3 Description
The DRV3245Q-Q1 device is a FET gate driver
IC for three-phase motor-drive applications designed
according to the applicable requirements of ISO
26262 for functional safety applications. The device
provides three half-bridge drivers each capable
of driving a high-side and low-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-crank operation. The
integration of current-sense amplifiers, integrated
phase comparators, and SPI-based configuration of
the driver and its peripherals enable reduction of the
bill of materials (BOM) and space on the printed
circuit board (PCB) because of the elimination of most
external and passive components.
The DRV3245Q-Q1 device also integrates diagnostics
and protection for each internal block and provides
support for common system diagnostic checks each
of which can be instantiated and reported through
SPI. This flexibility of the integrated features allows
the device to integrate seamlessly into a variety of
safety architectures.
