Configurable Octal Serial Switch
with Open Load Detect Current
Disable
The 33879 device is an 8-output hardware-configurable, high-side
ow-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.
