A high-temperature H-bridge motor driver designed for DC motor control applications in automotive high temperature environments. With a maximum junction temperature of 200ºC, this driver is suitable for applications with an ambient temperature up to 150ºC. The IC includes four driver stages to control four external power MOSFETs. An external microcontroller provides the direction signal and the PWM frequency.
Additional Features
PWM and direction-controlled driving of four externally-powered NMOS transistors
High temperature capability up to 200°C junction
A programmable dead time is included to avoid peak currents within the H-bridge
Integrated charge pump to provide gate voltages for high-side drivers and to supply the gate of the external battery reverse protection NMOS
5V/3.3V regulator and current limitation function
Reset derived from 5V/3.3V regulator output voltage
A programmable window watchdog
Battery overvoltage protection and battery undervoltage management
Overtemperature warning and protection (Shutdown)
High voltage serial interface for communication
