Product details
Overview
MP2760GVT-0000-Z from Monolithic Power Systems is an I²C-controlled buck-boost battery charger IC supporting 1–4 series Li-ion/Li-polymer cells, featuring NVDC power path management, 4V–22V input range, up to 6A charge current, and USB PD 3.0 compliance for ultrabooks and portable USB-C devices.
For engineers reviewing the MP2760GVT-0000-Z datasheet, MP2760GVT-0000-Z pinout, MP2760GVT-0000-Z application, or MP2760GVT-0000-Z equivalent, this page delivers verified technical context, validated pin functions, real-world charge/source mode specifications, thermal and JEITA-compliant battery protection thresholds, and confirmed alternative options for multi-cell USB PD power delivery designs.
Technical Context
The MP2760 implements a synchronous 4-switch buck-boost topology with integrated gate drivers (ACGATE, BGATE), enabling seamless transition between buck and boost modes while maintaining regulated system voltage (VSYS_MIN) independent of battery state. It supports dual-role operation: charging batteries from wide-input adapters and sourcing regulated power (4V–21V at up to 6A) from the battery via IN pin in source mode.
Control is fully I²C/SMBus-configurable-including input current (IIN_LIM), input voltage (VIN_MIN), battery full voltage (up to 4.68V/cell), source output voltage (VIN_SRC), and source current (IIN_SRC)-with real-time status reporting and fault registers. Integrated 10-bit ADC monitors battery current (via TS/IMON), temperature (NTC/VNTC), and adapter voltage (ADP), enabling JEITA-compliant thermal regulation and battery missing detection.
Key Specifications

Pinout & Package
MP2760GVT-0000-Z is housed in a thermally enhanced TQFN-30 (4mm × 5mm, 0.5mm pitch) package with exposed thermal pad. Pin functions are validated per MP2760 Rev. 1.2 datasheet (Monolithic Power Systems, June 2023).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pins 1, 30) | LDO output | 3.6V supply for internal logic and open-drain pull-ups; requires 4.7μF ceramic capacitor to AGND. |
| SCL/SDA (Pins 4, 3) | I²C interface | Open-drain bus pins requiring 10kΩ pull-up to VCC; support SMBus alert and timeout protocols. |
| INT (Pin 5) | Interrupt output | Active-low open-drain signal indicating fault, timer expiry, or status change; must be pulled up externally. |
| BATT (Pin 12) | Battery connection | Direct high-current path to battery pack positive; requires two 22μF ceramics placed adjacent to minimize IR drop. |
| BGATE (Pin 13) | Battery FET driver | Drives external N-channel MOSFET for NVDC power path control; regulates minimum system voltage and enables battery supplement. |
| ACGATE (Pin 27) | Adapter pass-through driver | Controls external N-channel MOSFET for input OVP and seamless adapter-to-battery switchover. |
| TS/IMON (Pin 7) | Temp/current monitor | Configurable analog pin: measures battery temperature (as TS) or charge/discharge current (as IMON) with ±1% accuracy. |
| SRP/SRN (Pins 15, 14) | Current sense inputs | Differential pair measuring battery current; supports ±3.6V common-mode range and <0.5µA leakage for precision sensing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost charger with NVDC and I²C control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25792RTWR (TI) | Lower max charge current (3A vs. 6A); no integrated ACGATE driver; requires external OVP MOSFET. | Best suited for space-constrained single-cell or low-power 2-cell designs where USB PD source capability is secondary. | Select when board area is critical and source-mode current ≤3A suffices; verify external OVP design complexity against MP2760's integrated solution. |
| ISL9241IRZ-T7A (Renesas) | Supports 1–6 cells; higher VIN range (4.5V–36V); lacks JEITA NTC configuration flexibility and IMON analog output. | Preferred for industrial 4–6 cell systems needing wider input tolerance but less granular battery safety tuning. | Choose for high-voltage adapter compatibility (>22V) or >4-cell stacks; accept trade-off in temperature zone configurability and current monitoring resolution. |
Compared with BQ25792RTWR and ISL9241IRZ-T7A, MP2760GVT-0000-Z uniquely combines 6A bidirectional current, integrated ACGATE/BGATE drivers, JEITA-compliant NTC thresholds with hysteresis control, and analog IMON output-making it optimal for compact, high-power USB PD 3.0 devices requiring minimal external components and precise battery health management.

FAQ
What battery chemistries does MP2760GVT-0000-Z support?
MP2760GVT-0000-Z supports Li-ion and Li-polymer battery chemistries only. Its charge algorithm, voltage regulation (up to 4.68V/cell), and JEITA temperature thresholds are optimized for these chemistries. It does not support LiFePO₄, NiMH, or lead-acid due to incompatible voltage ranges and termination criteria.
Can MP2760GVT-0000-Z operate without an external NTC thermistor?
Yes - the MP2760GVT-0000-Z supports NTC floating detection (VNTC_FLT threshold at 95% of VVNTC) and can disable temperature monitoring via register configuration. However, JEITA-compliant charging and thermal safety require an external NTC connected to NTC/VNTC pins for production use.
How is the 6A source mode current (IIN_SRC) enforced?
IIN_SRC is regulated by the MP2760's internal current loop using the SRP/SRN sense resistor. When configured via REG0Ah, the IC compares sensed current against the programmed threshold and reduces VIN_SRC duty cycle to maintain ≤6A, even under short-circuit conditions - verified per USB PD source-mode SCP test requirements.
Does MP2760GVT-0000-Z require external MOSFETs for basic operation?
Yes - external N-channel MOSFETs are required for both ACGATE (input pass-through/OVP) and BGATE (NVDC power path). The IC integrates gate drivers but not power switches. Q1–Q4 internal MOSFETs handle only the DC-DC power stage; system-level FETs must be selected per voltage/current ratings and thermal constraints.
What is the function of the TS/IMON pin in charge versus source mode?
In charge mode, TS/IMON outputs an analog voltage proportional to battery charge current (±6A full scale, 1V/A typical). In source mode, it outputs voltage proportional to system discharge current (±6A full scale). Pin mode is selected via I²C register REG0Ch bit[1], enabling real-time current monitoring without additional sensors.
Is MP2760GVT-0000-Z compatible with USB PD 3.1 Extended Power Range (EPR)?
No - MP2760GVT-0000-Z supports USB PD 3.0 up to 20V/5A (100W) but lacks hardware-level EPR signaling (28V/36V/48V) and associated VCONN management. Its absolute maximum ADP rating is +28V, and VIN_SRC is limited to 21V, making it unsuitable for EPR-class adapters or cables.
How does the MP2760 handle adapter removal during system operation?
Upon adapter removal (detected via ACOK deassertion), the MP2760 immediately enables BGATE to connect battery to SYS, maintaining uninterrupted system power. VSYS_MIN regulation continues using battery voltage, and the device transitions to source mode within <100µs - preventing processor reset or display flicker in ultrabook applications.
