Six Output Low-side Switch with
SPI and Parallel Input Control
33882
The 33882 is a smart 6 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
(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.
Additionally, it has a mode select pin affording a dual means of input
control.
