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.
