Product details
Overview
MP2651GVT-030A-Z from Monolithic Power Systems is a buck-boost battery charger IC configured for 3-cell Li-ion/Li-polymer battery packs (10.2–14.01V regulation range), supporting bidirectional operation with I²C/SMBus programmable charge current up to 6A, input voltage range 4V–22V, and source-mode output 4V–21V. It integrates four-phase charging control, thermal regulation, JEITA-compliant temperature monitoring, and USB PD 3.0–compatible source mode-used in portable power banks requiring multi-cell fast charging and reverse power delivery.
For engineers reviewing the MP2651GVT-030A-Z datasheet, MP2651GVT-030A-Z pinout, MP2651GVT-030A-Z application, or MP2651GVT-030A-Z equivalent, key selection criteria include 3-cell factory OTP configuration, TQFN-30 package thermal performance, I²C-configurable VIN_MIN and IIN_SRC limits, and integrated NTC biasing for battery temperature protection in high-reliability portable systems.
Technical Context
The MP2651GVT-030A-Z implements a synchronous 4-switch buck-boost topology with internal MOSFET drivers (RON_Q1 = 10mΩ, RON_Q2 = 8mΩ, RON_Q3 = 8mΩ, RON_Q4 = 20mΩ) enabling seamless transition between buck and boost modes across input-to-battery voltage inversion. Its dual-role architecture supports charge mode (CC/CV with trickle/pre-charge/termination) and reverse source mode (regulated VIN_SRC with 20mV/step resolution and 50mA/step IIN_SRC limit).
Control is fully I²C/SMBus-based (10–400kHz clock, 1.8V/3.3V logic compatible), with register-mapped parameters including battery-full voltage (±0.5% accuracy at 12.6V), input UVLO/OVLO thresholds (configurable per REG11h), and thermal regulation setpoint (120°C). Safety is enforced via independent analog comparators for battery OVP (230mV/cell), input OVP (24.7V), and die temperature shutdown (150°C).

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-inductor buck-boost with lower max charge current (3A) and no factory OTP variants; requires external NTC biasing | Targeted at space-constrained wearables rather than 3S power banks | Select when board area is critical and 3A charge current suffices |
| ISL9241IRZ-T7A | Higher integration (integrated ADC, Coulomb counter) but fixed 4.2V/cell regulation; no source-mode output | Optimized for notebook battery packs, not bi-directional portable devices | Select when precise fuel gauging is required and reverse power delivery is unnecessary |
Compared with BQ25792RTWR and ISL9241IRZ-T7A, the MP2651GVT-030A-Z uniquely combines factory-configured 3-cell operation, 6A bidirectional current capability, and USB PD–ready source mode in a single TQFN-30 package-enabling compact, high-power portable designs without firmware calibration overhead.

FAQ
What does the "-030A" suffix indicate in MP2651GVT-030A-Z?
The "-030A" suffix denotes factory-programmed OTP configuration for 3-cell battery applications, setting default battery regulation range to 10.2–14.01V and enabling immediate operation without I²C register initialization. This eliminates boot-time configuration delays and reduces firmware complexity in mass-produced portable devices.
How does the MP2651GVT-030A-Z handle thermal regulation during high-current charging?
The device uses an internal die temperature sensor with configurable 120°C regulation threshold (REG0Fh bits[14:12] = 111) and 20°C hysteresis. When exceeded, it dynamically reduces charge current to maintain safe junction temperature, verified by 150°C thermal shutdown as final protection-ensuring reliability in enclosed power bank enclosures.
Can the MP2651GVT-030A-Z operate without an external NTC thermistor?
Yes-it supports NTC floating detection (VNTC_FLT at 95% of VVNTC) and battery missing detection via SRP/SRN offset, allowing safe operation in simplified designs. However, JEITA temperature profiling (cold/cool/warm/hot zones) requires an external NTC connected to NTC/VNTC pins for full safety compliance.
What is the purpose of the ACGATE pin, and how is it used in OVP protection?
The ACGATE pin drives an external N-channel MOSFET for input power path control. During ADP over-voltage events (e.g., >24.7V), the IC disables ACGATE to disconnect the input source before power stage shutdown-providing fail-safe protection that prevents damage to downstream components during transient surges.
Does the MP2651GVT-030A-Z support simultaneous charge and source operation?
No-it operates exclusively in charge mode (IN→BATT) or source mode (BATT→IN), with automatic mode switching controlled by presence of input power and register settings. Simultaneous bidirectional power flow is not supported; the architecture prioritizes safety isolation between input and battery domains.
How is the 3-cell configuration validated across temperature and process variation?
The factory OTP setting for 3-cell operation is laser-trimmed and tested across −40°C to +125°C, ensuring ±0.5% battery voltage regulation accuracy at 12.6V over full temperature range. Electrical characterization data (page 8–9 of Rev. 1.2 datasheet) confirms stability of VBATT_REG and ICC_ACC under thermal stress.
What are the minimum external components required for basic operation?
Essential components include: four 10μF ceramic capacitors on IN–PGND, one 22μF capacitor on BATT–PGND, 100nF bootstrap capacitors on BST1–SW1 and BST2–SW2, 22μF filter caps on CFLR–PGND, 4.7μF on VCC–AGND, and 10kΩ pull-ups on SCL/SDA. The evaluation board EV2651-VT-00A demonstrates this minimal BOM.
