MC33880 | Octal Serial Switch with SPI

Overview

The NXP^® MC33880 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 MCU for pulse-width modulation (PWM) applications
Controls various inductive or incandescent loads by directly interfacing with a MCU
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

Designed to operate 5.5 V ≤ VPWR ≤ 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 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 Ohm at 25 °C typical
Short circuit detect and current limit with autoretry
Independent over-temperature protection
32-pin SOICW has pins 8, 9, 24, and 25 grounded for thermal performance
