Octal Serial Switch with SPI
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.
Product Details
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
