Infineon Technologies TLE95603QXXUMA1

Overview

TLE95603QXXUMA1 from Infineon Technologies is an automotive-qualified DC motor system IC integrating a 5 V/250 mA low-dropout regulator, dual half-bridge gate drivers for external N-channel MOSFETs, high-speed CAN FD transceiver (up to 5 Mbit/s), LIN 2.2 transceiver, four 7 Ω high-side outputs, and SPI interface with CRC - deployed in power lift gate and seat control modules.

For engineers reviewing the TLE95603QXXUMA1 datasheet, TLE95603QXXUMA1 pinout, TLE95603QXXUMA1 application, or TLE95603QXXUMA1 equivalent, key selection criteria include CAN FD partial networking wake-up capability, adaptive gate control for PWM efficiency, drain-source monitoring with open-load detection, and AEC-Q100 qualification for body electronics systems.

Technical Context

The device implements a multi-state safety architecture with Init, Normal, Stop, Sleep, Restart, and Fail-Safe modes, each governed by configurable watchdogs (time-out and window), cyclic sense/wake timers, and fault-triggered transitions. It supports selective wake via CAN partial networking with WUP/WUF detection and SWK_SET flag management.

Its communication stack includes ISO 11898-2:2016-compliant CAN FD transceiver with FD-tolerant mode and LIN 2.2/SAE J2602 transceiver featuring programmable TXD time-out and flash mode - both enabling coordinated network entry/exit without host MCU intervention.

FAQ

What is the maximum supported PWM frequency for motor control?

The TLE95603QXXUMA1 accepts PWM inputs up to 25 kHz on its high-side and low-side inputs, enabling precise speed regulation and torque control for brushed DC motors. This frequency supports active freewheeling and minimizes audible noise in cabin applications such as seat and sunroof modules.

Does the device support CAN FD partial networking wake-up?

Yes - the integrated CAN FD transceiver complies with ISO 11898-2:2016 and supports selective wake-up via partial networking, including wake-up pattern (WUP) and wake-up frame (WUF) detection, SWK_SET flag assertion, and CAN bus silence monitoring - all configurable via SPI registers.

How does the adaptive gate control reduce switching losses?

Adaptive gate control dynamically adjusts gate drive strength to regulate MOSFET switching time, minimizing overlap between voltage and current during turn-on/turn-off. This reduces conduction and switching losses in PWM mode, especially critical in thermally constrained modules like door latches and lift gates.

Is optical lead tip inspection supported in the package?

Yes - the PG-VQFN-48-31 package features exposed copper leads compatible with automated optical inspection (AOI) systems, enabling reliable solder joint verification during SMT assembly. This supports zero-defect manufacturing goals for automotive Tier-1 suppliers.
