Three half bridges for 1.6A load (ron 800mΩ)
One high-side driver for 6A load (ran 100mΩ)
Very low current consumption in standby mode (Is <6μA, typ. Tj ≤ 85°C)
Serial Peripheral Interface (SPI) to microcontroller
All outputs short circuit protected
Current monitor output for full bridge and high-side driver
All outputs over temperature protected
Open load diagnostic for all outputs
Overload diagnostic for all outputs

Features
Low current consumption in standby mode
SPI interface for easy control
Short circuit protection for all outputs
