Product details

Overview

TLE92108231QXXUMA1 from Infineon is an automotive-grade 8-channel half-bridge MOSFET driver IC for DC motor control, supporting up to 16 external N-channel MOSFETs with adaptive gate control, dual current sense amplifiers (configurable gain), and drain-source short-circuit detection. It operates with 24-bit SPI configuration, delivers up to 25 kHz PWM frequency, and features AEC-Q100 qualification for seat control and body electronics.

For engineers reviewing the TLE92108231QXXUMA1 datasheet, TLE92108231QXXUMA1 pinout, TLE92108231QXXUMA1 application, or TLE92108231QXXUMA1 equivalent, key selection criteria include diagnostic depth (open-load, short-to-battery/GND), reverse battery protection capability, thermal shutdown behavior, and SPI-based off-state fault reporting.

Technical Context

The device integrates eight independent floating gate drivers with programmable adaptive turn-on/turn-off timing to reduce EMI and switching losses in PWM mode. Each channel supports high-side and low-side MOSFET activation, active freewheeling, and independent drain-source voltage monitoring for real-time short-circuit detection.

It implements a 24-bit SPI interface with daisy-chain capability, global error flag (GEF), and status register readback for diagnostics. The internal charge pump enables high-side drive without external bootstrap components, while two configurable current sense amplifiers support bidirectional sensing on either side of the load.

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 Amplifiers	Two channels, configurable gain - Supports high-side or low-side placement for overcurrent protection and bidirectional motor current measurement.
Diagnostic Coverage	Off-state open-load, short-to-battery, short-to-GND - Reported via SPI status registers for system-level fault handling.
Thermal Protection	Overtemperature warning + shutdown - Prevents latch-up during sustained overload or ambient temperature rise.
Sleep Mode Current	< 100 µA - Minimizes battery drain in vehicle standby states such as door lock or window lift idle.
Reverse Battery Protection	Controlled via dedicated MOSFET driver - Enables safe operation in 12 V automotive systems with polarity reversal risk.
Package Thermal Resistance	R_thJA = 32 K/W - Ensures reliable power dissipation in compact body control module PCB layouts.

Pinout & Package

Housed in PG-VQFN-48 (VQFN-48 with exposed thermal pad), the package supports optical lead tip inspection and provides low thermal resistance for high-current automotive motor drive applications.

Pin/Terminal	Circuit Role	Design Meaning
V_S	Main supply input	Connects to 12 V battery rail; monitored for undervoltage/overvoltage shutdown.
V_DD	Logic supply	Internal LDO output (5 V) powers digital core; monitored for brown-out protection.
CSO1 / CSO2	Current sense amplifier outputs	Analog outputs scaled per configured gain; used for closed-loop current limiting and direction detection.
INx / ENx (x=1–8)	SPI-controlled gate enable inputs	Per-channel activation signals derived from SPI register writes; support static or PWM mode.
OUTxH / OUTxL (x=1–8)	Half-bridge high-side / low-side outputs	Drive external N-MOSFET gates; each pair forms one half-bridge with cross-conduction protection.
SDSx (x=1–8)	Drain-source voltage monitor inputs	Direct connection to MOSFET drain terminals for short-circuit detection during off-state.
CSN / SCLK / MOSI / MISO	SPI interface signals	24-bit serial interface with daisy-chain support; MISO includes global error flag (GEF) bit.
WDI	Watchdog input	Requires periodic SPI command or external pulse to prevent timeout-induced fail-safe shutdown.

Key Features

Feature	Design Value
Adaptive gate control	Reduces EMI by modulating slew rate and minimizes switching losses across PWM duty cycles.
Dual configurable current sense amplifiers	Supports ±10 mV to ±100 mV input range with selectable gain; enables high-accuracy motor stall detection.
Drain-source short-circuit detection	Monitors each MOSFET independently during off-state to distinguish open-load from short-to-rail faults.
Reverse battery protection control	Dedicated driver channel manages external MOSFET to block reverse current flow without diode loss.
SPI daisy-chain capability	Enables multi-device control with single MCU interface, reducing wiring and pin count in BCU modules.

Applications

Use Value: Enables precise, quiet, and fault-resilient motion control with real-time short-circuit and open-load diagnostics reported over SPI.

Use Scenario: Actuation of solenoid locks and feedback-driven latch mechanisms across all four doors and trunk.

IC Role / Device Role / Timing Role: Drives high-side/low-side MOSFETs for bidirectional solenoid control and monitors current to detect jammed or failed actuators.

Use Value: Provides fail-safe lock/unlock sequencing with off-state diagnostics that distinguish mechanical binding from electrical open circuits.

Body Control Module (BCM)

Rear Wiper & Washer System

Use Scenario: Integrated control of window lift, cargo cover, mirror folding, and washer pump within a single BCM PCB.

IC Role / Device Role / Timing Role: Consolidates eight independent motor/solenoid loads using shared SPI bus and centralized diagnostics.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS724G	Single high-side switch (1 channel), no SPI interface, no current sense amplifiers	Limited to simple on/off loads; lacks diagnostic depth and multi-channel coordination	Use only for non-critical, single-load applications where cost and simplicity outweigh diagnostic needs.
TLE9104	4-channel high-side driver with SPI, but no low-side or half-bridge capability, no drain-source monitoring	Cannot drive bidirectional motors or implement reverse battery protection	Select when only unidirectional high-side control is required and diagnostic scope is limited to overcurrent/thermal events.

Compared with BTS724G and TLE9104, the TLE92108231QXXUMA1 uniquely combines eight half-bridge channels, adaptive gate control, dual current sensing, and comprehensive off-state diagnostics-making it the only option qualified for coordinated multi-motor automotive body functions requiring functional safety awareness.

FAQ

What is the maximum PWM frequency supported by the TLE92108231QXXUMA1?

The device supports PWM frequencies up to 25 kHz, which is optimized to avoid audible noise in DC motor applications while maintaining sufficient resolution for torque and speed control. This frequency is achievable across all eight channels simultaneously and remains stable under full thermal load with proper PCB thermal design.

Does the TLE92108231QXXUMA1 support both high-side and low-side current sensing?

Yes-it integrates two fully configurable current sense amplifiers that can be routed to either high-side or low-side shunt placements via SPI register settings. Each amplifier offers selectable gain (10×, 20×, 50×, 100×) and supports bidirectional current measurement for motor direction detection and stall identification.

How does the device handle short-circuit detection during motor off-state?

Each SDSx pin continuously monitors the drain-source voltage of its associated external MOSFET while the device is in off-state. If V_DS exceeds threshold during this period, the device flags a short-to-battery or short-to-GND condition in the corresponding SPI status register-enabling precise fault localization without motor activation.

Is the TLE92108231QXXUMA1 pin-compatible with earlier TLE9210x variants?

No-TLE92108231QXXUMA1 uses the PG-VQFN-48 package with specific pin assignments defined in Infineon's Rev. 2.0 datasheet. While functionally aligned with the TLE92108 family, pin mapping differs from legacy versions like TLE92104, and direct replacement requires PCB layout revision and firmware validation.
