 Descriptions The 

SC77708Q is a Multi-MOSFET driver IC dedicated to control up to 16 N-channel MOSFETs. It includes 8 half-bridges 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 the SC77708Q and to control the half bridges. It also allows the read out of the status registers for diagnostic purpose. The SC77708Q offers a wide range of diagnostic features such as the monitoring of the supply voltage, the charge pump voltage, temperature warning and over-temperature shutdown. Each gate driver monitors independently its external MOSFET drain-source voltage for fault conditions. The device is housed in a VQFN-48 with exposed pad supporting lead tip inspection. The package provides a good thermal performance and minimizes the required PCB space.
