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 over-temperature protection. |
