3 Description
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.
