Product details
Overview
MP2650GV-0200-P from Monolithic Power Systems is an I²C-controlled, dual-mode (buck/boost) battery charger IC for 2-cell Li-ion/Li-polymer packs, integrating NVDC power path management, USB OTG support, and full thermal regulation. It delivers up to 5A charge current, accepts 4V–21V input, supports IMVP8-compliant system power monitoring via PSYS/IBM/IAM analog outputs, and operates in a QFN-30 (4mm×5mm) package.
For engineers reviewing the MP2650GV-0200-P datasheet, MP2650GV-0200-P pinout, MP2650GV-0200-P application, or MP2650GV-0200-P equivalent, key selection considerations include its configurable 2-cell-specific register defaults, integrated MOSFETs enabling compact layout, NVDC-enabled system runtime during battery depletion, and I²C-accessible safety timers and fault registers for embedded power management firmware integration.
Technical Context
The MP2650 operates in two distinct DC-DC topologies: buck mode when VIN > battery voltage (e.g., 15V adapter charging 8.4V 2S pack), and boost mode when VIN < battery voltage (e.g., 5V USB charging same pack). Its dual-phase architecture uses internal N-channel MOSFETs (Q1–Q5) with RDS(on) values of 6–16 mΩ to achieve high efficiency across both modes.
NVDC regulation maintains SYS voltage at a narrow range (e.g., 6.16V ±5mV for 2S) independent of battery state, enabling uninterrupted system operation even with a fully depleted or absent battery. The IC implements JEITA-compliant NTC-based temperature protection with four programmable thresholds (cold/cool/warm/hot) and provides PROCHOT assertion for CPU throttling during input overcurrent, battery overcurrent, or system undervoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Topology | Buck or boost switching converter - enables single-chip charging from both high-VIN (15V adapter) and low-VIN (5V USB) sources without external topology selection. |
| Max Charge Current | 5A - supports fast charging of 2S battery packs up to ~42W (8.4V × 5A) with integrated FETs and thermal regulation at 120°C. |
| Input Voltage Range | 4V to 21V - covers USB PD, standard 5V adapters, and 12–19.5V laptop-style inputs; withstands 28V transients for robustness. |
| Cell Configuration | 2-cell only (pre-configured by -0200 suffix) - factory-set register defaults target 8.4V regulation, pre-charge threshold at 6.2V, and 2S-specific JEITA windows. |
| Switching Frequency | 600kHz / 800kHz / 1MHz / 1.25MHz - selectable via I²C to optimize efficiency vs. size trade-off using 1.5μH inductors. |
| Power Path Control | Narrow-voltage DC (NVDC) - regulates SYS bus to fixed 6.16V (2S default) with ±5mV tracking, allowing system load to run directly from adapter while charging battery. |
| USB OTG Support | Up to 5V/3A output - bidirectional boost converter powered from battery, with short-circuit protection and I²C-configurable current limit (1.43A or 2.93A typical). |
| Monitoring Outputs | PSYS (system power), IAM (input current), IBM (battery current) - analog current-source/sink outputs compliant with IMVP8 for real-time host-side power budgeting. |

Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-path power FETs | Five internal N-channel MOSFETs (Q1–Q5) with RDS(on) 6–16 mΩ eliminate 10+ external components and reduce solution footprint by >40% vs. discrete designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost battery charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25720RSNR | Single-input (no dual IN/OTG path), no integrated OTG FET; requires external boost converter for OTG; supports 1–4S but lacks 2S factory config. | Requires additional components for OTG functionality; less suitable for space-constrained 2S devices needing integrated OTG. | Select if OTG is not required and higher integration density is not critical; verify external boost design for 5V/3A compliance. |
| ISL9241IRZ-T | Supports 1–4S but uses different JEITA implementation (two-point vs. four-point NTC); no PSYS/IBM/IAM analog outputs; relies on SMBus instead of I²C. | Lacks IMVP8 analog monitoring needed for Intel platform power telemetry; JEITA windows less granular than MP2650's cold/cool/warm/hot. | Prefer for non-Intel platforms where SMBus is already used; avoid when PSYS-based dynamic power capping is required. |
Compared with BQ25720RSNR and ISL9241IRZ-T, MP2650GV-0200-P uniquely combines 2S-optimized factory defaults, integrated OTG FET, and IMVP8-compliant analog telemetry in one QFN-30 package - reducing component count and firmware complexity for compact, battery-backed consumer devices.

FAQ
What does the "-0200" suffix indicate in MP2650GV-0200-P?
The "-0200" suffix denotes a factory-programmed configuration optimized for 2-cell Li-ion/Li-polymer battery packs. It sets default register values including 8.4V battery regulation voltage, 6.16V minimum system voltage, and JEITA temperature thresholds calibrated for 2S operation - eliminating the need for initial I²C programming during startup.
How does NVDC power path management improve system reliability?
NVDC maintains a tightly regulated SYS rail (e.g., 6.16V ±5mV) independent of battery voltage or presence. This allows the system load to operate continuously from the input source even when the battery is fully depleted, removed, or deeply discharged - preventing unexpected shutdowns and enabling hot-swap battery replacement in field-deployed devices.
Can MP2650GV-0200-P support USB Power Delivery (PD) input?
Yes - the IC accepts input voltages up to 21V with 28V transient tolerance, making it compatible with USB PD 3.0 profiles (e.g., 9V/3A, 15V/3A). Its wide VIN range and I²C-configurable VIN limit allow safe operation with variable PD voltages while maintaining optimal charging efficiency in buck or boost mode.
What safety protections are implemented in hardware versus firmware?
Hardware protections include input OVP (24V threshold), battery OVP (320mV above regulation), thermal shutdown (150°C), and short-circuit detection in OTG mode. Firmware-accessible protections - such as JEITA temperature windows, charge timers, and PROCHOT assertion conditions - are configured via I²C registers and enforced by on-chip logic without host intervention.
Is an external current-sense resistor required for input current monitoring?
Yes - a precision shunt resistor (e.g., 10mΩ) must be placed between IN and IAP/IAN pins to enable accurate input current measurement. The IAM pin outputs a voltage (250mV/A + 100mV offset) proportional to current through this resistor, allowing host MCU ADC reading without external amplification.
How is USB OTG functionality enabled and controlled?
OTG mode is activated by setting the OTG_EN bit in register REG07h and driving the OTG pin high (or configuring it as CMIN via I²C). Output voltage (5.0V default) and current limit (1.43A or 2.93A typical) are set via REG06h and REG07h. Short-circuit protection triggers automatic shutdown within 25.6ms upon fault detection.
Does MP2650GV-0200-P support battery fuel gauge integration?
While not a dedicated fuel gauge IC, MP2650GV-0200-P provides high-accuracy battery current sensing via the IBM pin (125mV/A charge, 62.5mV/A discharge) and voltage monitoring through system-level ADCs. Combined with host firmware implementing Coulomb counting and voltage-based SOC algorithms, it enables robust fuel gauging without additional ICs.
