Monolithic Power Systems Inc. MP2760GVT-030A-Z

Overview

MP2760GVT-030A-Z from Monolithic Power Systems is a fully integrated I²C-controlled buck-boost battery charger optimized for 3-cell Li-ion/Li-polymer packs (up to 14.04V), supporting 4V–22V input, up to 6A charge current, NVDC power path management, and USB PD 3.0 compliance. It enables simultaneous system power and battery charging in ultrabooks and portable USB-C devices.

For engineers reviewing the MP2760GVT-030A-Z datasheet, MP2760GVT-030A-Z pinout, MP2760GVT-030A-Z application, or MP2760GVT-030A-Z equivalent, key selection criteria include configurable 3-cell battery regulation (10.2–14.04V), 500kHz–1.2MHz switching frequency, thermal regulation at 120°C, I²C-accessible safety thresholds, and TQFN-30 package layout constraints.

Technical Context

The MP2760 implements a synchronous 4-switch buck-boost topology with integrated N-channel MOSFET drivers (ACGATE, BGATE) and dual bootstrap circuits (BST1/BST2) enabling seamless transition between buck and boost modes across varying VIN–VBATT differentials. Its NVDC architecture uses an external BATFET controlled by BGATE to maintain regulated SYS voltage independent of battery state.

Charge sequencing is fully programmable via I²C: trickle/pre/fast/constant-voltage phases are triggered by precise voltage thresholds (e.g., pre-charge threshold = 2.9–3.1V/cell), with termination based on configurable ITERM (100–400mA) and timer limits (1.8–22hr). Source mode provides 4V–21V IN output (VIN_SRC) with up to 6A IIN_SRC, compliant with USB PD 3.0 voltage/current profiles.

FAQ

What does the "-030A" suffix indicate in MP2760GVT-030A-Z?

The "-030A" denotes the factory-programmed OTP configuration for 3-cell battery operation, including default settings for 10.2–14.04V battery regulation voltage, 3-cell pre-charge threshold (2.9–3.1V/cell), and corresponding JEITA temperature zone thresholds. This eliminates manual register initialization for standard 3S applications.

How does NVDC power path management improve system reliability?

NVDC decouples SYS voltage from battery voltage using the BGATE-driven external BATFET. This ensures the system remains powered even when the battery is deeply discharged or removed, and allows immediate system startup without waiting for battery recharge - critical for always-on portable devices.

Can MP2760GVT-030A-Z support USB PD Programmable Power Supply (PPS)?

Yes - its I²C-configurable VIN_SRC (4V–21V in 20mV steps) and IIN_SRC (up to 6A in 50mA steps), combined with real-time voltage/current monitoring via TS/IMON and ADC, meet USB PD 3.0 PPS requirements for dynamic output adjustment during communication with a PD controller.

What thermal design considerations apply to the TQFN-30 package?

The TQFN-30 requires ≥8 thermal vias (0.3mm diameter) under the exposed pad, connected to a solid PGND plane on inner layers. With θJA = 38°C/W, continuous 6A operation demands ≤25°C ambient or active airflow to maintain TJ < 120°C under thermal regulation.

Is external current-sense resistor required for charge current measurement?

Yes - the MP2760 uses differential sensing across an external resistor connected to SRP/SRN pins. Typical value is 5mΩ for 6A full-scale measurement, yielding 30mV drop; the IC's ±3.6V common-mode range supports high-side placement for ground-referenced system designs.

How is battery temperature protection implemented without external components?

Using the integrated NTC comparator, VNTC bias, and TS/IMON pin configured as temperature input. The IC compares NTC voltage against four factory-configurable thresholds (cold/cool/warm/hot) stored in registers, triggering charge suspend or reduce actions - no external op-amps or ADCs needed.

Does MP2760GVT-030A-Z support automatic recharge after battery self-discharge?

Yes - when battery voltage drops below the auto-recharge threshold (configurable down to 120mV/cell below full regulation voltage), the IC restarts the full charge cycle. This threshold and associated deglitch time (240ms) are set via I²C register REG10h bit[11] and REG12h.
