Advance Information
33880
Configurable Octal Serial Switch
with Serial Peripheral Interface I/O
The 33880 device is an eight-output hardware configurable high-side/low-
side switch with 8-bit serial input control. Two of the outputs may be controlled
directly via microprocessor for PWM applications. The 33880 incorporates
SMARTMOStechnology, with CMOS logic, bipolar/MOS analog circuitry,
and DMOS power MOSFETs. The 33880 controls various inductive or
incandescent loads by directly interfacing with a microcontroller. The circuit’s
innovative monitoring and protection features include very low standby
currents, cascade fault reporting, output-specific diagnostics, and
independent shutdown of output.
