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
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.

SWITCH WITH SERIAL
PERIPHERAL INTERFACE
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 2.0 A) to Drive Incandescent
Lamps
• Output Voltage Clamp Is +45 V (Typical) (Low-Side Drive) and -20 V
(Typical) (High-Side Drive) During Inductive Switching
• Internal Reverse Battery Protection on VPWR
• Loss of Ground or Supply Will Not Energize Loads or Damage IC
• Maximum 5.0 µA IPWR Standby Current at 13 V VPWR up to 95°C
• RDS(ON) of 0.55 at 25°C Typical
• Short Circuit Detect and Current Limit with Automatic Retry
• Independent Overtemperature Protection
• 32-Pin SOIC Has Pins 8, 9, 24, and 25 Grounded for Thermal
Performance
