Freescale Semiconductor

Technical Data

Configurable Octal Serial Switch

with Serial Peripheral Interface

I/O

33880

The 33880 device is an 8-output hardware configurable high side/

low side switch with 8-bit serial input control using the serial peripheral

interface (SPI). Two of the outputs can be controlled directly via

microcontroller for pulse-width modulation (PWM) applications.

HIGH/LOW SIDE SWITCH

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, “cascadable” fault reporting, internal 40 V

output clamping for low side configurations, internal -20 V output

clamping for high side configurations, output specific diagnostics, and

independent shutdown of outputs.

Features

32-PIN SOICW

• Designed to operate 5.5 V < V_PWR< 24.5 V

• 8-bit SPI for control and fault reporting, 3.3/5.0 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

• Loss of ground or supply will not energize loads or damage IC

• Maximum 5.0 μA I_PWRstandby current at 13 V V_PWRup to 95 °C

• R_DS(ON)of 0.55 Ω at 25 °C typical
