STDRIVE121/141/181 Half-Bridge Gate Drivers

STMicroelectronics STDRIVE121/141/181 Half-Bridge Gate Drivers are dual (STDRIVE121), quad (STDRIVE141), or octal (STDRIVE181) half-bridge gate drivers dedicated to control four (STDRIVE121), eight (STDRIVE141), or sixteen (STDRIVE181) N-Channel MOSFETs. An SPI frame configures and controls half-bridges during active mode. SPI status registers provide high-level diagnostic information, including supply-voltage monitoring, charge-pump voltage monitoring, temperature warnings, and overtemperature shutdown.
