33879

33879A

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

low-side switch with 16-bit serial input control. Two of the outputs may

be controlled directly via microprocessor for 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.
