TLE9185QXXUMA1

Overview

The Infineon TLE9185QXXUMA1 is an automotive-grade three-phase gate driver IC designed for Brushless DC (BLDC) motor applications. It integrates power supply circuitry and diagnostic features within a PG-VQFN-48 package. The device supports PWM and SPI interfaces, operates on a 3V to 28V supply voltage, and withstands load voltages from 6V to 28V. It functions reliably across a junction temperature range of -40°C to 175°C and holds AEC-Q100 Grade 0 qualification.

Feature Summary

Integrates three half-bridge outputs with NMOS technology for direct BLDC motor control
Includes internal power supply management and dedicated current sense amplifier support
Features comprehensive diagnostic capabilities including overcurrent protection and thermal monitoring

Applications

Automotive cooling fan motors
Electric power steering systems
Water pump drives in vehicle thermal management

Procurement Notes

Verify the specific suffix 'X' against official documentation to confirm pinout and feature set variations. Confirm AEC-Q100 Grade 0 compliance requirements match the target application. Check for end-of-life notifications as discontinuation status may affect long-term availability. Ensure PCB layout accommodates the exposed pad thermal requirements of the PG-VQFN-48 package.

Selection Notes

Select this component when a single-chip solution for three-phase BLDC control is required with integrated diagnostics. Compare against the TLE9186 series if different packaging or updated feature sets are preferred. Ensure the system design supports the 3V to 28V operating voltage range. Verify that the SPI interface speed and PWM input requirements align with the chosen microcontroller.

Part Context

This part belongs to the MOTIX family of gate driver ICs from Infineon Technologies. It is specifically engineered for robust automotive environments requiring high reliability and functional safety readiness. The device simplifies motor drive designs by combining power stages with control logic and protection mechanisms in a compact form factor.
