The DRV8163-Q1 is a wide-voltage, high-power fully integrated half-bridge driver for 24V and 48V automotive applications. Designed in a BiCMOS high-power process technology node, this device in a power package offers excellent power handling and thermal capability while providing compact package size, ease of layout, EMI control, accurate current sense, robustness, and diagnostic capability.
The device integrates a N-channel half-bridge, charge pump, high-side current sensing with regulation, current proportional output, and protection circuitry. The integrated sensing uses a current mirror, removing the need for shunt resistors, saving board area, and reducing system cost. A low-power sleep mode is provided to achieve low quiescent current.
The device offers voltage monitoring and load diagnostics, as well as protection features against overcurrent and overtemperature. Fault conditions are indicated on the nFAULT pin. The device is available in two variants: HW interface and SPI. The SPI variant offers more flexibility in device configuration and fault observability.
