Technical Data

Six Output Low Side Switch with

SPI and Parallel Input Control

33882

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).

SIX OUTPUT LOW SIDE SWITCH

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.
