC dedicated to driving 4 N-channel power MOSFETs forming the converter stage of high-current DC motor drives in the automotive sector. Housed in a 24-pin PG-SSOP-24-4 (exposed-pad SSOP) package with non-inverting logic, it operates from a 5.5V to 28V supply range, supports up to 1.5A peak source/sink gate drive current, and provides an SPI/digital diagnostic interface with comprehensive fault feedback. The device is AEC-Q100 qualified, making it suitable for safety-relevant automotive applications such as electric power steering (EPS), electric water pumps, engine cooling fans, and brake-by-wire actuators. A gate driver IC is a power-management semiconductor that sits between a low-power microcontroller or logic controller and the high-current gate of a power MOSFET or IGBT. Its primary function is to level-shift logic-level PWM signals to the higher voltages required to fully enhance the power MOSFET, provide high peak current to rapidly charge and discharge the gate capacitance for fast switching, and protect the controller from the high-voltage switching transients present on the half-bridge. In the broader taxonomy, gate drivers belong to the power management family, sit alongside low-side drivers, high-side drivers, and isolated gate drivers, and serve as critical building blocks in motor-control, DC-DC, and inverter subsystems. Key features of the TLE7181EMXUMA1 include four independent half-bridge outputs capable of configuring as two full H-bridges, integrated charge pump for 100% duty-cycle high-side drive, programmable dead-time generation, short-circuit and over-current detection via dedicated current-sense comparator, under-voltage lockout (UVLO) on both VCC and VBS rails, overtemperature shutdown, and a serial peripheral interface (SPI) for fault read-back and configuration. The exposed thermal pad (PG-SSOP-24-4) provides a thermal resistance of approximately 31 C/W, allowing continuous operation at moderate switching frequencies in sealed automotive environments. Typical applications include brushed DC motor control in EPS systems, brushless DC (BLDC) motor pre-drivers, electric coolant and oil pumps, HVAC blower fans, transmission solenoids, and general-purpose automotive H-bridge inverters up to several hundred watts. A PWM/DIR interface allows direct connection to a microcontroller's timer peripherals for closed-loop current or speed control. The device's 12V support and integrated protection features reduce external component count, simplifying the design of ISO 26262-compliant motor drive subsystems. When designing with the TLE7181EMXUMA1, attention must be paid to PCB layout around the bootstrap capacitors, gate-drive loop minimization, and thermal management of the exposed pad. Designers should follow Infineon's reference design and application notes to achieve robust short-circuit detection and reliable operation across the automotive -40C to +150C temperature range.
TLE7189F - 3-Phase Bridge Driver IC | Infineon Technologies
The Infineon TLE7189F is a 3-phase motor driver IC that controls 6 to 12 external MOSFETs forming the converter for high-current 3-phase BLDC motor drives in the automotive sector. It supports up to 30 kHz PWM switching frequency, integrates short-circuit detection and diagnostic features, and is AEC-Q100 qualified. The device is housed in a 48-pin PG-VQFN (VQFN-48-4) power package with an exposed thermal pad for superior heat dissipation under high-side/low-side gate-drive switching losses. A 3-phase bridge driver IC belongs to the broader category of gate drivers (also called motor driver pre-drivers or half-bridge drivers) within the semiconductor power management hierarchy: gate driver -> motor driver IC -> power management IC -> semiconductor. It functions as the intelligent control interface between a low-power microcontroller PWM block and a high-current 3-phase MOSFET bridge, handling level shifting, dead-time insertion, charge-pump generation, and protection logic. Without such drivers, microcontrollers cannot directly switch the multi-ampere currents required by automotive 48V or 12V brushless DC motors used in pumps, fans, and eBikes. Key features of the TLE7189F include integrated over-voltage shutdown monitored at Vs and VDH pins, short-circuit protection per phase, programmable dead time to prevent shoot-through, a charge pump for 100% duty-cycle high-side drive, and an SPI/diagnostic interface for fault feedback. The IC accepts low-battery operation down to 6V (cranking survival) and operates across -40C to +150C junction temperature. The 30 kHz PWM capability supports both trapezoidal and field-oriented control (FOC) algorithms. Typical applications span automotive BLDC pumps (water/oil/fuel), electric power steering (EPS), HVAC blowers, eBike traction drives, and 12V/48V mild-hybrid cooling fans. In each scenario the TLE7189F replaces discrete bootstrap-driver designs, reducing BOM count and PCB area by ~40% while providing ASIL-friendly diagnostic outputs. Designers should place the bootstrap capacitors as close as possible to the BSTx pins, use a low-ESR 1uF to 4.7uF ceramic on VCC, and ensure the exposed pad is soldered to a copper area of at least 1 cm^2 to keep junction temperature within AEC-Q100 limits. The datasheet documents a 29-page revision 2.1 from May 2007; refer to the manufacturer datasheet for the full device specification set.

TLE7244SLXUMA2 - 8-Ch Low-Side SPI Relay Driver | Infineon
The Infineon TLE7244SLXUMA2 is an 8-channel low-side power switch in PG-SSOP-24-7 package, delivering 290 mA per channel and designed specifically as a relay driver in automotive body and chassis applications. It operates from a supply range of 5 V to 28 V (3 V to 5.5 V logic supply), provides an SPI control and diagnostic interface, and offers four direct input pins for parallel control and PWM operation. Each of the eight outputs is protected against over-current, over-temperature, and short-circuit to ground and to battery. What is a low-side SPI relay driver? A low-side power switch is a type of power distribution IC that sits between the load (typically a relay coil, solenoid, or lamp) and ground, sinking current to switch the load on or off. When controlled by an SPI (Serial Peripheral Interface) link, a single microcontroller can manage many outputs with latched commands, while the driver handles the heavy current and protective functions locally. Low-side drivers belong to the broader category of power management ICs and, more specifically, intelligent load drivers / smart power switches used in automotive electronic control units. Key features of the TLE7244SLXUMA2 include eight open-drain N-channel outputs rated at 290 mA continuous, integrated protection with current limiting and thermal shutdown per channel, an SPI interface for diagnostics and configuration, four dedicated input pins for direct control or PWM generation, a limp-home function to maintain operation under microcontroller fault, and very low quiescent current in standby. The PG-SSOP-24-7 exposed-pad package provides excellent thermal dissipation and is qualified to Infineon's automotive reliability standards. Architecturally, the device pairs eight N-channel DMOS output stages with a digital control core that decodes SPI frames, drives fault flags, and arbitrates between direct-input and SPI commands. The embedded protective functions - over-current, open-load, over-temperature, and reverse battery - are designed to satisfy OEM body-controller module requirements, while the diagnostic word returned over SPI supports ISO 26262 functional-safety development at the system level. Typical applications include automotive body control modules driving relays and solenoids, junction box power distribution, lighting drivers (especially where PWM dimming is required), HVAC flap motors, and other inductive loads where protective switching and diagnostics are essential. The four input pins make it equally suitable as a stand-alone relay driver without MCU intervention during limp-home. When designing with this part, keep output flyback diodes or use relays with built-in freewheeling diodes because the low-side switch cannot clamp inductive kickback on its own. The exposed thermal pad must be soldered to a sufficient copper area on the PCB to keep junction temperature within ratings when driving multiple inductive loads simultaneously.

TLE72732GV33XUMA1 - 3.3V 180mA LDO w/ Window Watchdog | Infineon
The Infineon TLE72732GV33XUMA1 is a monolithic low-dropout (LDO) linear voltage regulator with integrated window watchdog and reset, delivering a fixed 3.3V output at up to 180 mA load current from a 14-pin PG-DSO-14 (exposed pad) package. It is qualified to AEC-Q100 Grade 1 standards and operates over a wide 5.5V to 45V input voltage range, making it purpose-built for harsh automotive ECU environments. The integrated window watchdog supervises microcontroller activity and the reset output provides a defined power-on and undervoltage reset signal. An LDO (Low-Dropout) regulator is a type of linear voltage regulator that can maintain a stable output voltage even when the input voltage approaches the output voltage, with dropout typically under 500 mV. Within the broader power-management IC hierarchy, LDOs sit beneath switching regulators and are preferred for low-noise rails where efficiency is secondary to ripple rejection. The TLE7273-2G family occupies the automotive microcontroller-supply sub-segment, where integrated supervision (watchdog + reset) reduces external component count on the ECU PCB. Key features include ±2% output voltage accuracy, an integrated adjustable-window watchdog (via external resistor), a push-pull reset output with programmable reset delay, current limiting, thermal shutdown, and reverse-polarity protection on the input. The exposed pad on the PG-DSO-14 package provides low thermal resistance for sustained 180 mA loads at elevated ambient temperatures. The regulator uses a bipolar pass-element architecture combined with a bandgap reference, optimized for automotive transient robustness including jump-start and load-dump immunity per ISO 7637. The wide VIN window (up to 45 V transient) and AEC-Q100 Grade 1 qualification (-40 °C to +125 °C junction) make it well suited to under-hood and chassis ECUs. Typical applications include body control modules, gateway ECUs, sensor cluster power rails, HVAC controllers, and lighting ECUs. Any 12 V or 24 V automotive ECU requiring a regulated 3.3 V logic rail with built-in microcontroller supervision is a strong fit. When designing with this part, choose the external resistor at the WADJ pin carefully to set the watchdog window to match the microcontroller's service pulse timing - a misaligned window will trigger spurious resets. The exposed pad must be soldered to a sufficient copper pour to keep junction temperature within SOA at full 180 mA load.
TLE72742DATMA1 - 300mA 5V LDO Regulator, 42V Input | Infineon
The Infineon TLE72742DATMA1 is a monolithic integrated low-dropout (LDO) voltage regulator designed for automotive and industrial loads requiring up to 300 mA. Packaged in a PG-TO252-3 (DPAK) surface-mount outline with a thermally conductive tab, the device regulates a wide 5.5 V to 42 V input down to a fixed 5.0 V output with ±2 % accuracy. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input-to-output differential is small, making it ideal as a post-regulator following a pre-converter or for direct use on noisy automotive battery rails. Within the broader power management taxonomy, an LDO belongs to the linear regulator family, which is itself a sub-category of voltage regulators and ultimately part of the power management IC hierarchy used in every automotive ECU. Key features of the TLE72742DATMA1 include very low quiescent current in standby, integrated output current limiting, thermal shutdown, reverse-polarity protection, and stable operation with small ceramic output capacitors. The wide input voltage range tolerates load-dump transients up to 42 V typical in 12 V automotive systems, while the precision bandgap reference holds Vout within ±2 % across line, load, and temperature variation. The device is fabricated using Infineon's robust bipolar process technology optimized for automotive environments. The architecture combines a PNP pass element with comprehensive protection circuitry, enabling reliable operation at junction temperatures up to 150 °C while maintaining tight regulation. The PG-TO252-3 (DPAK) package features an exposed tab that serves as the heatsink, achieving a junction-to-ambient thermal resistance suitable for continuous 300 mA delivery. Typical applications include microcontroller power supplies in body control modules, sensor and actuator power rails, infotainment subsystems, and industrial 24 V bus regulation. Automotive grade qualification makes the part suited for under-hood and cabin-mounted ECUs requiring long-term reliability. Designers should provide adequate PCB copper area on the tab to keep junction temperature within limits, and place input/output ceramic capacitors close to the pins. The wide VIN range makes the device tolerant of cold-crank and load-dump conditions typical of automotive environments.

TLE75004EPDXUMA1 - 4-Ch Low-Side SPI Switch, 470mA | Infineon
The Infineon TLE75004EPDXUMA1 is a 4-channel low-side power switch with integrated N-channel MOSFETs, each capable of 470 mA continuous drain current, housed in a PG-TSDSO-14-41 exposed-pad package. The device integrates a 16-bit SPI interface for channel control and diagnostic readback, supports 3 V cranking capability for cold-start automotive conditions, and provides a fail-safe (Limp Home) mode that maintains critical outputs when the microcontroller or SPI link fails. A low-side switch is a power distribution topology in which the MOSFET is placed between the load and ground, allowing the load to be tied to a permanent supply rail (e.g., the vehicle battery). This architecture belongs to the broader category of smart power switches (SPS), which combine a power transistor, gate driver, protection circuitry, and a digital diagnostic interface in a single IC. Smart low-side switches have largely replaced discrete MOSFETs + fuses in body electronics because they provide per-channel current limiting, overload shutdown, open-load detection, and thermal protection without external sense resistors. Key features of the TLE75004EPDXUMA1 include per-channel current limiting, open-load detection in both on and off states, over-temperature shutdown with auto-restart, short-to-ground and short-to-battery protection, and reverse battery protection via an external resistor. The SPI interface operates at clock rates up to 5 MHz, allowing fast update of output states and rapid polling of fault registers. An IDLE pin enables the Limp Home mode where input pins directly drive the outputs without SPI intervention. Typical applications include automotive body control modules (BCMs), door modules, seat controllers, and LED lighting drivers where multiple low-current relays, solenoids, or LEDs must be switched under microcontroller supervision. The PG-TSDSO-14-41 package provides an exposed thermal pad that keeps junction temperature low even when all four channels are delivering full current simultaneously. When designing with this part, ensure the SPI lines are pulled up to VCC and the IDLE pin is tied high for normal SPI-controlled operation. The exposed pad must be soldered to a sufficiently large copper pour (at least 1 cm²) to achieve the datasheet thermal resistance. According to the manufacturer datasheet, the device is qualified to AEC-Q100 Grade 1, making it suitable for under-hood and other harsh automotive environments.
TLE75080ESDXUMA1 - 8-Ch SPI High-Side Switch, 330mA | Infineon
The Infineon TLE75080ESDXUMA1 is an 8-channel high-side power switch in a PG-TSDSO-24-21 (exposed pad) package, delivering 330 mA per channel for automotive and industrial relay and LED loads. Each channel integrates an N-channel MOSFET with active current limiting, and the device communicates over a 16-bit SPI interface for diagnostics and PWM control. A high-side switch (also called a smart power switch) is a semiconductor device that sits between a load and the positive supply rail. It replaces mechanical relays and discrete MOSFETs by combining a power transistor with protection, diagnostic, and communication circuitry. High-side switches sit in the family hierarchy: high-side switch -> power distribution switch -> power management IC -> semiconductor, and they enable centralized load control in body control modules, BCMs, and zonal architectures. Key features include 8 independently controlled channels, 16-bit SPI daisy-chain capability, integrated reverse-battery protection, open-load detection in on and off states, overtemperature shutdown with per-channel thermal sensors, and a Limp Home mode that allows safe operation at 3.0 V cranking transients. The device operates across a wide 4.5 V to 28 V supply range and withstands load-dump transients up to 40 V. The architecture uses N-channel MOSFETs with charge-pump-driven gates for true low-RDS(on) switching. Each channel includes current-limit set registers, individual fault flags, and PWM generation up to several hundred Hz. The exposed-pad package provides a thermal resistance below 30 C/W on standard 2 oz copper, supporting sustained 330 mA output per channel. Typical applications include automotive body electronics (lighting, HVAC blowers, seat control), industrial PLC relay drivers, and 24 V LED matrix modules. The combination of SPI diagnostics and cranking tolerance makes it well suited for 12 V automotive subsystems that must survive cold-crank events down to 3 V. When designing with this part, allocate PCB area for the exposed thermal pad and connect it to a solid copper pour. The Limp Home feature requires the SPI watchdog to be configured in the application firmware; an unconfigured watchdog defaults to fail-safe behavior. Per-channel current limit registers must be tuned to the load to avoid nuisance trips on inrush loads such as incandescent lamps or DC motors. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes that supplement the manufacturer datasheet and accelerate your evaluation.
TLE75080ESHXUMA1 - 8-Ch SPI High-Side Switch 330mA | Infineon
The Infineon TLE75080ESHXUMA1 is an eight-channel high-side power switch in the PG-TSDSO-24-21 (TSDSO-24) package with 16-bit SPI control, integrated PWM generators, and Limp Home mode, designed for 12 V automotive and industrial loads. Each of the eight channels is rated at 330 mA continuous current and is built on Infineon's Smart Power SPIDER technology, integrating a vertical N-channel power MOSFET with charge pump, gate driver, current sense, and protective circuitry on a single die. The device operates from a nominal 12 V supply (with load-dump and jump-start tolerance typical of the TLE75080 family) and is qualified to AEC-Q100 for automotive body and chassis applications. Key features of this multichannel high-side switch include per-channel diagnostics (open load, short to battery, short to ground, overtemperature), parallel-input capability for direct MCU PWM control, a 16-bit SPI interface for configuration and status readback, and selectable latching or auto-restart fault behavior. The integrated charge pump drives the N-channel MOSFETs fully on at low battery voltage, achieving low R_DS(on) per channel. The Limp Home function allows a predefined safe output pattern if SPI communication is lost, critical for fail-operational body modules. Technically, the TLE75080-ESH belongs to the high-side switch category within the broader power distribution IC hierarchy: high-side switch -> smart power switch -> power management IC -> semiconductor. It is designed as an alternative to discrete MOSFET + fuse combinations, replacing many components with one SPI-controlled block. Each channel's integrated protection eliminates the need for external sense resistors, TVS clamps, and PTCs in many 12 V load drive circuits. Typical applications include automotive body control modules (BCM) driving lamps, LEDs, relays, and small motors; heating systems such as seat heaters and mirror heaters; industrial 24 V (rescaled) load switching; and energy/power distribution nodes in zonal E/E architectures. The PG-TSDSO-24-21 exposed-pad package enables direct PCB thermal dissipation without a heatsink at typical 12 V loads. When designing with this device, follow Infineon's PCB layout guidance for the exposed thermal pad, keep the SPI bus length short, and add a reverse-polarity protection diode at VBAT. Decouple VBAT and VS pins with a 100 nF ceramic plus a low-ESR electrolytic capacitor as recommended in the TLE75080-ESH datasheet. This page synthesizes distributor pricing, drop-in alternatives from the Infineon SPIDER family, and practical design notes for 12 V body-control applications that are not consolidated in the manufacturer datasheet.
TLE75602ESHXUMA1 - 8-Ch SPI Power Switch 330mA | Infineon
The Infineon TLE75602ESHXUMA1 is an 8-channel low-side and high-side SPI-controlled power switch housed in a PG-TSDSO-24-21 package, delivering up to 330 mA per channel for 12 V automotive and industrial loads. Built on Infineon's SPIDER (Smart Power Integration Device with Embedded Regulation) technology, the device integrates eight MOSFET output stages, a 16-bit SPI interface, configurable PWM generators per channel, and comprehensive diagnostic features in a single exposed-pad thermally enhanced surface-mount package. An SPI-controlled power switch (sometimes called a multi-channel high-side switch, low-side switch, or smart solid-state relay) is a power-management IC that replaces discrete MOSFETs, fuses, and relay driver circuitry with an integrated, microcontroller-addressable load driver. It sits hierarchically as a child of power distribution switches, which themselves are a sub-family of power management ICs. By consolidating eight independently controllable outputs behind a serial-peripheral-interface (SPI) command set, the TLE75602-ESH eliminates dozens of discrete components while providing per-channel fault reporting, current monitoring, and PWM dimming that discrete implementations cannot match. Key features include an operating voltage range that supports 3.0 V cranking transients (typical 4.5 V to 28 V with load-dump survivability above this range), per-channel Rds(on) in the sub-200 mΩ class, integrated reverse-battery protection via an external resistor, programmable overcurrent shutdown, open-load detection in both on and off states, and overtemperature pre-warning and shutdown. The 16-bit SPI runs at clock rates up to 5 MHz and allows parallel operation of multiple TLE75602 devices for systems requiring more than eight channels. Architecturally, each of the eight channels combines an N-channel MOSFET output stage with charge pump, gate driver, current-sense amplifier, and fault logic. The on-chip diagnostic block can flag short-to-battery, short-to-ground, open load, and overtemperature events back to the host microcontroller through dedicated SPI status registers, enabling ASIL-aware functional-safety implementations under ISO 26262.

The Infineon TLE82422LXUMA2 (die name TLE8242-2L) is an eight-channel low-side constant-current control pre-driver IC housed in a 64-pin PG-LQFP-64-4 package, designed for solenoid, valve, and LED driver applications in automotive and industrial systems. Each of the eight channels is independently configurable through the SPI interface and can operate in either direct PWM mode or closed-loop constant current mode by setting the appropriate CM bit in SPI message #1. The device operates from a supply range of 5.5 V to 42 V and is rated for junction temperatures from -40 °C to +150 °C, enabling use in harsh automotive underhood environments. What is a low-side constant-current pre-driver? A low-side pre-driver sits between a microcontroller and external low-side N-channel MOSFET switches, controlling the gate of each MOSFET to regulate current through grounded loads such as solenoids, valves, relay coils, or LED strings. By sensing drain current through an external shunt and modulating the external MOSFET gate, the pre-driver achieves tightly regulated load current independent of supply voltage or temperature variations. The "pre-driver" classification means the IC does not contain the power MOSFETs themselves - this architecture lets designers select external MOSFETs sized for the application's load current and thermal budget. Key features of the TLE82422LXUMA2 include eight independently controlled channels, integrated SPI for diagnostics and configuration, fixed-frequency constant-current control, per-channel current setpoints, comprehensive fault diagnostics (open load, short circuit, overtemperature), and a wide 5.5 V to 42 V supply range. The PG-LQFP-64-4 package provides a low-thermal-resistance surface-mount footprint compatible with standard reflow assembly. Each channel supports a configurable PWM frequency and duty cycle, allowing the same IC to drive mixed load types (e.g., proportional valves and on-off solenoids) from a single device. Architecture-wise, the TLE82422-2L integrates a precision current-sense amplifier per channel, an SPI slave controller with global and per-channel status registers, an internal 5 V logic regulator for digital supply, and gate drivers capable of sourcing and sinking the gate charge of standard logic-level N-channel MOSFETs. The constant-current regulation loop operates at a fixed switching frequency to minimize EMI by placing harmonics at predictable frequencies, simplifying input-filter and EMC compliance design. Typical applications include automotive transmission solenoids, electronic throttle and EGR valves, diesel injection valves, LED driver modules, industrial process control valves, and printer/plotter stepper motor drivers. The eight-channel density is particularly suited to mechatronic modules that require multiple coordinated actuators. When designing with this device, follow Infineon's reference layout for the PG-LQFP-64-4 exposed pad: solder the e-pad to a continuous ground copper pour to achieve the rated thermal resistance and to provide the low-impedance return path required for accurate current sensing. Decouple VS and VCC with low-ESR ceramic capacitors placed within 5 mm of the supply pins. This page synthesizes distributor pricing, drop-in alternative analysis, and practical design notes - including a same-family Infineon alternative - that go beyond the manufacturer datasheet's specification tables to help engineers rapidly evaluate the TLE82422LXUMA2 for their multi-channel actuator and constant-current applications.

The TLE83862ELXUMA1 uses a peak-current-mode control architecture with a low-side shunt resistor for current sensing, enabling cycle-by-cycle overcurrent protection and good transient response. The switching frequency is set by a single resistor at the RT pin, providing flexibility to optimize efficiency versus component size. The device integrates a high-side gate driver capable of driving logic-level N-channel MOSFETs in boost configurations for input voltages up to 45 V. Typical applications include automotive LED headlight boost converters, pre-boost supplies for downstream buck regulators in 12 V / 24 V automotive systems, USB-PD / Type-C adapter power stages, industrial 24 V to higher voltage rails, and battery-backed boost converters. The AEC-Q100 qualification makes it especially suited for harsh automotive environments subject to load-dump and cold-crank transients. When designing with this part, ensure the input capacitor is sized to handle the pulsating current of the boost topology, and route the low-side current-sense traces as a Kelvin connection to the shunt resistor to preserve current-mode control accuracy. The exposed pad must be soldered to a sufficiently large copper pour to keep junction temperature within the -40 C to +125 C operating range during load-dump events.

Key headline parameters include a 24 V supply voltage rating, 0.9 A overcurrent shutdown threshold per channel, and 1.3 Ohm typical on-resistance (RDS(on)) per switch. What is a half-bridge motor driver? A half-bridge driver is a power semiconductor topology containing two switches (high-side and low-side) that together drive one terminal of a load. A quad half-bridge IC integrates four such bridges on a single die, enabling flexible load configurations: two DC motors, one stepper motor (as two full H-bridges), four solenoids, four LEDs, or any combination. These ICs belong to the broader motor driver family, which sits under power management ICs in the system hierarchy (motor driver -> power management IC -> semiconductor). The half-bridge topology is the foundational building block of all H-bridge and 3-phase motor drivers. Key differentiating features include an SPI/parallel control interface, integrated freewheeling diodes, overcurrent shutdown with diagnostics, overtemperature protection, undervoltage lockout, and open-load detection. The BiCDMOS architecture allows logic-level inputs (3.3 V/5 V CMOS compatible) to directly drive the high-current DMOS outputs, eliminating external gate drivers and level shifters. Each half-bridge can deliver continuous load current up to its rated RDS(on) limit, and parallel-mode operation enables higher per-channel current. The TLE8444SL is targeted primarily at automotive body electronics and industrial motion control, where it controls small DC motors, stepper motors, relays, and solenoids. Its AEC-Q100 qualification makes it suitable for under-hood and body modules, while the parallel interface simplifies integration with microcontrollers that lack SPI peripherals. The SSOP-24 package with exposed pad provides low thermal resistance for sustained high-current operation. Typical applications include throttle and flap actuators in HVAC systems, headlight beam-leveling motors, DC and stepper motor control in industrial automation, and solenoid/valve drivers. The integrated diagnostics (open load, short to ground/battery, overtemperature) significantly reduce external protection circuitry. When designing with this device, ensure the supply voltage stays within the rated range and place a 100 nF decoupling capacitor close to the VBB pin. The exposed thermal pad must be soldered to a sufficient copper pour to handle the worst-case dissipation across all four channels. This page consolidates distributor pricing, parametric drop-in alternatives, and practical PCB-level design guidance not found in the manufacturer datasheet, making it a complete sourcing and engineering reference for the TLE8444SLXUMA1.

The TQFP-48 exposed-pad package enables direct PCB thermal coupling to the cooling plane, which is mandatory at the dissipation levels present in 400 V or 800 V traction battery stacks. Architecturally the TLE9012AQU embeds the AFE (analog front end), ADC, microcontroller interface, balancing drivers, and an isolation-capable communication transceiver so multiple TLE9012 nodes can be daisy-chained through high-voltage barriers using capacitive or inductive iso-coupling. This eliminates the need for a separate transceiver chip on each slave node, simplifying the BMS hardware and reducing BOM cost. Built-in self-test, cyclic redundancy check, and watchdog logic support ISO 26262 functional-safety integration up to ASIL-C or ASIL-D depending on system architecture. Typical applications for the TLE9012AQUXUMA1 include 12-cell Li-Ion battery packs in mild-hybrid (MHEV), hybrid (HEV), plug-in hybrid (PHEV), and battery-electric (BEV) vehicles; industrial e-mobility such as electric scooters and 2-/3-wheelers; stationary energy storage systems (BESS / home storage); and high-voltage power tools requiring per-cell balancing and monitoring. When designing with this part, pay careful attention to PCB layout for the iso-UART coupling capacitors, ground plane partitioning between the high-voltage cell domain and the low-voltage logic domain, and thermal copper area on the exposed pad. Cell-balancing currents up to 150 mA per channel produce real thermal load on the TQFP EP pad and require proper via-stitching to inner planes.
