NUD3112DMT1G

Overview

The NUD3112DMT1G is an integrated dual inductive load driver manufactured by onsemi. It features two independent drivers, each capable of sourcing or sinking up to 150 mA of output current. The device operates within a supply voltage range of 4.5 V to 28 V and supports logic-level inputs compatible with standard microcontrollers. Designed for surface-mount applications, it utilizes a compact SC-74-6 package. The component includes internal protection mechanisms such as ESD protection and thermal shutdown, ensuring reliable operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates dual high-current drivers for simultaneous control of multiple inductive loads without external components
• Features built-in ESD protection and thermal shutdown for enhanced system reliability
• Accepts direct logic-level input signals from microcontrollers or logic gates

Applications

• Automotive relay switching systems
• Solenoid and valve actuation circuits
• Industrial control panel load management

Procurement Notes

Verify the specific suffix 'DMT1G' to confirm the dual-channel configuration and tape-and-reel packaging format. Ensure compatibility with SC-74-6 footprint requirements during PCB layout. Confirm RoHS compliance status if required by regional regulations. Cross-reference the manufacturer part number against official distributor catalogs to avoid confusion with single-channel variants in the same series.

Selection Notes

Select this component when dual independent control of inductive loads is required in a minimal footprint. It is suitable for designs needing high peak current capability for fast switching speeds. Consider the operating voltage range and thermal performance constraints relative to the expected load duty cycle. Verify that the logic input levels match the driving source voltage.
