MOTIX™ TLE9877QXA40 is the perfect fit for auxiliary water pumps and support sensorless FOC
The MOTIX™ TLE9877QXA40 is part of the TLE987x product family. The MOTIX™ TLE9877QXA40 is a single chip 3-Phase motor driver that integrates the industry standard Arm® Cortex®-M3 core, enabling the implementation of advanced motor control algorithms such as field-oriented control. It includes six fully integrated NFET drivers optimized to drive a 3-Phase motor via six external power NFETs, a charge pump enabling low voltage operation and programmable current along with current slope control for optimized EMC behavior. Its peripheral set includes a current sensor, a successive approximation ADC synchronized with the capture and compare unit for PWM control and 16-bit timers. A LIN transceiver is also integrated to enable communication to the device along with a number of general purpose I/Os. It includes an on-chip linear voltage regulator to supply external loads.
It is a highly integrated automotive qualified device enabling cost and space efficient solutions for mechatronic BLDC motor drive applications such as water pumps.
