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 is a
bidirectional full-bridge driver with PWM or phaseenable
control. Designed in a BiCMOS high-power
process technology node, this monolithic family
of devices 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. This family provides an identical pin
function with scalable RON (current capability) to
support different loads.
The devices integrate an 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 overtemperature.
Fault conditions are indicated on the
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.
