Six-Output Low-Side Switch
with SPI and Parallel Input
Control
The 33882 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 33882 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, output-specific diagnostics, and protective shutdown. In
addition, it has a mode select pin affording a dual means of input
control.
