Overview
The MDC3105LT1G is an integrated relay and inductive load driver manufactured by onsemi. It operates with a maximum load voltage of 6V and delivers a peak output current of 500mA. The device utilizes a bipolar output configuration within a surface-mount SOT-23-3 package. Designed for low-voltage applications, it features a single output channel optimized for driving small relays and solenoids efficiently.
Feature Summary
- Integrated monolithic circuit block designed specifically for relay and inductive load control
- Bipolar output topology suitable for driving low-voltage electromagnetic actuators
- Compact surface-mount packaging facilitates automated assembly in space-constrained designs
Applications
- Low-voltage automotive relay switching systems
- Solenoid drivers in consumer electronic appliances
- Industrial control modules requiring compact inductive load management
Procurement Notes
Verify the specific suffix 'LT1G' to confirm lead-free compliance and tape-and-reel packaging format. Confirm that the component status is active or obsolete as required by your supply chain strategy. Ensure the 6V load voltage rating aligns with your system's power rails before procurement.
Selection Notes
Select this component when a single-channel, low-side bipolar driver is needed for loads up to 6V and 500mA. It is appropriate for applications where board space is limited due to its SOT-23 form factor. Consider alternative high-voltage drivers if the target load exceeds 6V or requires higher current capacity than 500mA.
Part Context
This part belongs to the MDC3105 series of integrated inductive load drivers from onsemi. It serves as a specialized solution for managing small electromagnetic loads in low-voltage environments. The series includes variants such as NUD3105, offering different pinouts or configurations for similar functional requirements.
Replacement Considerations
Publicly confirmed substitutes include NUD3105LT1 and NUD3105D. Verify pin compatibility and electrical ratings against the original datasheet before substitution.
