The L9908 from STMicroelectronics is a 3 Phase Motor Gate Driver that is specifically designed for controlling 6 N-channel FETs for brushless motors in automotive applications. This motor driver has an input voltage of 4.5-75 V that supports working in single (12 V), double (24 V), and 48 V battery applications. It consists of three differential high accuracy current monitors for ground referred current measurements and three real-time phase voltage monitor channels. This AEC-Q100 qualified motor driver has a dedicated combination of regulators, charge pumps, and bootstrap circuits that allows it to operate in passenger, commercial or hybrid vehicles. It consists of ground-loss detection, over-voltage and under-voltage detection on the power supply pins and FET-driver supply, system-clock monitoring, SPI window watchdog, and a fault-status flag features. 

The L9908 can be also used in traction inverters for mild-hybrid internal combustion engine (ICE) vehicles and 48 V full-electric city cars. It is available in a surface-mount package that measures 7 x 7 x 1 mm and is ideal for Electronic Power Steering (EPS), HVAC blowers, engine cooling fans, electronic brake booster, EWP, EFP, and EOP applications.
