The DRV824x-Q1 family of devices is a fully integrated H-bridge driver intended for a wide range of automotive applications. The device can be configured as a single full-bridge driver or as two independent half-bridge drivers. Designed in a BiCMOS high power process technology node, this monolithic family of devices in a power package offer excellent power handling and thermal capability while providing compact package size, ease of layout, EMI control, accurate current sense, robustness, and diagnostic capability. This family provides an identical pin function with scalable RON (current capability) to support different loads.

The devices integrate a N-channel H-bridge, charge pump regulator, high-side current sensing with regulation, current proportional output, and protection circuitry. A low-power sleep mode is provided to achieve low quiescent current. The devices offer voltage monitoring and load diagnostics as well as protection features against over current and over temperature. Fault conditions are indicated on nFAULT pin. The devices are available in three variants - hardwired interface: HW (H) and two SPI interface variants: SPI(P) and SPI(S), with SPI (P) for externally supplied logic supply and SPI (S) for internally generated logic supply. The SPI interface variants offer more flexibility in device configuration and fault observability.
