3 Description
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.
