3 Description
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.
