The 33880 device is an eight-output hardware-configurable high side/low-side switch with 8-bit serial input control. Two of the outputs can be controlled directly via microcontroller for Pulse Width Modulation (PWM) applications.

The 33880 controls various inductive or incandescent loads by directly interfacing with a microcontroller.

The circuits innovative monitoring and protection features include very low standby currents, “cascadable” fault reporting, internal 40 V output clamping for low-side configurations, internal -20 V output clamping for high-side configurations, output-specific diagnostics, and independent shutdown of outputs.
