Product details

Overview

TLE92108232QXXUMA1 from Infineon is an AEC-Q100 qualified automotive 8-channel half-bridge gate driver IC for controlling external N-channel MOSFETs in DC motor applications. It integrates two configurable current sense amplifiers, drain-source short-circuit detection per channel, overtemperature warning/shutdown, and a 24-bit SPI interface for configuration and diagnostics. Used in seat control, power lift gates, and body control modules.

For engineers reviewing the TLE92108232QXXUMA1 datasheet, TLE92108232QXXUMA1 pinout, TLE92108232QXXUMA1 application, or TLE92108232QXXUMA1 equivalent, key selection considerations include adaptive gate control for EMI reduction, high-side/low-side PWM capability up to 25 kHz, off-state diagnostics (open load, short-to-battery, short-to-GND), and VS overvoltage detection in sleep mode.

Technical Context

The device implements eight independent floating gate drivers with adaptive MOSFET gate control logic that dynamically adjusts turn-on/turn-off delays based on real-time drain-source voltage feedback-reducing electromagnetic emissions and switching losses in PWM operation. Each channel supports static activation, active freewheeling, and bidirectional current sensing via dedicated CSO outputs.

Its SPI interface enables full register-based configuration of protection thresholds (e.g., temperature warning level, VS overvoltage trip), diagnostic reporting (global error flag, per-channel fault status), and operational modes (normal, sleep, fail-safe). The charge pump supplies gate drive voltage for high-side MOSFETs, with undervoltage monitoring and blanking during cross-current events.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	8 independent half-bridge gate drivers for external N-channel MOSFETs
PWM Frequency	Up to 25 kHz - supports precise speed/torque control in automotive actuators
Current Sense	Two amplifiers with programmable gain (10×/20×/40×/80×) - enables high-side or low-side placement for overcurrent and motor direction detection
Diagnostic Coverage	Per-channel drain-source monitoring + off-state open-load/short-circuit detection - reported via SPI status registers
Thermal Protection	Overtemperature warning at 150 °C and shutdown at 175 °C - prevents thermal runaway in enclosed modules

Pinout & Package

Housed in a PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad, this leadless power package supports optical lead tip inspection and delivers low thermal resistance (R_thJA = 35 K/W).

Pin/Terminal	Circuit Role	Design Meaning
VDD	Logic supply input	3.3 V ±5 % digital core supply; decoupling required near pin
VS	Main power supply input	5.5–28 V battery rail; powers gate drivers and charge pump
GND	Power and logic ground	Common reference for all analog/digital circuits; separate GND planes recommended
CSO1, CSO2	Current sense amplifier outputs	Analog voltage outputs proportional to sensed current; configurable for high-side or low-side sensing
IN0–IN7	Logic-level PWM inputs	Accept 3.3 V CMOS signals; support high-side and low-side PWM modes independently
EN	Enable input	Active-high global enable; forces all outputs to high-impedance when low
MISO/MOSI/SCLK/CSN	SPI interface signals	24-bit SPI with daisy-chain capability; CSN active-low chip select
ERR	Global error flag output	Open-drain signal asserted low on any fault condition (thermal, overvoltage, watchdog timeout)

Key Features

Feature	Design Value
Adaptive gate control	Dynamically adjusts turn-on/turn-off timing per MOSFET using real-time V_DS feedback - reduces EMI and conduction losses without external tuning
Configurable low-side brake	1–4 channels可 configured as active low-side brake with short-circuit detection in both normal and sleep modes - enables fail-safe motor hold
SPI-based diagnostics	24-bit interface reads per-channel fault flags (open load, short-to-battery, short-to-GND) and global status (temperature, VS, charge pump) - eliminates need for external ADC or monitoring circuitry
Reverse battery protection control	Dedicated gate driver output for external reverse-polarity MOSFET - allows system-level protection without additional controller
VS overvoltage detection in sleep mode	Monitors battery rail during low-power state and triggers wake-up or shutdown - prevents damage during jump-start or alternator surge

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS7200-2EPA	Single 2-channel high-side driver; no half-bridge topology, no current sense amplifiers, no SPI diagnostics	Limited to simple on/off loads (e.g., lamps, fans); unsuitable for bidirectional motor control or closed-loop current monitoring	Select when only basic high-side switching is needed and diagnostic depth is not required
TLE9183QX	3-channel half-bridge with integrated current sense and SPI; lower channel count, no adaptive gate control, different package (VQFN-32)	Targeted at smaller actuators (e.g., mirror adjust, HVAC flaps); lacks low-side brake configuration and VS overvoltage detection in sleep mode	Select for space-constrained designs where 3 channels suffice and advanced EMI mitigation is not critical

Compared with BTS7200-2EPA and TLE9183QX, the TLE92108232QXXUMA1 uniquely combines eight half-bridges, adaptive gate control, dual current sense amplifiers, and comprehensive off-state diagnostics - making it optimal for complex, safety-aware automotive body electronics requiring high integration and minimal external components.

FAQ

What is the maximum PWM frequency supported by the TLE92108232QXXUMA1?

The device supports PWM frequencies up to 25 kHz, enabling precise motor speed and torque regulation in automotive actuators. This limit ensures reliable switching performance while maintaining adequate dead-time control and minimizing gate driver power dissipation. Operation above 25 kHz may compromise fault response time and thermal stability under continuous load.

Does the TLE92108232QXXUMA1 support high-side and low-side current sensing simultaneously?

Yes - its two current sense amplifiers can be independently configured for high-side or low-side placement via SPI register settings. Each amplifier offers four selectable gains (10×, 20×, 40×, 80×) and outputs an analog voltage (CSO1/CSO2) proportional to sensed current, supporting bidirectional motor control and overcurrent protection in both directions.

How does the adaptive gate control reduce electromagnetic emissions?

Adaptive gate control monitors each MOSFET's drain-source voltage in real time and dynamically adjusts turn-on and turn-off delay times to avoid hard switching during voltage transitions. This soft-switching behavior suppresses high-frequency ringing and dv/dt spikes - directly lowering conducted and radiated EMI without requiring external snubbers or ferrite beads.

Can the TLE92108232QXXUMA1 operate in vehicle battery undervoltage conditions?

Yes - it operates across VS = 5.5 V to 28 V, covering cold-crank scenarios down to ~6 V. Internal undervoltage lockout (UVLO) disables outputs below 5.5 V to prevent erratic behavior, and the device resumes normal operation once VS rises above the hysteresis threshold (~5.8 V), ensuring robust startup in low-battery conditions.
