E52301C78B

LIN2.x or PWM interface. 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 wakeup. 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 dynamically programmable, very precise dead time generation are implemented. Versions driving two half bridges only are available.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.Two product versions with a “state of the art” LIN2.2A or bidirectional PWM interface are available. The LIN interface supports flash mode to upload a new firmware to the microcontroller."
