L99MH94/L99MH92 Half-Bridge Pre-Drivers

STMicroelectronics L99MH94/L99MH92 Quad and Dual Half-Bridge Pre-Drivers are dedicated to controlling up to eight N-channel MOSFETs. It is intended for DC motor control applications such as automotive power seat control or other applications. A 24-bit serial peripheral interface (SPI) is used to configure and control the eight half-bridges. SPI status registers provide high-level diagnostic information, including supply-voltage monitoring, charge-pump voltage monitoring, temperature warnings, and overtemperature shutdown.
