数据： DRV3245Q-Q1 3-Phase Automotive Gate Driver Unit (GDU) With High Performance Sensing, Protection and Diagnostics 数据表

描述

The DRV3245Q-Q1 device is a FET gate driver IC for three-phase motor-driveapplications designed according to the applicable requirements of ISO 26262 for functional safetyapplications. The device provides three half-bridge drivers each capable of driving a high-side andlow-side N-channel MOSFET while also providing sophisticated protection and monitoring of the FETs.A charge-pump driver enables 100% duty cycle and supports low battery voltages during cold-crankoperation. The integration of current-sense amplifiers, integrated phase comparators, and SPI-basedconfiguration of the driver and its peripherals enable reduction of the bill of materials (BOM) andspace on the printed circuit board (PCB) because of the elimination of most external and passivecomponents.

The DRV3245Q-Q1 device also integrates diagnostics and protection for eachinternal block and provides support for common system diagnostic checks each of which can beinstantiated and reported through SPI. This flexibility of the integrated features allows thedevice to integrate seamlessly into a variety of safety architectures.
