MTS2916A-LGC1

Overview

The MTS2916A-LGC1 is a CMOS dual full-bridge PWM motor driver designed to drive bipolar stepper motor coils or bidirectional DC motors. It features two independent H-bridge outputs capable of sustaining 40V supply voltage and delivering up to 750mA continuous current per channel, with a maximum output current rating of 1A. The device operates within a temperature range of -40°C to +105°C and utilizes internal fixed T_OFF time PWM current control. Logic inputs are LS-TTL compatible with pull-up resistors, and the unit includes internal protection diodes, thermal shutdown, and under-voltage lockout.

Feature Summary

• Supports full, half, and micro-stepping operations through integrated PWM current control and logic input configuration.
• Optimized H-bridge outputs provide low saturation voltage drop for efficient power delivery.
• Includes comprehensive internal protection mechanisms such as thermal shutdown and under-voltage lockout.

Applications

• Bipolar stepper motor drive systems
• Bidirectional DC motor control applications
• Embedded motion control circuits

Procurement Notes

Verify the specific suffix LGC1 against official Microchip documentation to confirm package type and material specifications. Ensure compatibility with system voltage requirements not exceeding 40V. Confirm that the operating temperature range aligns with environmental conditions. Cross-reference pin assignments with the official datasheet to prevent interface mismatches during integration.

Selection Notes

Select this component when driving bipolar stepper motors or bidirectional DC loads requiring independent H-bridge control. The internal PWM controller simplifies current regulation compared to discrete solutions. Verify that the required continuous current does not exceed 750mA per bridge. Consider the thermal management capabilities given the internal shutdown feature and operating temperature limits.
