Product details
Overview
MP2650GV-0400-Z from Monolithic Power Systems is a fully integrated I²C-configurable buck/boost battery charger IC designed for 4-cell Li-ion/Li-polymer battery packs (up to 16.8V nominal). It delivers up to 5A charge current and 5A input current, supports NVDC power path management, USB OTG (5V/3A), and integrates all power MOSFETs in a QFN-30 (4mm×5mm) package. Used in high-density portable systems where seamless system operation during battery depletion is required.
For engineers reviewing the MP2650GV-0400-Z datasheet, MP2650GV-0400-Z pinout, MP2650GV-0400-Z application, or MP2650GV-0400-Z equivalent, key selection considerations include 4-cell configuration default, NVDC regulation tolerance (±5mV tracking), thermal regulation setpoint (120°C), configurable switching frequency (600–1250kHz), and IMVP8-compliant PSYS/IAM/IBM analog monitoring outputs.
Technical Context
The MP2650 operates in dual-mode topology: buck charging when VIN > battery voltage, boost charging when VIN < battery voltage - automatically selected based on input voltage and cell count. Its NVDC architecture maintains system bus voltage (VSYS) within ±5mV of regulated target even during battery removal or deep discharge.
It implements full I²C register control over charging parameters (VBATT_REG = 16.8V for 4-cell, ICC up to 5A, IIN_LIM up to 5A), safety timers, JEITA-compliant NTC temperature profiling, and OTG output (VIN_OTG = 5.0V ±2%, IOLIM = 3.27A max), with real-time status reporting via INT and PROCHOT pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Topology | Buck or boost mode, auto-selected per VIN vs. battery voltage - enables single-chip charging across wide adapter ranges (4–21V). |
| Max Charge Current | 5A - supports fast charging of 4-cell packs (e.g., 16.8V/20Wh) at ≤1.5C rate with integrated FETs. |
| NVDC Regulation Accuracy | ±5mV tracking error - ensures stable system rail (VSYS) during battery transition, critical for uninterrupted CPU operation. |
| Switching Frequency | Configurable 600/800/1000/1250kHz - allows optimization of inductor size vs. efficiency (e.g., 1MHz for <1.5μH inductors). |
| USB OTG Output | 5.0V ±2% @ up to 3.27A - provides compliant host power without external LDO or DC-DC stage. |
| Thermal Regulation Setpoint | 120°C - actively throttles charge current before thermal shutdown (150°C), preserving battery health and runtime. |
| I²C Register Access | Full read/write access to 24+ configuration/status registers - enables dynamic adaptation (e.g., JEITA profile switching, PROCHOT assertion thresholds). |
Pinout & Package
MP2650GV-0400-Z is housed in a thermally enhanced QFN-30 (4mm × 5mm, 0.5mm pitch) package with exposed thermal pad. Pin numbering follows standard top-view layout (Pin 1 at top-left corner, counter-clockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 22 IN | Power input | Accepts 4–21V adapter/USB input; withstands 28V transient (20ns) - eliminates need for external OVP clamp. |
| 5 OTG | OTG enable / comparator input | Configurable I²C pin: asserts OTG mode or serves as independent comparator input (CMIN) for custom fault detection. |
| 6, 17 SYS | System power rail | Regulated output (6.16V min for 4-cell) - powers SoC, display, and peripherals directly via NVDC path. |
| 7, 16 BATT | Battery positive terminal | Connects to 4-cell stack (max 18V); integrates ideal diode FET (RON_Q5 = 11mΩ) for low-loss discharge path. |
| 8 PROCHOT | Processor hot interrupt | Open-drain signal pulled low at 5.84V VSYS UV or 12A battery discharge OC - triggers CPU throttling per IMVP8 spec. |
| 12 PSYS | System power monitor | Current-source output (100µA full-scale = 256 steps) proportional to total system power - enables real-time power budgeting. |
| 13 IBM | Battery current sense | Voltage output: 125mV/A (charge), 62.5mV/A (discharge) - supports bidirectional current monitoring without shunt reversal. |
| 14 IAM | Input current sense | 250mV/A gain + 100mV offset - enables accurate adapter current limiting and source prioritization. |
| 15 BST2, 23 BST1 | Bootstrap supplies | Drive high-side FET gates above SWx nodes using 470nF caps - sustains 100% duty cycle in boost/buck phases. |
| 26 VCC | Internal LDO output | 3.6V/50mA supply for logic and pull-ups (ACOK, INT, PROCHOT) - reduces external bias requirements. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated buck/boost power stage | All five MOSFETs (Q1–Q5) embedded - eliminates 10+ discrete components and saves ≥25mm² PCB area. |
| NVDC power path with battery FET | Integrated SYS-to-BATT FET (RON_Q5 = 11mΩ) enables zero-volt battery boot and seamless AC/battery switchover. |
| IMVP8-compliant analog monitors | Dedicated PSYS, IAM, IBM pins with calibrated gain/offset - replaces external ADC and current-sense amplifiers. |
| JEITA-compliant NTC interface | Four programmable temperature thresholds (cold/cool/warm/hot) with hysteresis - meets battery safety standards without MCU intervention. |
| Configurable safety timer | Programmable 1–12 hour total charge timer (REG09h) - prevents overcharge of degraded or mismatched cells. |
| USB OTG with SCP | 5V/3.27A output with short-circuit protection - delivers certified host power without secondary regulator or fuse. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck/boost charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25792RTWR | Single-input (no dual-path IN/SYS), lower max IIN (3.5A), no integrated OTG FET - requires external boost converter for OTG. | Targeted at cost-sensitive notebooks; lacks native 5V/3A OTG output and PSYS analog monitor. | Select if OTG is unused and IMVP8 telemetry is not required - saves ~$0.30 but adds 2–3 external components. |
| ISL9241IRZ-T | Fixed 4-cell config only, no boost mode, higher quiescent current (25μA vs. 60μA in battery-only mode), no PROCHOT output. | Optimized for low-power tablets; missing thermal regulation, OTG, and processor-interrupt features. | Choose only for simple 4-cell buck charging where NVDC, OTG, and IMVP8 compliance are unnecessary. |
Compared with BQ25792RTWR and ISL9241IRZ-T, MP2650GV-0400-Z uniquely integrates buck/boost topology, 5V/3A OTG, IMVP8 analog monitors, and thermal regulation in one QFN-30 package - reducing solution size by ≥30% and enabling feature-rich portable designs without compromise.

FAQ
What does the "-0400" suffix indicate in MP2650GV-0400-Z?
The "-0400" denotes factory-programmed register defaults optimized for 4-cell battery applications: VBATT_REG = 16.8V (4 × 4.2V), pre-charge threshold = 6.6V, and JEITA cold/warm thresholds configured for Li-ion. This eliminates manual I²C initialization for standard 4S packs.
How does NVDC power path management behave when the battery is removed?
With battery disconnected, MP2650GV-0400-Z regulates VSYS directly from the input (IN) using buck or boost mode as needed, maintaining system operation at the programmed VSYS voltage (e.g., 6.16V for 4-cell). The SYS rail remains active without interruption or brownout.
Can MP2650GV-0400-Z support USB-C Power Delivery input?
Yes - its 4–21V input range and 28V transient rating (20ns) accommodate USB-C PD 3.0 variable voltages (5V/9V/15V/20V). Input current limit (IIN_LIM) and VIN clamp (VIN_MIN) are I²C-configurable to match PD contract negotiation results.
What is the function of the PSYS pin, and how is it calibrated?
PSYS outputs a current source proportional to total system power (VSYS × ISYS). Full-scale (256 steps) corresponds to 100µA, calibrated to ±5% accuracy. External resistor (e.g., 14.7kΩ) converts it to voltage (0–1.47V) for MCU ADC reading - enabling real-time power budgeting.
Does MP2650GV-0400-Z require external current-sense resistors?
No - it uses integrated high-side sensing for IAM (input) and IBM (battery) with factory-trimmed gain (250mV/A and 125mV/A respectively). Only RS1 (10mΩ) is required for input current sensing, placed between IN and IAP/IAN pins per datasheet layout guidelines.
How is thermal regulation implemented, and what happens at 120°C?
Die temperature is monitored internally. At 120°C, the IC dynamically reduces charge current (ICC) and input current (IIN_LIM) to maintain equilibrium - preventing thermal shutdown (150°C) while sustaining safe operation and battery longevity.
Is the MP2650GV-0400-Z RoHS and REACH compliant?
Yes - MP2650GV-0400-Z is lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. MPS green status documentation is available at monolithicpower.com/quality-assurance.
