MC33882: 6 Output Switch, SPI, Parallel Input Control

Overview

The NXP^® MC33882 is a six-output, low side switch that controls system loads up to 1.0A. The six outputs can be controlled via both serial peripheral interface (SPI) and parallel input control, ideal for fault tolerant system applications.

Interfaces directly with industry standard MCUs via SPI to control both inductive and incandescent loads
Outputs are configured as open drain power MOSFETs incorporating internal dynamic clamping and current limiting
Monitoring and protection features, including low standby current, fault status reporting, internal 52V clamp on each output, output specific diagnostics, and protective shutdown
Mode select pin offers a dual means of input control

Features

Outputs clamped for switching inductive loads

Very low operational bias currents (< 2.0 mA)

CMOS input logic compatible with 5.0 V logic levels

Robust load dump (60 V transient at VPWR on OUT0 – OUT5)

Daisy chain operation of multiple devices possible

Switch outputs can be paralleled for higher currents

RDS(ON) of 0.4 Ω per output (25 °C) at 13 V VPWR

SPI operation guaranteed to 2.0 MHz
