Advance Information
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 terminal affording 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
• Load Dump Robust (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 per Output (25°C) at 13 V VPWR
• SPI Operation Guaranteed to 2.0 MHz
