Product details

Overview

TLE92104232QXXUMA1 from Infineon Technologies is a quad half-bridge MOSFET driver IC for automotive DC motor control, supporting up to eight external N-channel MOSFETs, featuring 24-bit SPI configuration, dual current sense amplifiers (configurable gain), and drain-source short-circuit detection per channel. It operates in normal/sleep/fail-safe modes with adaptive gate control for EMI reduction and PWM switching up to 25 kHz - deployed in power seat and lift gate actuation systems.

For engineers reviewing the TLE92104232QXXUMA1 datasheet, TLE92104232QXXUMA1 pinout, TLE92104232QXXUMA1 application, or TLE92104232QXXUMA1 equivalent, key selection criteria include diagnostic depth (open-load, VS overvoltage, thermal warning), low-side brake configurability in sleep mode, and AEC-Q100 qualification for body electronics.

Technical Context

The device integrates four independent half-bridge drivers with adaptive gate control logic that dynamically adjusts turn-on/turn-off delays based on MOSFET V_DS feedback, reducing electromagnetic emissions and conduction losses during PWM operation. Each bridge supports high-side and low-side PWM inputs with active freewheeling capability.

Diagnostic architecture includes two current sense amplifiers (high-side/low-side configurable), real-time drain-source monitoring per MOSFET, timeout watchdog, and comprehensive off-state diagnostics (open load, short-to-battery, short-to-GND) reported via SPI status registers.

Key Specifications

Parameter	Value and Actual Design Meaning
PWM frequency	Up to 25 kHz - enables precise speed control of automotive DC motors without audible noise.
SPI interface	24-bit serial peripheral interface - provides full register access for configuration and diagnostic readback.
Current sense	Two amplifiers with selectable gain - supports bidirectional motor current measurement for torque and stall detection.
Protection features	Drain-source short detection, VS overvoltage/undervoltage, overtemperature warning & shutdown - ensures fail-safe operation in harsh environments.
Operating modes	Normal, Sleep, Fail-Safe - sleep mode enables <100 µA quiescent current with configurable low-side brake and VS OV detection.
Package thermal resistance	R_thJA = 35 K/W (typ.) - VQFN-48 exposed pad enables efficient heat dissipation in compact PCB layouts.
AEC qualification	AEC-Q100 Grade 1 (−40 °C to +125 °C ambient) - validated for under-hood and cabin body control applications.

Pinout & Package

Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad - optimized for optical lead tip inspection and high-power density mounting.

Pin/Terminal	Circuit Role	Design Meaning
V_S	Main supply input	Connects to battery rail (5.5–28 V); monitored for over/undervoltage shutdown.
V_DD	Logic supply	Internal LDO output (5 V) powers digital core; undervoltage detection triggers reset.
CSO1 / CSO2	Current sense outputs	Analog outputs of configurable-gain amplifiers; used for real-time motor current feedback.
PWM1–PWM3	PWM control inputs	Three dedicated inputs support high-side/low-side PWM; enable active freewheeling and 25 kHz operation.
EN	Enable input	Hardware enable signal; deassertion forces all bridges into safe state and enters sleep mode.
MISO/MOSI/SCLK/CSN	SPI interface	24-bit SPI bus for configuration, status readback, and diagnostic reporting.
OUT1H–OUT4L	Bridge outputs	Eight terminals (four high-side, four low-side) drive external N-MOSFET gates in half-bridge topology.

Key Features

Feature	Design Value
Adaptive gate control	Dynamically adjusts MOSFET turn-on/off timing using V_DS feedback to reduce EMI and switching losses in PWM mode.
Configurable low-side brake	Brake function (1–4 channels) active in both normal and sleep modes with integrated short-circuit detection.
Dual current sense amplifiers	Independent high-side/low-side configuration allows flexible placement for motor current sensing in H-bridge or 3-phase topologies.
Comprehensive off-state diagnosis	Detects open load, short-to-battery, and short-to-GND on each output - reported via SPI status register without MCU intervention.
VS overvoltage detection in sleep mode	Monitors battery rail during low-power state to prevent damage from load dump transients while minimizing current draw.

Applications

Power Seat Control

Power Lift Gate

Use Scenario: Bidirectional actuation of multi-axis seat mechanisms (fore/aft, recline, lumbar) requiring precise torque and position control.

IC Role / Device Role / Timing Role: Quad half-bridge driver controlling eight external N-MOSFETs; manages PWM timing, current feedback, and fault response per axis.

Use Value: Adaptive gate control reduces EMI in cabin environment; off-state diagnostics prevent false triggers from harness disconnection.

Use Scenario: Controlled lifting/lowering of vehicle rear hatch with soft-stop, obstacle detection, and anti-pinch behavior.

IC Role / Device Role / Timing Role: Motor driver with integrated current sensing and short-circuit protection - enables real-time torque estimation and emergency stop.

Use Value: Dual CSA inputs allow simultaneous high-side and low-side current sampling for accurate stall detection and smooth deceleration.

Central Door Lock

Body Control Module (BCM)

Use Scenario: High-reliability locking/unlocking of all doors using solenoid or small DC motor actuators.

IC Role / Device Role / Timing Role: Half-bridge driver enabling bidirectional solenoid control or motor reversal; supports low-duty-cycle pulse operation.

Use Value: Sleep-mode low-side brake maintains mechanical lock state with sub-100 µA current; VS OV detection prevents latch failure during jump-start.

Use Scenario: Integrated control of washer pump, rear wiper, cargo cover, and window lift functions within single BCM ECU.

IC Role / Device Role / Timing Role: Multi-channel driver consolidating discrete FET drivers; SPI interface enables centralized diagnostics and firmware updates.

Use Value: Daisy-chain SPI capability allows multiple TLE92104-232 devices on one bus - simplifying wiring and reducing MCU GPIO count.

Equivalent & Alternatives

The following parts are listed as comparable options for similar multi-MOSFET driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BD37102FV	Triple half-bridge (6-channel), no adaptive gate control, lower max PWM frequency (10 kHz), no sleep-mode VS OV detection.	Limited to simpler actuators (e.g., mirror fold) without torque-sensitive or low-power requirements.	Choose when cost sensitivity outweighs diagnostic depth and EMI performance.
TPIC2603D	Quad high-side switch (not half-bridge), no current sensing, no SPI diagnostics, fixed 12 V operation only.	Suitable only for unidirectional loads (e.g., lamps, fans) without motor control or safety-critical feedback.	Select only for non-motor, non-diagnostic, high-side-only applications with minimal feature set.

Compared with BD37102FV and TPIC2603D, the TLE92104232QXXUMA1 uniquely combines quad half-bridge topology, adaptive gate control, dual CSA, and AEC-Q100 sleep-mode diagnostics - making it the only option qualified for torque-controlled, fail-safe automotive motor actuation.

FAQ

Is TLE92104232QXXUMA1 pin-compatible with earlier TLE92104 variants?

No - the TLE92104232QXXUMA1 uses the PG-VQFN-48 package with specific pin assignments defined in Infineon's Rev. 1.0 datasheet (2020-09-21). Pin compatibility is not guaranteed across suffix variants (e.g., -231 or -233), as internal register mapping and protection thresholds differ. Always verify against the exact part number's pinout diagram before PCB layout.

Does this IC integrate charge pump circuitry for high-side gate driving?

Yes - the TLE92104232QXXUMA1 includes an internal charge pump generating ~10 V for high-side N-MOSFET gate drive. The charge pump voltage is monitored for undervoltage faults, and its operation is automatically managed during PWM and static activation modes per half-bridge configuration.

Can the current sense amplifiers be used simultaneously for high-side and low-side sensing?

Yes - both CSO1 and CSO2 are independently configurable for high-side or low-side current sensing via SPI register settings. This allows concurrent measurement of motor phase current and recirculation current, supporting advanced control algorithms like field-oriented control in adapted implementations.

What is the maximum junction temperature and thermal derating behavior?

The device is rated for junction temperatures up to +150 °C (absolute maximum), with thermal shutdown triggered at +175 °C. Derating begins at +125 °C ambient (Grade 1), where output current capability decreases linearly to 50% at +150 °C ambient - specified in Section 4.3 (Thermal Resistance) and Section 7.7 (Temperature Monitoring) of the datasheet.
