33880
Advance Information
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
SMARTMOS
technology, with CMOS logic, bipolar/MOS analog circuitry,
and DMOS power MOSFETs. The 33880 controls various inductive or
incandescent loads by directly interfacing with a micro controller. The circuit’s
innovative monitoring and protection features include: very low standby
currents; cascade fault reporting; internal +40 V clamp voltage for low side
configuration; -20 V high side configuration; output specific diagnostics; and
independent shutdown of output.
Features
Designed to operate 5.5 V < VPWR < 24.5 V
8-Bit SPI for Control and Fault Reporting, 3.3 V/5.0 V Compatible
Outputs are current limited (0.8 A to 2 A) to Drive Incandescent Lamps
Output voltage Clamp, +45 V (low side) and -20 V (high side) During
Inductive Switching
Internal Reverse Battery Protection on VPWR
Loss of Ground or Supply Will Not Energize Loads or Damage IC
