be controlled directly via a 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 over-temperature protection.
