MP6612DGF-P

Overview

The MP6612DGF-P is a high-current H-Bridge DC motor driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 4 V to 40 V and delivers up to 5 A of continuous output current. The device integrates an internal charge pump for gate drive generation, enabling support for 100% duty cycle operation. Control inputs utilize ENBL and DIR logic signals. Key electrical parameters include a maximum power dissipation of 3.125 W, a quiescent current of 1 uA in standby mode, and a switching frequency of 100 kHz. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates a full H-bridge with internal charge pump supporting 100% duty cycle
• Provides proportional current sensing via internal CS circuit without external shunt resistors
• Features comprehensive protection including overcurrent, overvoltage, undervoltage lockout, and overtemperature shutdown
• Utilizes ENBL and DIR logic inputs for simplified directional and enable control

Applications

• Reversible DC motor control systems
• Stepper motor winding drivers
• General purpose load driving applications

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management design accounts for the TSSOP-20EP package characteristics and specified power dissipation limits under expected load conditions.

Selection Notes

Select this component for applications requiring bidirectional motor control with integrated current regulation. The ENBL/DIR interface simplifies logic control compared to standard IN1/IN2 variants. Consider the low standby current for battery-operated systems. Verify that the 40V maximum rating aligns with the system's peak voltage transients.

Part Context

This part belongs to the MP6612 series of motor drivers. The 'D' variant specifically denotes the use of Enable (ENBL) and Direction (DIR) control pins, distinguishing it from the standard MP6612 which uses IN1 and IN2 inputs. Both variants share identical electrical performance and internal architecture.

Replacement Considerations

MP6612GF-Z serves as a direct functional equivalent within the same product family.
