Product details
Overview
MP2760GVT-040A-Z from Monolithic Power Systems is an I²C-controlled buck-boost battery charger IC for 4-cell Li-ion/Li-polymer packs (up to 18.72V), supporting 4V–22V input, up to 6A charge current, NVDC power path management, and USB PD 3.0 compliance. It enables dual-role operation-charging batteries from adapters while supplying regulated 4V–21V system power in source mode-used in high-density portable computing with thermal regulation and JEITA-compliant temperature protection.
For engineers reviewing the MP2760GVT-040A-Z datasheet, MP2760GVT-040A-Z pinout, MP2760GVT-040A-Z application, or MP2760GVT-040A-Z equivalent, key selection criteria include 4-cell battery voltage regulation accuracy (±0.5% at 25°C), configurable IN input current limit (0–5.8A), NVDC minimum system voltage setting (11.64–12.36V for 4 cells), and I²C-configurable source-mode output voltage (4.85–20.3V in 20mV steps).
Technical Context
The MP2760 implements a synchronous 4-switch buck-boost topology with integrated gate drivers for external N-channel MOSFETs (Q1–Q4), enabling seamless transition between buck and boost modes without discontinuity. Its dual-path architecture separates input current sensing (IAP/IAN) and battery current monitoring (TS/IMON), supporting independent regulation of charge current (up to 6A), input current limit, and source-mode output current (up to 6A).
Control is fully register-based via I²C/SMBus: all critical parameters-including battery full voltage (13.6–18.72V), pre-charge threshold (2.45–3.1V/cell), thermal regulation threshold (configurable up to 120°C), and JEITA temperature zones-are programmable. Safety logic includes hardware-enforced OVP/UVP on ADP, IN, SYS, and BATT rails, plus battery missing detection and NTC floating detection.

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 |
|---|---|---|---|
| BQ25792RTWR (TI) | Supports 1–4 cells but lacks integrated ACGATE driver; requires external MOSFET for input OVP; no analog IMON output pin. | Less suitable for space-constrained designs needing monolithic input OVP and current monitoring. | Prefer MP2760GVT-040A-Z when board area is limited and analog battery current telemetry is required. |
| LTC4162EUFD-4#PBF (Analog Devices) | Higher integration (integrated MOSFETs), but fixed 4-cell configuration only; no source-mode output capability; lower max charge current (3.2A). | Not viable for USB PD source applications or systems requiring >3.2A charge current. | Choose MP2760GVT-040A-Z for dual-role (charge + source) functionality and 6A capability in compact TQFN-30. |
Compared with BQ25792RTWR and LTC4162EUFD-4#PBF, MP2760GVT-040A-Z uniquely combines 6A bi-directional current handling, monolithic ACGATE/BGATE drivers, analog IMON output, and USB PD 3.0 source-mode compliance in a single 4mm×5mm package-enabling smaller, safer, and more flexible portable power architectures.

FAQ
What does the "-040A" suffix indicate in MP2760GVT-040A-Z?
The "-040A" suffix denotes the factory-default configuration for 4-cell battery applications, including OTP-programmed register settings for 4-cell battery voltage regulation (13.6–18.72V), minimum system voltage (11.64–12.36V), and JEITA temperature thresholds optimized for quad-cell stacks. This eliminates manual register initialization for basic 4S use cases.
Does MP2760GVT-040A-Z support true USB PD 3.0 sink and source roles simultaneously?
No-it supports sink (charge) and source (IN output) modes, but not concurrently. When in charge mode, the IN pin accepts power; when in source mode, the IN pin delivers regulated power (4–21V, up to 6A). Mode switching is controlled via I²C register REG00h[0], and hardware interlocks prevent conflicting states.
How is battery temperature monitored without an external ADC?
The MP2760 integrates a 10-bit ADC that digitizes voltage from the NTC thermistor divider connected to NTC/VNTC pins. Thresholds for cold/cool/warm/hot zones are stored in registers (REG0Dh), and the IC autonomously adjusts charge current or halts charging if thresholds are breached-no host processor intervention required.
Can the TS/IMON pin be used for both temperature sensing and current monitoring in the same design?
No-TS/IMON is a single-pin, dual-function terminal configured at startup via I²C register REG00h[1]. If set to temperature mode, it reads NTC voltage; if set to current mode, it outputs an analog voltage proportional to battery charge/discharge current (±6A full-scale). Hardware multiplexing prevents simultaneous use.
What is the purpose of the ACGATE pin, and why is a 1MΩ resistor required?
ACGATE drives the gate of an external N-channel MOSFET used for input over-voltage protection and adapter pass-through. The 1MΩ resistor between ACGATE and the MOSFET source limits gate current during fast transients, preventing shoot-through and ensuring clean turn-on/turn-off timing under fault conditions like ADP OVP events.
Is the MP2760GVT-040A-Z compatible with existing MP2760 evaluation kits?
Yes-EVKT-MP2760 evaluation kit supports all MP2760 variants, including MP2760GVT-040A-Z. The kit's GUI and firmware automatically detect the -040A OTP configuration and pre-load appropriate register maps, enabling immediate validation of 4-cell charging profiles, source-mode output, and JEITA thermal response.
How does the NVDC power path manage system voltage when the battery is deeply discharged?
When battery voltage falls below VSYS_MIN + VTRACK (e.g., 11.64V + 430mV = ~12.07V for 4 cells), the BATFET is actively modulated to supplement system load from the battery while maintaining SYS ≥ VSYS_MIN. This avoids system brownout without requiring battery recharging first-critical for "instant-on" portable devices.
