Product details
Overview
MP6604CGV-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, features integrated 150mΩ RDS(ON) N-channel MOSFETs per half-bridge, and includes over-current, over-voltage, under-voltage, and thermal shutdown protection. It targets stage lighting and 3D printer motion subsystems.
For engineers reviewing the MP6604CGV-Z datasheet, MP6604CGV-Z pinout, MP6604CGV-Z application, or MP6604CGV-Z equivalent, this page provides verified technical context, QFN-28 package mapping, HS/LS control interface details, fault reporting behavior, and real-world motor drive constraints - all derived from the official MP6604C Rev. 1.1 datasheet.
Technical Context
The MP6604CGV-Z integrates eight N-channel power MOSFETs arranged as four independently controllable half-H-bridges, enabling dual full-H-bridge (stepper) or quad half-H-bridge (solenoid/DC motor) configurations. Its gate drivers use charge-pump-based high-side biasing (VCP ≥ VIN + 5V) and internal 5V LDO (VREG) for low-side control.
Protection logic includes latched over-current detection with 1µs deglitch time, 45V over-voltage lockout with 300mV hysteresis, and thermal shutdown at 165°C with 15°C hysteresis. Fault status is reported via open-drain nFAULT, requiring external pull-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4.5V to 45V - supports 12V/24V/36V industrial rails and tolerates transient spikes up to 48V absolute max. |
| Output Current | 2.5A continuous per phase - derated by ambient temperature and PCB copper area; validated at TA = 25°C with proper thermal layout. |
| RDS(ON) | 150mΩ typical per MOSFET - reduces conduction loss to ≤940mW per FET at 2.5A, critical for thermally constrained designs. |
| OCP Threshold | 3A to 4.5A - programmable via external sense resistor; trips after 1µs deglitch window to reject switching noise. |
| UVLO Threshold | 4.5V rising, 4.2V falling - prevents erratic operation during brown-out; ensures clean startup above minimum motor drive voltage. |
| nFAULT Output | Open-drain, logic-low active - signals OCP/OVP/OTP faults; requires external pull-up for microcontroller interrupt detection. |
| Thermal Shutdown | 165°C junction, 15°C hysteresis - disables all outputs until die cools; enables automatic recovery without system reset. |
Pinout & Package
MP6604CGV-Z is housed in a thermally enhanced QFN-28 (4mm × 5mm) package with exposed thermal pad. Pin numbering follows JEDEC MO-220 VGHD-3 standard; Pin 1 is marked by corner chamfer or dot. The package supports reflow soldering per MSL Level 2 moisture sensitivity.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 1, 8) | Input supply rail | Dual input pins require independent 100nF ceramic bypass capacitors; bulk capacitance needed for high-current transients. |
| AOUT1 / AOUT2 / BOUT1 / BOUT2 (Pins 2, 4, 5, 7) | H-bridge output terminals | Drive motor windings or solenoids; each pair forms one full bridge; rated for 48V abs max and 2.5A continuous. |
| PGNDA / PGNDB (Pins 3, 6) | Power ground returns | Separate high-current ground paths per bridge minimize crosstalk and improve current sensing accuracy. |
| AHS1 / ALS1 / AHS2 / ALS2 / BHS1 / BLS1 / BHS2 / BLS2 (Pins 16–23) | Independent HS/LS gate control inputs | Direct CMOS-level logic control (VIH = 2V, VIL = 0.8V); internal 100kΩ pull-downs ensure safe Hi-Z default state. |
| nSLEEP / nRESET / nFAULT (Pins 14, 13, 15) | System control and status | nSLEEP disables charge pump and outputs (ISLEEP = 0.9–10µA); nRESET clears latched faults; nFAULT is open-drain fault flag. |
| VREG / VCP / CPA / CPB (Pins 12, 27, 25, 26) | Internal supply generation | VREG powers LS drivers (5V); VCP powers HS drivers (VIN+5V); CPA/CPB connect 100nF flying capacitor for charge pump operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent H-bridge topology | Enables simultaneous bidirectional control of two motors or precise bipolar stepper phase sequencing without external logic. |
| Automatic synchronous rectification | Reduces body-diode conduction loss during current recirculation; activates when xOUTx falls below GND or exceeds VIN. |
| Integrated charge pump & LDO | Eliminates need for external high-side gate driver ICs or bootstrap diodes; supports 100% duty-cycle operation. |
| Comprehensive fault protection | OCP, OVP, UVP, OTP, and fault reporting via nFAULT enable robust field-deployed motor control without external monitoring circuitry. |
| QFN-28 thermal design | Exposed thermal pad with recommended vias and copper pour achieves θJA = 40°C/W - critical for sustained 2.5A operation in compact enclosures. |

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 |
|---|---|---|---|
| TB6612FNG | Lower 1.2A max current; 2.5V–13.5V VIN range; no integrated charge pump - requires external bootstrap components. | Restricted to low-voltage, low-power robotics; unsuitable for 24V+ industrial loads or sustained 2.5A operation. | Select only for cost-sensitive, low-current (<1.2A), low-VIN (<13.5V) applications where board space allows discrete bootstrap design. |
| DRV8825 | Microstepping support; 2.2A RMS current; 8.2V–45V VIN; requires external current-sense resistors and charge pump capacitors. | Better suited for precision microstepping but lacks integrated OVP and has higher BOM count due to external components. | Choose when sub-step resolution is required and system can accommodate additional passive components and tuning effort. |
Compared with TB6612FNG and DRV8825, MP6604CGV-Z delivers higher current (2.5A), wider input range (4.5V–45V), fully integrated charge pump, and comprehensive fault protection - making it optimal for ruggedized 24V/36V motion control where reliability and minimal external components are prioritized.

FAQ
What is the maximum continuous output current per channel for MP6604CGV-Z?
The MP6604CGV-Z supports up to 2.5A continuous current per phase under specified thermal conditions (TA = 25°C, adequate PCB copper, and airflow). Actual current capability decreases with rising ambient temperature and reduced heatsinking - refer to the derating curve in Figure 7 of the datasheet for precise limits at elevated temperatures.
Does MP6604CGV-Z require external bootstrap capacitors?
No. MP6604CGV-Z integrates a charge pump circuit with dedicated CPA and CPB pins for a flying capacitor (100nF, VIN-rated), eliminating external bootstrap diodes and capacitors. This enables true 100% duty-cycle operation and simplifies PCB layout compared to bootstrap-based drivers.
How does the nFAULT pin behave during over-temperature events?
During over-temperature events, the internal thermal shutdown circuit disables all H-bridge outputs and pulls nFAULT low. Once the junction temperature drops below the hysteresis threshold (150°C), the device automatically resumes normal operation without requiring nRESET assertion - enabling self-recovering thermal protection.
Can MP6604CGV-Z drive unipolar stepper motors?
No. MP6604CGV-Z is designed exclusively for bipolar stepper motors and brushed DC motors. Its dual full-H-bridge architecture requires center-tapped or dual-winding configurations and cannot interface with unipolar stepper wiring that relies on single-ended transistor switching per phase.
What is the purpose of separate PGNDA and PGNDB pins?
PGNDA and PGNDB provide isolated high-current ground return paths for Bridge A and Bridge B, respectively. This separation minimizes ground bounce coupling between bridges, improves current-sensing accuracy, and enhances EMI performance - especially critical in multi-motor systems sharing a common control MCU.
Is MP6604CGV-Z RoHS-compliant and halogen-free?
Yes. MP6604CGV-Z is lead-free, halogen-free, and fully compliant with the EU RoHS directive. MPS confirms green status for this part on its official Quality Assurance webpage, and the device meets JESD204B and IPC/JEDEC J-STD-020 moisture sensitivity standards (MSL Level 2).
