TLE9883-2QTW62S - Infineon Technologies

概要

The MOTIX™ TLE9883-2QTW62S is designed to drive up to four external power NFETs

The MOTIX™ TLE9883-2QTW62S is part of the MOTIX™ TLE988x product family. It is a fully integrated 2-Phase motor driver with the industry standard Arm® Cortex®-M3 core, enabling the implementation of advanced motor control algorithms. It includes a bridge-driver to drive up to four external power NFETs for 2-Phase motor control. A dual stage charge pump enables low voltage operation and programmable charge current profile along with adaptive MOSFET control for optimized EMC. Its peripheral set includes a current sense amplifier, two successive approximation ADCs that can be synchronized with the capture and compare unit 7 for PWM generation and several 16-bit timers. A CAN-FD transceiver and MULTICAN+ controller are integrated as well to enable CAN-FD communication along with a number of general purpose I/Os. It includes an on-chip linear voltage regulator to supply external loads.

The safe switch of path developed according to ASIL-B enables to safely turn off the motor.

It is a highly integrated AEC-Q100 Grade 0 automotive qualified device enabling cost and space efficient solutions for mechatronic BDC motor drive applications such as pumps or HVAC blower.
