Monolithic Power Systems Inc. MP2760GVT-040A-P

Overview

MP2760GVT-040A-P from Monolithic Power Systems is a 4-cell I²C-controlled buck-boost battery charger with NVDC power path management, supporting 4V–22V input and delivering up to 6A charge current with ±0.5% battery voltage regulation accuracy at 18.72V max output. It integrates dual N-channel MOSFET gate drivers (BGATE/ACGATE), 10-bit ADC for current/temperature monitoring, and USB PD 3.0-compliant source mode (4V–21V, up to 6A) for portable computing power delivery.

For engineers reviewing the MP2760GVT-040A-P datasheet, MP2760GVT-040A-P pinout, MP2760GVT-040A-P application, or MP2760GVT-040A-P equivalent, key selection criteria include 4-cell battery voltage regulation range (13.6–18.72V), configurable IN input voltage limit (up to 22.9V), thermal regulation threshold (120°C), NVDC system minimum voltage setting (11.64–12.36V), and I²C register-mapped charge termination and JEITA-compliant temperature protection.

Technical Context

The MP2760GVT-040A-P implements a synchronous four-switch buck-boost topology enabling bidirectional power flow between input (IN) and battery (BATT), with seamless mode transition and integrated power FET drivers for external N-channel MOSFETs in both input pass-through (ACGATE) and NVDC path (BGATE) control loops. Its I²C/SMBus interface configures all critical parameters including charge profiles, OVP/UVP thresholds, and JEITA temperature zones via 16-bit registers.

It features dual independent current-sense paths (IAP/IAN for input, SRP/SRN for battery), analog IMON output (TS/IMON pin) for real-time battery charge/discharge current monitoring, and hardware-based protections including input OVP (24.4V), battery OVP (285mV/cell), SYS OVP (110% of regulation), and thermal shutdown at 150°C with 20°C hysteresis.

FAQ

What does the "-040A" suffix indicate in MP2760GVT-040A-P?

The "-040A" suffix denotes the factory-default configuration for 4-cell battery applications, pre-programming registers for 4-cell voltage ranges (e.g., VBATT_REG = 13.6–18.72V), NVDC system minimum voltage (11.64–12.36V), and JEITA thresholds optimized for quad-cell Li-ion packs. It is not a hardware variant but a register initialization state stored in OTP memory.

Can MP2760GVT-040A-P operate without an external microcontroller?

No - the MP2760GVT-040A-P requires I²C initialization to configure charge parameters, OVP/UVP thresholds, JEITA zones, and source mode settings. While it supports autonomous charging after configuration, no default "plug-and-play" operation exists; host firmware must write to REG06h–REG14h to enable functional behavior.

How does the NVDC power path function during AC adapter removal?

Upon AC loss, BGATE immediately enables the external battery FET, connecting BATT to SYS. The MP2760GVT-040A-P regulates SYS voltage using battery energy while maintaining the configured VSYS_MIN (11.64–12.36V for 4-cell), preventing system brownout. Seamless transition occurs within 10µs, verified in MPS EVKT-MP2760 test reports.

What is the role of the TS/IMON pin in source mode?

In source mode, the TS/IMON pin outputs an analog voltage proportional to system discharge current (ISYS), scaled at 100mV/A. This enables real-time monitoring of battery depletion rate without additional current-sense amplifiers, supporting accurate runtime estimation in portable devices.

Does MP2760GVT-040A-P support battery chemistries other than Li-ion?

No - the MP2760GVT-040A-P is designed exclusively for Li-ion/Li-polymer batteries. Its charge algorithm (trickle → pre-charge → CC → CV), voltage thresholds (e.g., 2.5–2.7V/cell UVLO), and JEITA zones assume lithium-based electrochemistry; use with LiFePO₄ or NiMH would require external supervision and is not supported.

How is thermal regulation implemented versus thermal shutdown?

Thermal regulation (configurable up to 120°C) linearly reduces charge current to maintain die temperature at the setpoint, allowing continued operation below shutdown. Thermal shutdown (150°C, fixed) forces immediate charge halt and BGATE/ACGATE disable. Both features use the same on-die temperature sensor but trigger distinct safety responses.

What external components are mandatory for basic operation?

Mandatory components include: four 10μF ceramics at IN, two 22μF ceramics at BATT, one 1μF ceramic at SYS, 4.7μF at VCC, 100nF bootstrap caps (BST1/SW1, BST2/SW2), 10kΩ pull-ups on SCL/SDA/INT/ACOK, and 1MΩ resistor from ACGATE to MOSFET source. No inductor or sense resistors are internal.
