MC33288DDHR2

Overview

The MC33288DDHR2 is a high-side power driver manufactured by NXP USA Inc., designed for general-purpose load switching applications. It features two independent channels with a 1:1 input-to-output ratio, supporting load voltages from 8V to 35V and delivering a maximum output current of 8A per channel. The device incorporates an on/off interface and exhibits a typical on-resistance of 20mΩ. Integrated fault protection mechanisms include open-load detection and over-temperature shutdown. Operating within a junction temperature range of -40°C to 150°C, it is housed in a 20-HSOP package with an exposed pad for surface-mount installation.

Feature Summary

• High-side configuration with dual independent channels for versatile load control
• Integrated diagnostic capabilities including open-load detection and thermal protection
• Low on-resistance design for efficient power delivery in automotive environments

Applications

• Automotive lighting systems
• General-purpose load switching in vehicle electronics
• High-side driver circuits requiring robust fault protection

Procurement Notes

Verify component authenticity through authorized NXP distributors or direct channels. Confirm the specific suffix 'R2' indicates tape-and-reel packaging if required for automated assembly. Check for obsolete status notifications as this series may have been discontinued. Ensure compliance with project-specific environmental regulations regarding RoHS exemptions if applicable.

Selection Notes

Select this component when high-side switching with integrated diagnostics is required. The 8A current capability suits moderate-power loads. Verify that the 20-HSOP package fits the PCB layout constraints. Consider the operating temperature range suitability for the intended environment. Evaluate if the specific fault protection features meet system safety requirements.
