Product details
Overview
MP2650GV-0300-Z from Monolithic Power Systems is an I²C-controlled buck/boost battery charger IC optimized for 3-cell Li-ion/Li-polymer battery packs (12.6V nominal), featuring integrated NVDC power path management, USB OTG support up to 5V/3A, and full thermal regulation at 120°C. It delivers up to 5A charge current, supports 4V–21V input, and enables system operation even with depleted or absent battery via regulated SYS rail.
For engineers reviewing the MP2650GV-0300-Z datasheet, MP2650GV-0300-Z pinout, MP2650GV-0300-Z application, or MP2650GV-0300-Z equivalent, key selection considerations include its 3-cell-specific register configuration (-0300), QFN-30 package layout, NVDC behavior under low-battery conditions, and I²C-configurable safety timers and current limits.
Technical Context
The MP2650 operates in dual-mode DC/DC topology: buck mode when VIN > battery voltage (e.g., 15V adapter charging 12.6V pack), and boost mode when VIN < battery voltage (e.g., 5V USB charging same pack). Its integrated Q1–Q5 MOSFETs enable seamless transition between charging, system power delivery, and OTG discharge without external switches.
NVDC regulation maintains SYS voltage within ±50mV of setpoint (e.g., 6.16V for 2-cell, 9.24V for 3-cell) independent of battery state, while PSYS, IAM, and IBM analog outputs provide real-time system power (100µA/W), input current (250mV/A), and bidirectional battery current (±125mV/A charging, ±62.5mV/A discharging) monitoring per IMVP8 compliance.
Key Specifications

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 (TI) | Supports 1–4 cells; no integrated OTG FET; requires external NMOS for discharge path; 12-bit ADC vs. MP2650's 10-bit | Targeted at industrial battery packs where OTG is unused; lacks PSYS analog output for IMVP8 | Select if needing higher-resolution telemetry or multi-cell flexibility beyond fixed 3S configuration |

FAQ
What does the "-0300" suffix indicate in MP2650GV-0300-Z?
The "-0300" denotes factory-programmed register defaults optimized for 3-cell battery packs: VBATT_REG = 12.59V, pre-charge threshold = 6.2V, and NVDC system voltage = 9.24V. This eliminates post-silicon configuration for standard 3S applications, reducing firmware development time and validation effort.
How does NVDC power path management function during battery removal?
When the battery is removed or fully depleted, MP2650GV-0300-Z sustains SYS rail voltage using input power only, regulating it to the configured value (e.g., 9.24V for 3S) with ±50mV accuracy. The integrated Q5 FET blocks reverse current, preventing SYS from back-driving the battery terminals.
Can MP2650GV-0300-Z operate in boost mode with a 5V USB input charging a 3S battery?
Yes - with VIN = 5V and a 12.6V 3S battery, MP2650GV-0300-Z automatically enters boost charging mode, using SW2/BST2/CP1/CP2 to generate boosted gate drive and deliver up to 5A charge current. Efficiency exceeds 85% at 3A/12.6V per typical curves.
What protections are active during USB OTG operation?
During OTG mode, MP2650GV-0300-Z provides short-circuit protection (25.6ms recovery), over-voltage protection (125% of setpoint), under-voltage protection (75% of setpoint), and thermal shutdown. The OTG output current limit is configurable from 1.075A to 3.27A via I²C register REG07h[3:0].
Is the PROCHOT pin compatible with Intel mobile processors?
Yes - PROCHOT is an open-drain output compliant with Intel PROCHOT# specification: it asserts low at 5.84V SYS undervoltage or 12A battery discharge, with 160mV hysteresis. External 4.7kΩ pull-up to VCC (3.6V) meets voltage and timing requirements for direct EC/CPU interfacing.
How is battery temperature monitored using NTC inputs?
NTC thermistor connects between NTC pin and AGND, with VNTC providing bias. MP2650GV-0300-Z compares NTC voltage against four JEITA thresholds (cold/cool/warm/hot) derived as % of VNTC. Thresholds are configurable via REG0Ah/REG0Ch, with hysteresis of 0.9–1.4% to prevent chatter.
Does MP2650GV-0300-Z support charging from multiple input sources simultaneously?
No - it supports single-input operation (IN pin only). Dual-input systems require external OR-ing FETs or diodes upstream of IN. The IC monitors ACOK to detect input presence but does not manage source arbitration or priority switching internally.
