Overview
The LMD18245T is a 3A, 55V DMOS full-bridge motor driver manufactured by Texas Instruments. It integrates control logic and power stages for bipolar stepper motors or brushed DC motors. The device operates within a supply voltage range of 12V to 55V and delivers an output current of 3A. It utilizes Bi-CMOS and DMOS technology in a TO-220-11 through-hole package. The component supports parallel interfaces and functions as a complete half-bridge configuration with two outputs.
Feature Summary
- Integrates full H-bridge control logic and power DMOS transistors
- Supports bidirectional drive for bipolar stepper and brushed DC motors
- Includes built-in thermal shutdown protection
Applications
- Bipolar stepper motor control systems
- Brushed DC motor drives
- Hydraulic pump actuators
- Linear actuator positioning
Procurement Notes
Verify RoHS compliance status as the standard LMD18245T may contain lead; confirm if LMD18245T/NOPB is required for lead-free specifications. Ensure the TO-220-11 package matches PCB footprint requirements. Check datasheet revisions for interface timing changes. Confirm active lifecycle status before finalizing design.
Selection Notes
Select this component for applications requiring integrated high-current motor driving without external discrete MOSFETs. Suitable for designs needing simple parallel control interfaces. Consider thermal management solutions due to power dissipation in the TO-220 package. Verify voltage headroom against the 55V maximum limit.
Part Context
Part of the LMD182xx series from Texas Instruments, designed for robust motor control. Related models include the LMD18200T (half-bridge) and LMD18201T. The LMD18245T specifically provides full-bridge capability for more complex motor configurations compared to half-bridge variants.
Replacement Considerations
- LMD18245T/NOPB
FAQ
What type of motor control does the LMD18245T support?
It supports bipolar stepper motors and brushed DC motors using a full-bridge configuration.
Is the LMD18245T lead-free?
The standard LMD18245T contains lead. The LMD18245T/NOPB variant is RoHS compliant and lead-free.
