Product details

Overview

TLE92104131QXXUMA1 from Infineon is a quad half-bridge MOSFET driver IC for automotive DC motor control, supporting up to eight external N-channel MOSFETs. It features 24-bit SPI configuration, adaptive gate control for EMI reduction and PWM switching loss minimization, and integrated current sense amplifier with configurable gain (10×/20×/40×) for high-side/low-side sensing. Used in seat control modules for steering column and gas pedal adjustment.

For engineers reviewing the TLE92104131QXXUMA1 datasheet, TLE92104131QXXUMA1 pinout, TLE92104131QXXUMA1 application, or TLE92104131QXXUMA1 equivalent, key selection criteria include diagnostic coverage (open-load, short-to-battery/GND), 25 kHz PWM capability, reverse battery protection control, thermal shutdown behavior, and VQFN-48 package thermal performance.

Technical Context

The device implements four independent half-bridge drivers with programmable adaptive gate control logic that dynamically adjusts turn-on/turn-off delays based on drain-source voltage feedback to suppress cross-conduction and reduce electromagnetic emissions. Each bridge supports both high-side and low-side PWM operation with active freewheeling.

SPI communication uses independent slave select (CSN) with daisy-chain capability and global error flag (GEF) reporting. Diagnostics include per-MOSFET drain-source monitoring, temperature warning/shutdown, VS/VDD/charge pump UV/OV detection, and timeout watchdog - all reportable via status registers accessible over SPI.

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.
Current sense gain	Configurable 10×/20×/40× - supports accurate overcurrent detection across varied motor load ranges.
Supply voltage range	V_S: 5.5 V to 28 V - compatible with 12 V and 24 V automotive battery systems including cold-crank conditions.
Sleep mode current	< 100 µA - enables low-power standby in body control modules during vehicle sleep cycles.
Thermal shutdown threshold	175 °C - protects against sustained overload or cooling failure in enclosed modules.
Diagnostic resolution	Per-half-bridge open-load, short-to-battery, and short-to-GND detection - enables localized fault isolation in multi-motor systems.

CSIP1 / CSIN1	Current sense inputs	Differential inputs for bidirectional current measurement; configurable gain via SPI register.
CSO1	Current sense output	Analog output scaled by configured gain; used for external ADC sampling or comparator triggering.
EN	Enable input	Hardware enable/disable controlling device power state and gate driver activation.
GND	Power and signal ground	Common reference for analog/digital domains; must be connected to exposed thermal pad.

Key Features

Feature	Design Value
Adaptive gate control	Reduces dv/dt-induced EMI and switching losses by dynamically adjusting gate drive strength based on real-time V_DS feedback.
Per-bridge diagnostics	Independent open-load, short-to-battery, and short-to-GND detection per half-bridge enables granular fault localization in multi-motor systems.
Reverse battery protection control	Dedicated control path for external reverse-polarity MOSFET allows system-level protection without additional ICs.
24-bit SPI with GEF	Global Error Flag provides single-bit fault indication across all protection circuits, simplifying host controller interrupt handling.
Drain-source blank time	Programmable blanking window prevents false overvoltage trips during MOSFET switching transitions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad half-bridge MOSFET driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE92108131QXXUMA1	Eight half-bridges (vs. four), identical SPI interface and diagnostics, larger VQFN-64 package.	Supports up to 16 MOSFETs; suited for higher channel count BMS or HVAC blower modules.	Select when scaling beyond four motor channels without redesigning firmware or layout.
BD3539FV-E2 (ROHM)	Quad half-bridge with 16-bit SPI, no adaptive gate control, fixed 10× current sense gain, no reverse battery control output.	Limited diagnostic scope (no per-bridge short-to-battery detection); lower EMI mitigation capability.	Consider only for cost-sensitive non-safety-critical applications where Infineon's AEC-Q100 qualification is not required.

Compared with TLE92104131QXXUMA1, the TLE92108131QXXUMA1 offers double channel density but requires more PCB area and higher SPI traffic overhead, while the BD3539FV-E2 lacks adaptive gate control and comprehensive off-state diagnostics - limiting its suitability for ASIL-B–related seat or door functions.

FAQ

What is the maximum PWM frequency supported by the TLE92104131QXXUMA1?

The device supports PWM frequencies up to 25 kHz, verified in the datasheet's electrical characteristics section (Table 13, "Switching parameters of MOSFETs in PWM mode"). This enables silent motor operation above audible range while maintaining sufficient resolution for precise speed regulation in seat and wiper applications.

Does the TLE92104131QXXUMA1 support both high-side and low-side current sensing?

Yes - the integrated current sense amplifier accepts differential inputs (CSIP1/CSIN1) and is configurable via SPI for high-side or low-side placement. Gain settings of 10×, 20×, or 40× allow accurate current measurement across motor startup surges and steady-state loads.

How does the adaptive gate control reduce electromagnetic emissions?

Adaptive gate control monitors each MOSFET's drain-source voltage in real time and adjusts turn-on/turn-off slew rates to minimize dv/dt spikes. This directly reduces broadband radiated emissions measured per CISPR 25 Class 5, as confirmed in Infineon's application note AN478.

Is the TLE92104131QXXUMA1 qualified for automotive use?

Yes - it is fully qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient), with validation documentation including HTOL, TC, UHAST, and ESD testing. The "QXXUMA1" suffix denotes AEC-Q100-compliant packaging and wafer fabrication.
