MP6612DGF-Z

Overview

The MP6612DGF-Z is a monolithic 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 features ENBL and DIR logic inputs for control, distinguishing it from the standard MP6612 which uses IN1/IN2. Key electrical parameters include a quiescent current of 1 uA in standby mode and a switching frequency of 100 kHz. It supports bidirectional motor control with low static current during braking. The component is housed in a TSSOP-20EP package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrated H-bridge architecture with internal charge pump enabling 100% duty cycle operation without external bootstrap components.
• Built-in current sensing circuitry provides a voltage proportional to load current, facilitating precise overcurrent protection and regulation.
• Comprehensive protection suite includes overcurrent (OCP), overvoltage (OVP), undervoltage lockout (UVLO), and overtemperature (OTP) shutdowns.
• Configurable logic interface utilizing separate Enable (ENBL) and Direction (DIR) pins for simplified system control.

Applications

• Reversible DC motor control in industrial automation systems
• Driver circuits for bipolar stepper motor windings
• High-current load switching applications requiring bidirectional flow

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status as per manufacturer declarations. Confirm the 'D' variant designation corresponds to the ENBL/DIR input configuration rather than the standard IN1/IN2 logic. Ensure thermal management strategies account for the TSSOP-20EP package's power dissipation capabilities under maximum load conditions.

Selection Notes

Select this component when bidirectional drive capability and integrated current sensing are required within a compact surface-mount footprint. The ENBL/DIR interface simplifies microcontroller interfacing compared to dual-input variants. Consider the 4V minimum operating voltage for compatibility with single-cell lithium or multi-cell battery architectures.

Part Context

This part belongs to the MP6612 series of high-current H-bridge drivers. It shares core power stage characteristics with the MP6612 but differs in control logic pinout. The series is designed for applications demanding robust motor control with minimal external component count. The GF-Z suffix denotes the specific tape-and-reel packaging and environmental compliance.

Replacement Considerations

MP6612GF-Z serves as the functional equivalent with identical electrical performance but utilizes IN1/IN2 logic inputs instead of ENBL/DIR. Verify pin compatibility before substitution due to the control interface difference. No other direct cross-model replacements are documented in the provided data.
