Overview
The MC33988CPNA is a single-package automotive power switch integrating four high-side MOSFETs and eight low-side drivers. It features a 16-bit SPI interface for programming, control, and diagnostics. The device supports PWM control via parallel inputs for high sides and direct inputs for low sides. It provides comprehensive protection including overcurrent, overtemperature, and reverse polarity protection.
Feature Summary
- Integrates dual 10 mΩ and dual 40 mΩ high-side switches with octal low-side drivers
- Enables precise load management through 16-bit serial peripheral interface communication
- Supports pulse-width modulation control via dedicated parallel input lines
- Includes advanced diagnostic reporting for fault detection and system monitoring
Applications
- Automotive lighting systems
- Relay driver circuits
- LED load control applications
Procurement Notes
Verify the specific suffix CPNA to confirm package type and temperature range specifications. Ensure compatibility with existing 16-bit SPI communication protocols in your design. Confirm that the integrated protection features meet your system's safety requirements. Check for any specific ordering variations or revision levels available from authorized distributors.
Selection Notes
Select this component when a combined high-side and low-side switching solution is required in a compact form factor. It is suitable for applications needing independent control of multiple loads with detailed diagnostic feedback. Consider the thermal performance and current ratings relative to your specific load requirements.
Part Context
This part belongs to NXP's portfolio of automotive power switches designed for robust performance in harsh environments. It complements other motor driver and load switch solutions by providing versatile switching capabilities within a single integrated circuit package for efficient board space utilization.
Replacement Considerations
Check for functional equivalents such as the MC33888 series which offers similar high-side and low-side integration. Verify pinout compatibility and SPI command set alignment before substitution.
