Overview
The MC33882 is a smart six output low
side switch able to control system loads
up to 1.0 A. The six outputs can be
controlled via both serial peripheral
interface (SPI) and parallel input control,
making the device attractive for fault
tolerant system applications. There are
two additional 30 mA low side switches
with SPI diagnostic reporting (with parallel
input control only).
The MC33882 is designed to interface
directly with industry standard
microcontrollers via SPI to control both
inductive and incandescent loads.
Outputs are configured as open-drain
power MOSFETs incorporating internal
dynamic clamping and current limiting.
The device has multiple monitoring and
protection features, including low standby
current, fault status reporting, internal
52 V clamp on each output, outputspecific diagnostics, and protective
shutdown. In addition, it has a mode
select terminal affording a dual means of
input control.
