AMT49702KLPATR

Overview

The AMT49702KLPATR is a dual DMOS full-bridge motor driver designed for pulse-width-modulated (PWM) control of low-voltage stepper motors and single or dual DC motors. It supports an operating voltage range from 3.5V to 15V and delivers output currents up to 1A per channel. The device is housed in a 16-pin eTSSOP package with an exposed pad, suitable for surface mount applications.

Feature Summary

• Dual DMOS full-bridge architecture for independent control of two motors
• Supports PWM control for precise speed and direction regulation
• Automotive-grade reliability compliant with AEC-Q100 standards

Applications

• Low-voltage stepper motor control systems
• Single DC motor drive circuits
• Dual DC motor drive configurations

Procurement Notes

Verify the specific suffix KLPATR against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement source provides valid traceability documentation for automotive-grade components. Cross-reference the part number with Allegro MicroSystems' current production status to avoid obsolete stock.

Selection Notes

Select this component when dual-channel motor control is required within a 15V supply limit. The 1A per channel rating suits small to medium load applications. The eTSSOP-16 package offers a compact footprint for space-constrained designs. Verify that the system's thermal management can handle the power dissipation associated with continuous 1A operation.

Part Context

This part belongs to the AMT49702 series, which features automotive qualification. It serves as a dedicated driver solution for integrating motor control functions into embedded systems without requiring external discrete power switches.

Replacement Considerations

Check for direct substitutes such as the AMT49702KLPTTR if different tape-and-reel packaging is required. Verify functional equivalence before swapping packages.
