Document Number: MC33882 Freescale Semiconductor Rev. 11.0, 11/2014 Technical Data Six Output Low-side Switch with 33882 SPI and Parallel Input Control 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 SIX OUTPUT LOW-SIDE SWITCH 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). 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 EK SUFFIX EP SUFFIX VW SUFFIX device has multiple monitoring and protection features, including low (PB-FREE) (PB-FREE) (PB-FREE) 98ASA00706D 98ARL10543D standby current, fault status reporting, internal 52 V clamp on each 98ASH70693A 32-PIN QFN 32-PIN SOICW 30-PIN HSOP output, output specific diagnostics, and protective shutdown. Additionally, it has a mode select pin affording a dual means of input control.
