Infineon Technologies TLE95623QXXUMA1

Overview

TLE95623QXXUMA1 from Infineon is an automotive-qualified DC motor system IC integrating a 5 V/250 mA LDO regulator, four half-bridge gate drivers for external N-channel MOSFETs, a high-speed CAN FD transceiver (up to 5 Mbit/s), dual LIN transceivers (LIN2.2/J2602), four 7 Ω high-side outputs, two PWM inputs (≤25 kHz), and a 32-bit SPI with CRC - deployed in power lift gate and seat control modules.

For engineers reviewing the TLE95623QXXUMA1 datasheet, TLE95623QXXUMA1 pinout, TLE95623QXXUMA1 application, or TLE95623QXXUMA1 equivalent, key selection considerations include CAN FD partial networking wake-up capability, adaptive gate drive timing control, drain-source monitoring for open-load detection, and AEC-Q100 qualification for under-hood motor control systems.

Technical Context

The device implements a hierarchical state machine with six operational modes (Init, Normal, Stop, Sleep, Restart, Fail-Safe), each supporting configurable cyclic sense/wake functions and selective wake-up via CAN partial networking. It uses internal timers and hardware watchdogs (configurable time-out and window types) to enforce safety-critical transitions.

Its communication stack integrates ISO 11898-2:2016-compliant CAN FD transceiver with FD-tolerant mode and selective wake (SWK), plus LIN2.2 transceivers with programmable TXD time-out and flash mode - all supervised by diagnostic flags including BUSERR, WUF, CANTO, and SYSERR.

FAQ

What is the maximum supported PWM frequency for motor control?

The TLE95623QXXUMA1 accepts PWM inputs up to 25 kHz on its two dedicated PWM pins. This frequency supports smooth, low-noise DC motor commutation while maintaining sufficient resolution for torque regulation. The device's adaptive gate drive adjusts switching timing automatically to minimize losses at varying duty cycles and load conditions.

Does this IC include an integrated CAN FD transceiver or require external components?

Yes, the TLE95623QXXUMA1 integrates a fully compliant ISO 11898-2:2016 CAN FD transceiver supporting speeds up to 5 Mbit/s, partial networking selective wake-up, and FD-tolerant mode. No external CAN bus components are required beyond standard common-mode chokes and termination resistors on the physical layer.

How does the device handle reverse battery connection?

The IC does not integrate a reverse-battery protection MOSFET but provides dedicated control logic (RBP_CTRL pin) to drive an external N-channel MOSFET in the high-side path. This allows designers to select MOSFETs optimized for R_DS(on), thermal performance, and voltage rating - unlike fixed-integration alternatives.

Is the 5 V LDO output capable of powering an external microcontroller?

Yes, the integrated LDO delivers 5 V ±2% at up to 250 mA with dropout voltage below 300 mV at full load. It is designed to power automotive-grade MCUs, sensors, and communication peripherals - and remains active in Stop and Sleep modes to support wake-up readiness and low-power monitoring functions.
