MC33470DWR2G

Overview

The MC33470DWR2G is a dual-channel, high-side driver integrated circuit designed for automotive applications. It features two independent output channels capable of driving inductive loads such as solenoids and lamps. The device includes built-in protection mechanisms against over-current, short-circuit to ground, and open-load conditions. It operates within a wide supply voltage range and supports PWM dimming control for precise load management. The component is housed in a TSSOP-16 package, ensuring compact integration into vehicle electronic control units while maintaining robust thermal performance under continuous operation.

Feature Summary

• Dual independent high-side output channels for simultaneous load control
• Integrated diagnostic feedback for fault detection including open-load and short-circuit states
• Built-in thermal shutdown and over-current protection for enhanced reliability

Applications

• Automotive exterior lighting systems
• Interior ambient lighting control
• Solenoid actuation in vehicle modules
• Fan and pump motor drive circuits

Procurement Notes

Verify the specific suffix 'DWR2G' corresponds to the tape-and-reel packaging variant when sourcing. Confirm that the ordering code matches the exact pinout and thermal pad configuration required by your PCB layout. Ensure compatibility with your system's logic voltage levels before finalizing procurement. Cross-reference the manufacturer's latest datasheet revision to confirm any updates to electrical characteristics or recommended operating conditions.

Selection Notes

Select this component when dual-channel high-side switching with integrated diagnostics is required. It is suitable for designs needing robust protection against common automotive electrical faults. Consider the TSSOP-16 package size if space constraints are critical. Ensure the application does not exceed the maximum current ratings per channel. Verify that the PWM frequency requirements align with the device's switching capabilities.

Part Context

This part belongs to onsemi's family of automotive-grade high-side drivers. It is engineered to meet stringent automotive reliability standards. The device complements other single-channel drivers by offering dual functionality in a compact form factor. It is commonly used in body control modules and lighting control units where space and protection features are prioritized.

Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify that alternative parts offer equivalent current ratings and protection features. Ensure the substitute component meets the same automotive qualification standards. Confirm package dimensions match existing footprints to avoid rework.
