BLDC-Motor Driver with Cold-Crank Capability | E523.10 (*SoC)
The IC is a system base chip for driving BLDC and DC motors in B6, full bridge or half bridge applications.
The IC ensures a safe, autonomous start-up and wake-up. It is suitable for high temperature applications. An integrated linear regulator supplies an external microcontroller. The supply output current can be "boosted" with an external transistor.
For controlling the motor, six power FET gate drivers with automated dead time generation are implemented.
Measurement functions for motor current, battery voltage and temperature are implemented.
The IC has integrated programmable safety functions on motor over current, battery over and under voltage, over temperature and short circuits at all six power FETs.
