Monolithic Power Systems Inc. MP6613GV-P

Overview

MP6613GV-P from Monolithic Power Systems is a single H-bridge motor driver IC designed for brushed DC and bipolar stepper motor control in industrial motion systems. It operates from 4.5V to 45V input voltage, delivers up to 5A continuous output current (dependent on thermal design), features 75mΩ typical R_DS(ON) per MOSFET, integrated over-current/over-voltage/under-voltage/thermal protection, and supports three configurable control modes via INM[1:0] pins - used in laser printers and textile machinery.

For engineers reviewing the MP6613GV-P datasheet, MP6613GV-P pinout, MP6613GV-P application, or MP6613GV-P equivalent, this page provides verified electrical specifications, QFN-28 package layout details, functional mode mapping, fault reporting behavior, and real-world implementation guidance for motor drive stage design.

Technical Context

The MP6613GV-P integrates four N-channel power MOSFETs in a full H-bridge topology with independent high-side and low-side gate drivers. Its charge pump (VCP) generates >VIN+5V for HS-FET gate drive, while VREG supplies 5V for logic and LS-FET control. Automatic synchronous rectification reduces body-diode conduction loss during inductive flyback.

Input interface configuration is determined by INM0 and INM1 pins, enabling ENA/PWM, PHASE/ENBL, or HS/LS control schemes. Protection circuitry includes latched OCP (6–9A trip), OVP (45–48V threshold), UVLO (4.5V rising), and thermal shutdown (165°C with 15°C hysteresis), all signaled via open-drain nFAULT.

Key Specifications

Pinout & Package

MP6613GV-P is housed in a thermally enhanced QFN-28 (4mm × 5mm) package with exposed thermal pad. The 28-pin layout supports dual VIN/PGND/GND pins for low-impedance power routing and parallel OUT1/OUT2 connections to handle high-current motor paths.

FAQ

What is the maximum allowable ambient temperature for continuous 5A operation?

At 25°C ambient, the QFN-28 package supports up to 3.125W dissipation. With proper PCB copper area (≥4 cm² thermal pad + 6+ thermal vias), MP6613GV-P sustains 5A continuously up to 70°C ambient. Derating begins above that point per θ_JA=40°C/W; full 5A is not guaranteed above 85°C without forced airflow.

How does automatic synchronous rectification improve efficiency?

When both HS and LS FETs are off, the MP6613GV-P senses V_OUTx < 0V or > VIN and turns on the appropriate FET to conduct recirculating current. This replaces ~1.1V body-diode drop with <0.5V channel conduction, cutting freewheeling losses by ~50% compared to diode-only recovery.

Can INM[1:0] be changed dynamically during operation?

No. INM0 and INM1 are sampled at power-up or after nRESET assertion and latched. Changing them mid-operation has no effect until the next reset cycle. For runtime mode switching, use external logic to translate control signals into the selected mode's pin protocol.

What external capacitors are mandatory for stable operation?

Four capacitors are required: (1) ≥100nF X7R ceramic on each VIN pin to PGND, (2) 1µF X7R on VREG to GND, (3) 1µF X7R on VCP to VIN, and (4) 100nF X7R between CPA and CPB. All must be rated ≥16V; bulk electrolytic on VIN is recommended for high-impedance supplies.

Is nFAULT asserted during UVLO conditions?

Yes. Input under-voltage lockout (UVLO) triggers nFAULT assertion along with OCP, OVP, and thermal shutdown. The pin remains low until VIN rises above 4.5V + 300mV hysteresis and the device completes internal reset - no nRESET pulse is needed to clear UVLO-induced faults.

Does MP6613GV-P support microstepping?

Not directly. It drives full-step or half-step bipolar steppers via external indexer or MCU-generated phase sequencing. Its three control modes allow clean commutation timing, but microstepping resolution depends entirely on upstream PWM duty-cycle or phase voltage control - the IC itself performs only full-H-bridge switching.

What is the minimum dead time between HS and LS FET switching?

The internal dead-time is fixed at 80ns, preventing shoot-through during PWM transitions. This value is non-adjustable and applies across all input modes and operating conditions, ensuring safe commutation even at 20kHz switching frequencies.
