Advance Information
Configurable Octal Serial Switch
with Open Load Detect Current
Disable
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 overtemperature protection.
