STMicroelectronics L9907 Automotive FET Drivers

STMicroelectronics L9907 Automotive FET Drivers are smart power devices with advanced BCD-6s technology. The L9907 can drive all PowerMOS transistors for 3-phase BLDC motor applications. The circuit is suitable to operate in environments with high supply voltage like a double battery. Supply-related pins are capable of withstanding up to 90V and the device can control the six pre-driver channels independently.

Features

Supply voltage from 6V to 54V for working in single (12V systems), double (24V systems), and 48V battery applications
The device can withstand -7V to 90V at the FET high-side driver pins
2-differential current sense amplifiers:
- Output offset selectable via SPI (0.2*V_CC offset for ground shunt resistors connection, 0.5*V_CC offset for phase shunt resistors connection)
- All the amplifier gain factors are programmable (10, 30, 50, 100)
