Technical Data

Document Number: MC33879

Rev. 11.0, 7/2016

Configurable octal serial switch with

open load detect current disable

The 33879 device is an 8-output hardware configurable, high-side/low-side

switch with 16-bit serial input control using the serial peripheral interface (SPI).

Two of the outputs may be controlled directly via a microcontroller for pulse-

width modulation (PWM) applications. The 33879 incorporates SMARTMOS

technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power

MOSFETs. The 33879 controls various inductive, incandescent, or LED loads by

directly interfacing with a microcontroller. The circuit’s innovative monitoring and

protection features include very low standby currents, cascade fault reporting,

internal + 45 V clamp voltage for low-side configuration, - 20 V high-side

configuration, output specific diagnostics, and independent overtemperature

protection.
