33880

Configurable Octal Serial Switch

with Serial Peripheral Interface I/O

CONFIGURABLE OCTAL SERIAL

SWITCH WITH SERIAL

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 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.

PERIPHERAL INTERFACE

Features

• Designed to Operate 5.5 V < V_PWR< 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 V_PWR
