NUD3160DMT1

Overview

The NUD3160DMT1 is a single-channel industrial inductive load driver manufactured by onsemi. It integrates an N-channel power MOSFET and control circuitry to drive high-current loads such as solenoids, valves, and relays. The device operates with a supply voltage range of 4.5 V to 28 V and provides a peak output current capability of up to 2 A. It features low on-resistance for efficient power handling and includes built-in protection mechanisms against over-temperature conditions and reverse polarity connections.

Feature Summary

• Integrates a high-current N-channel MOSFET with dedicated gate drive logic for direct interface with microcontrollers or logic gates.
• Includes thermal shutdown protection to prevent device damage during sustained overload or excessive ambient temperature conditions.
• Supports reverse battery protection to safeguard the driver and connected load from incorrect power supply polarity.
• Designed for robust operation in industrial environments with wide operating temperature ranges.

Applications

• Industrial solenoid valve actuation
• Relay coil driving in automation systems
• Solenoid-based locking mechanisms
• General-purpose inductive load switching

Procurement Notes

Verify the exact suffix (e.g., T, G) when ordering, as it determines packaging and RoHS compliance status. Confirm the specific revision level of the datasheet matches your design requirements. Ensure the SC-74 package footprint aligns with your PCB layout constraints. Check for any recent product change notifications regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when a single-channel solution is required for loads drawing up to 2 A peak current. It is suitable for applications where space is limited due to its integrated MOSFET design compared to discrete solutions. Consider the thermal performance and heat dissipation capabilities of the SC-74 package for your specific enclosure environment. Verify that the input logic levels are compatible with your controlling microcontroller or PLC outputs.

Part Context

The NUD3160DMT1 belongs to onsemi's NUD31xx series of integrated inductive load drivers. This family is designed to simplify the design of circuits driving solenoids, relays, and other inductive loads by combining the power switch and driver IC into a single package. It serves as a cost-effective alternative to using separate MOSFETs and gate driver ICs in industrial control applications.

Replacement Considerations

NUD3160DMT1G is a verified equivalent part number offering identical functionality with RoHS compliance. Other members of the NUD31xx series may serve as functional substitutes if pin compatibility and electrical ratings match the specific application requirements.
