The 33879 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.
