The bridge driver is dedicated to automotive 3 phase brushless DC motor control including safety relevant applications. It provides six dedicated drivers for normal level N-Channel MOSFET transistors. The driver capability is designed to handle gate charges of 250 nC, and the driver source/sink currents are programmable for easy output slope adjustment. The device also incorporates sophisticated diagnosis, protection and monitoring features through an SPI interface. A boost converter with integrated FET provides the overdrive voltage, allowing full control on the power-stages even for low battery voltage down to 4.75 V.
