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.
