Product details
Overview
MP2762AGV-0000-P from Monolithic Power Systems is a highly integrated I²C-controlled buck/boost battery charger IC for 2-cell series (2S) Li-ion/Li-polymer packs, featuring NVDC power path management, USB OTG support up to 5V/3A, and full thermal regulation at 120°C. It integrates all power MOSFETs, supports 4V–21V input, delivers up to 6A charge current, and enables system operation even with depleted or absent battery via regulated SYS rail.
For engineers reviewing the MP2762AGV-0000-P datasheet, MP2762AGV-0000-P pinout, MP2762AGV-0000-P application, or MP2762AGV-0000-P equivalent, key selection considerations include dual-mode (buck/boost) charging architecture for wide-input adapters, real-time current/voltage monitoring via IAM/IBM/PSYS analog outputs, IMVP8-compliant system power control, and configurable safety timers and temperature thresholds per JEITA profiles.
Technical Context
The MP2762AGV-0000-P implements a dual-phase interleaved buck converter (SW1/SW2) and single-phase boost converter (SW3) with independent bootstrap circuits (BST1/BST2/BST3), enabling seamless mode transition between buck (VIN > 8.5V) and boost (VIN < 5.75V) operation. Its NVDC architecture maintains SYS voltage within ±100mV of programmed setpoint regardless of battery state.
It provides three dedicated analog monitoring outputs-PSYS (system power proportional current source), IAM (input current sense, 250mV/A), and IBM (battery current sense, ±125mV/A charging / ±62.5mV/A discharging)-and supports processor hot throttling via open-drain PROCHOT with programmable triggers for input overcurrent (8.2A), battery discharge overcurrent (12A), and system undervoltage (5.84V).

FAQ
What input voltage ranges trigger buck vs. boost charging modes?
The MP2762AGV-0000-P automatically enters buck charging mode when input voltage exceeds 8.5V (typical) and boost charging mode when input falls below 5.75V (typical). Between these thresholds, the device operates in hybrid or transitional states governed by internal control loops and I²C-configured VIN_MIN settings. This behavior is confirmed in the Electrical Characteristics table (REG01H register settings) and Typical Application Circuit documentation.
How does the NVDC power path maintain system operation during battery removal?
The NVDC architecture regulates the SYS rail independently using input power, bypassing the battery entirely. When the battery is removed or fully depleted, the IC sustains SYS at the programmed voltage (e.g., 7.0V ±100mV) by sourcing current directly from IN through internal FETs (Q1–Q4), verified by the VSYS_REG_MIN specification (6.87–7.11V) and battery-absent operation test data in the datasheet.
Can the PSYS, IAM, and IBM analog outputs drive standard ADC inputs directly?
Yes - PSYS delivers a 100µA full-scale current source compatible with typical 10kΩ–100kΩ ADC input impedances; IAM outputs 0.1–1.2V (250mV/A +100mV offset) and IBM outputs 0–0.6V (charging) or 0–0.5V (discharging) with defined offsets, all within standard 0–3.3V or 0–5V ADC ranges. These values are specified in the Electrical Characteristics tables on pages 8–11 of the Rev. 1.1 datasheet.
What is the role of the VMAX_BST pin and how must it be decoupled?
VMAX_BST is the charge pump output that generates the gate drive voltage for high-side FETs in buck mode. It must be decoupled with a 100nF ceramic capacitor in series with a 100Ω resistor to PGND, placed adjacent to the IC, as explicitly shown in the Pin Functions section (page 5) and Package Reference diagram. This configuration suppresses ringing and ensures stable bootstrap operation.
Does the MP2762AGV-0000-P support battery fuel gauge integration?
No - the MP2762AGV-0000-P does not include Coulomb counting, voltage-based state-of-charge estimation, or SMBus/Gauge interface. It provides raw current-sense outputs (IAM/IBM) and status registers for external fuel gauge ICs (e.g., MAX17055) to process, but lacks on-chip fuel gauging functionality, as confirmed by absence of related registers or features in the Register Map and Feature List.
How is thermal regulation implemented and what is its impact on charge current?
Thermal regulation actively limits die temperature to 120°C (fixed threshold) by reducing charge current in real time, distinct from thermal shutdown at 150°C. This is achieved via internal thermal feedback loop adjusting PWM duty cycle, documented in the Absolute Maximum Ratings and Electrical Characteristics (TJ_REG = 120°C). Efficiency curves show sustained >85% operation at 6A/15V input even at elevated ambient temperatures.
Is the OTG function capable of simultaneous charging and discharging?
No - OTG mode disables battery charging. When OTG is enabled (via register or OTG pin assertion), the device enters reverse power flow: battery discharges to generate 5V on SYS rail, and input charging path is blocked. This functional separation is enforced in hardware and verified in the Functional Description section (page 1) and OTG Operation Electrical Characteristics (page 11).
