Infineon Technologies TLE82092EXUMA2

Overview

TLE82092EXUMA2 from Infineon Technologies is an AEC-Q100 qualified SPI-programmable dual half-bridge H-bridge IC for automotive DC motor control, featuring 240 mΩ typical full-path R_DS(on), 1.5–8.6 A programmable current limit, 4.5–28 V battery supply range, and integrated open-load/short-circuit/overtemperature diagnostics. It operates in safety-critical body electronics such as power window actuators and seat adjusters.

For engineers reviewing the TLE82092EXUMA2 datasheet, TLE82092EXUMA2 pinout, TLE82092EXUMA2 application, or TLE82092EXUMA2 equivalent, key selection criteria include SPI-configurable slew rate, dual-mode operation (H-bridge or independent half-bridges), VDD/VDDIO monitoring, thermal warning flag, and status flag fallback mode without SPI bus dependency.

Technical Context

The device integrates two N-channel high-side and two N-channel low-side power stages with gate drivers, charge pump, and digital logic core. Its dual control interface supports parallel TTL/CMOS inputs or 4-wire SPI (SCK, SI, SO, SS/SF) with configurable register mapping for current limit, slew rate, and fault masking.

Protection architecture includes VS undervoltage shutdown, VDD over/undervoltage monitoring, temperature-dependent current reduction above 165°C, and real-time diagnosis via SPI status registers or single-pin status flag output. All I/O pins are overvoltage tolerant to 18 V.

FAQ

What is the function of the VDDIO pin on TLE82092EXUMA2?

VDDIO supplies voltage to the logic output buffers and determines the high-level voltage of the SO, SS/SF, and ABE pins. It accepts 0–5.5 V, allowing direct interface with 3.3 V or 5 V MCUs without level shifters. When grounded, it forces Status Flag mode, disabling SPI functionality and activating the SS/SF pin as an open-drain fault indicator.

Does TLE82092EXUMA2 support bidirectional motor control without external components?

Yes - the integrated dual half-bridge topology enables full H-bridge operation with only external flyback diodes (recommended) and the CP capacitor. No external MOSFETs, gate drivers, or current-sense resistors are required to implement reversible DC motor control with programmable current limiting and slew rate.

How does open-load diagnosis work in off-state on TLE82092EXUMA2?

During disable state (DIS = high), the device applies a small test current through the output stage and measures resulting voltage to detect open circuits. This occurs automatically without SPI command and reports result via SPI status register or status flag pin, verifying load connectivity before enabling drive - critical for fail-safe actuator initialization.

Can TLE82092EXUMA2 operate with a 3.3 V microcontroller SPI interface?

Yes - the SI, SCK, and SS/SF pins accept 3.3 V logic levels (TTL/CMOS compatible), and VDDIO can be set to 3.3 V to match. SO output is level-shifted to VDDIO, ensuring clean 3.3 V SPI communication. VDD must remain at 4.4–5.25 V to power internal logic, requiring separate 5 V supply or LDO.
