The DRV814x-Q1 family of devices is a fully integrated half-bridge driver intended for a wide range of automotive applications. 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 half-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. DRV8143 and DRV8145 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. DRV8144 is available only in two variants: SPI(S) and HW(H). The SPI interface variants offer more flexibility in device configuration and fault observability.
