Product details
Overview
MP6604AGV-Z from Monolithic Power Systems is a dual H-bridge motor driver IC designed for bipolar stepper and brushed DC motor control in industrial motion systems. It operates from 4.5V to 45V input voltage, delivers up to 2.5A per phase output current, features 150mΩ typical MOSFET on-resistance, and integrates OCP/OVP/UVLO/thermal shutdown with open-drain fault reporting. Used in precision stage lighting and 3D printer axis drivers.
For engineers reviewing the MP6604AGV-Z datasheet, MP6604AGV-Z pinout, MP6604AGV-Z application, or MP6604AGV-Z equivalent, this page provides verified functional identity, QFN-28 package mapping, confirmed dual H-bridge operation with independent IN/EN control, real-world timing parameters (t1–t4), and validated alternative part selection guidance.
Technical Context
The MP6604AGV-Z implements four independently controlled N-channel half-bridges-two per H-bridge-with automatic synchronous rectification to reduce body-diode conduction loss during inductive recirculation. Each output has dedicated AINx/BINx logic inputs and nAENx/nBENx enable pins, all with internal 100kΩ pull-down resistors.
It uses an internal charge pump (CPA/CPB/VCP) to generate ~VIN+5V for high-side gate drive and a 5V LDO (VREG) for low-side logic and gate drivers. Protection includes latchable over-current detection (3–4.5A threshold), 45V over-voltage lockout, 4.5V under-voltage lockout with 300mV hysteresis, and thermal shutdown at 165°C with 15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4.5V to 45V - supports wide-input industrial power rails including 12V, 24V, and 36V systems without external regulation. |
| IOUT Max | 2.5A per phase - enables direct driving of NEMA 17 stepper motors and 24V/2A brushed DC actuators. |
| RDS(ON)_HS / LS | 135–170mΩ / 150–185mΩ - minimizes conduction loss and thermal rise at full load in QFN-28 package. |
| OCP Threshold | 3–4.5A - configurable via external sense resistor; protects against shorted windings or stalled rotor conditions. |
| UVLO / OVP | 4.5V rising / 45V - ensures safe startup and prevents damage from transient overvoltage on main supply rail. |
| tOCP Deglitch | 1µs - rejects sub-microsecond current spikes while reliably triggering on sustained overloads. |
| nFAULT Type | Open-drain with external pull-up - allows wired-OR fault bus sharing across multiple drivers in multi-axis systems. |
Pinout & Package
MP6604AGV-Z is housed in a thermally enhanced QFN-28 (4mm × 5mm) package with exposed thermal pad. Pin numbering follows standard top-view orientation with Pin 1 at top-left corner adjacent to notch or mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 1, 8, 24) | Main power input | Accepts 4.5–45V; requires ≥100nF ceramic bypass per pin placed adjacent to IC for stable switching. |
| AOUT1 / AOUT2 / BOUT1 / BOUT2 (Pins 2, 4, 7, 5) | H-bridge output terminals | Drive motor phases directly; each pair forms one full H-bridge (A or B); rated for 48V abs max. |
| PGNDA / PGNDB (Pins 3, 6) | Power ground returns | Separate low-impedance paths for H-bridge A and B current return; must connect to thermal pad and ground plane. |
| AIN1/AIN2/BIN1/BIN2 (Pins 17, 16, 18, 19) | Phase control inputs | Direct logic-level H-bridge direction control; internal 100kΩ pull-down ensures safe Hi-Z default state. |
| nAEN1/nAEN2/nBEN1/nBEN2 (Pins 20, 21, 22, 23) | Output enable inputs | Active-low enables per MOSFET leg; decouples logic control from power path for precise sequencing and safety. |
| nSLEEP (Pin 14) | Low-power mode control | Pulling low disables charge pump and all outputs; draws only 0.9–10µA quiescent current in sleep mode. |
| nRESET (Pin 13) | Protection reset | Pulling low clears latched OCP/OVP/thermal faults and forces outputs into high-impedance state. |
| nFAULT (Pin 15) | Fault status indicator | Open-drain output pulled low on any protection event; requires external pull-up for system-level fault monitoring. |
| VREG (Pin 12) | Internal 5V regulator output | Powers low-side gate drivers and logic; requires 1µF X7R capacitor to GND rated ≥16V. |
| VCP (Pin 27) | Charge pump output | Provides ~VIN+5V for high-side gate drive; requires 1µF X7R capacitor to VIN rated ≥16V. |
| CPA / CPB (Pins 25, 26) | Charge pump flying capacitor terminals | Connect 100nF X7R ceramic capacitor between CPA and CPB; rated for full VIN range. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent H-bridge topology | Four half-bridges with separate IN/EN per output enable precise microstepping control and bidirectional torque management in stepper applications. |
| Automatic synchronous rectification | Reduces body-diode conduction loss during current recirculation, lowering junction temperature by up to 15°C at 2A continuous load. |
| Configurable over-current protection | OCP threshold set by external sense resistor; deglitch time fixed at 1µs to reject EMI-induced false triggers. |
| Integrated charge pump + LDO | Eliminates need for external high-side gate driver ICs or bootstrap diodes; simplifies PCB layout and reduces BOM count. |
| Thermal shutdown with hysteresis | Shuts down at 165°C and resumes at 150°C, preventing thermal cycling and enabling safe recovery after overload events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6600HG | Higher 4.5A rating but requires external bootstrap capacitors and lacks integrated VREG/VCP; no built-in OVP/UVLO. | Used in high-torque CNC steppers where external gate drivers are acceptable; less suitable for space-constrained embedded designs. | Select when peak current >2.5A is required and board area permits discrete gate drive components. |
| DRV8825 | Lower 2.2A rating, microstepping-only interface (no separate EN pins), no OVP, and 8–45V VIN range with tighter 8V min. | Common in hobbyist 3D printers; lacks independent enable per MOSFET and fault reporting capability. | Select for cost-sensitive, non-industrial applications where microstepping simplicity outweighs protection and flexibility needs. |
Compared with TB6600HG and DRV8825, MP6604AGV-Z uniquely combines independent per-leg enable control, integrated charge pump/LDO, comprehensive protection (OVP/UVLO/OCP/thermal), and QFN-28 thermal performance-making it optimal for industrial-grade motion control where reliability, layout simplicity, and diagnostic visibility are critical.

FAQ
What is the maximum continuous output current per channel for MP6604AGV-Z?
The MP6604AGV-Z supports up to 2.5A continuous output current per phase under thermal limits defined by its QFN-28 package (θJA = 40°C/W). At 24V input and TA = 25°C, this assumes adequate PCB copper area, thermal vias to inner layers, and ambient airflow. Derating applies above 85°C ambient.
Does MP6604AGV-Z require external bootstrap diodes or capacitors?
No. MP6604AGV-Z integrates a charge pump (CPA/CPB/VCP) and internal 5V LDO (VREG), eliminating the need for external bootstrap diodes or high-voltage floating supplies. Only three external capacitors are mandatory: 100nF between CPA–CPB, 1µF between VCP–VIN, and 1µF between VREG–GND.
How does the nFAULT pin behave during over-current events?
During over-current, over-voltage, or thermal faults, nFAULT is actively pulled low as an open-drain signal. It remains latched low until nRESET is asserted or VIN is cycled. An external pull-up resistor (typically 4.7kΩ to 5V or 3.3V) is required to establish a valid logic-high state when no fault is present.
Can MP6604AGV-Z drive unipolar stepper motors?
No. MP6604AGV-Z is configured exclusively for dual H-bridge (bipolar) operation, supporting only center-tapped or 4-wire bipolar stepper motors. It cannot configure individual windings as independent uni-directional drivers like unipolar drivers do, and lacks the necessary internal transistor topology for unipolar commutation.
What is the purpose of separate IN and EN pins for each output?
Separate AINx/BINx (direction) and nAENx/nBENx (enable) pins allow independent control of each MOSFET leg, enabling advanced drive modes such as fast/slow decay, synchronous rectification override, and precise current profiling-critical for reducing audible noise and improving torque linearity in stepper applications.
Is MP6604AGV-Z pin-compatible with MP6604AGF?
Yes. MP6604AGV-Z (QFN-28) and MP6604AGF-Z (TSSOP-28EP) share identical pin functions and electrical specifications. However, thermal performance differs: QFN-28 offers θJA = 40°C/W vs. TSSOP-28EP's 32°C/W, and PCB layout requirements (thermal pad soldering, via placement) are not interchangeable.
