Product details
Overview
MP2762AGV-0000-Z from Monolithic Power Systems is a fully integrated I²C-controlled buck/boost battery charger IC for 2-cell series (2S) Li-ion/Li-polymer packs, supporting up to 6A charge/discharge current, NVDC power path management, and 5V/3A USB OTG functionality. It operates from 4V–21V input, integrates all power MOSFETs, and delivers precise battery regulation at 8.4V with ±63mV accuracy under typical conditions.
For engineers reviewing the MP2762AGV-0000-Z datasheet, MP2762AGV-0000-Z pinout, MP2762AGV-0000-Z application, or MP2762AGV-0000-Z equivalent, key selection considerations include dual-mode (buck/boost) charging architecture, real-time analog monitoring via PSYS/IAM/IBM pins, IMVP8-compliant system power control, thermal regulation at 120°C, and configurable safety timers for dead-battery recovery.
Technical Context
The MP2762A implements a dual-phase interleaved buck converter (SW1/SW2) for high-efficiency charging above 8.5V input and a synchronous boost converter (SW3) for charging below 5.75V input-enabling seamless operation across wide-input adapters and USB sources. Its NVDC architecture maintains regulated SYS voltage (6.87–7.52V) independent of battery state, allowing uninterrupted system operation even with depleted or absent batteries.
Integrated analog monitors (PSYS, IAM, IBM) provide real-time proportional current/voltage outputs compliant with IMVP8 specifications, while the PROCHOT pin delivers processor-level thermal or overcurrent alerts. All protection-including input/battery/system OVP, NTC-based JEITA temperature profiling, and dual-stage charge timers-is configurable via I²C registers (e.g., REG00H–REG12H), enabling fine-grained system-level power policy enforcement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck/boost charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25792RTWR | Single-phase buck-boost; no integrated OTG boost; 4.5V–24V input; 5A max charge; uses SMBus instead of I²C | Lacks native 5V/3A OTG output and PSYS analog telemetry - requires external boost IC and ADC for system power monitoring | Select when cost-sensitive designs prioritize SMBus compatibility and do not require integrated OTG or IMVP8 telemetry |
| ISL9241IRZ-T7A | 3.2V–20V input; 6.4A charge; includes integrated fuel gauge; supports 3S/4S but not 2S-optimized NVDC | Higher cell-count flexibility but less precise 2S regulation; lacks dedicated PROCHOT and PSYS pins for IMVP8 systems | Select when multi-cell support and fuel-gauge integration outweigh need for 2S-specific NVDC optimization and IMVP8 compliance |
Compared with BQ25792RTWR and ISL9241IRZ-T7A, MP2762AGV-0000-Z uniquely combines 2S-optimized NVDC regulation, integrated 5V/3A OTG, and IMVP8-compliant analog telemetry in a single QFN-30 package - reducing system-level component count and simplifying thermal/power policy implementation.

FAQ
What input voltage ranges trigger buck vs. boost charging modes?
The MP2762AGV-0000-Z automatically enters buck charging mode when input voltage exceeds 8.5V and boost charging mode when input falls below 5.75V. Between 5.75V and 8.5V, the device remains in standby until input crosses one threshold. This hysteresis prevents mode oscillation and is fixed in silicon per datasheet Rev. 1.1 Section 8.2.
How does the NVDC power path maintain system operation with a dead or removed battery?
NVDC regulation holds the SYS rail at a programmable 6.87V–7.52V (via REG07H) directly from the input source, independent of battery voltage. When the battery is depleted or disconnected, the internal power FETs route input power to SYS while disabling battery discharge paths - ensuring uninterrupted system power without brownouts.
Can the PSYS, IAM, and IBM analog outputs be used without calibration?
Yes - PSYS (100µA/W full-scale), IAM (250mV/A + 100mV offset), and IBM (125mV/A charge, 62.5mV/A discharge) are factory-trimmed and specified with guaranteed gain/offset tolerances. No external calibration is required for IMVP8-compliant system power monitoring or current sensing per datasheet Electrical Characteristics Table.
What protection features are configurable via I²C versus hardwired?
I²C configures all safety thresholds (input/battery OVP, charge timers, JEITA temperature windows, OTG limits) and enables/disables functions (PROCHOT, PSYS, ADC). Hardwired protections include absolute maximum ratings (e.g., 28V/20ns input surge), thermal shutdown at 150°C, and bootstrap capacitor undervoltage lockout - which remain active regardless of register settings.
Does the MP2762AGV-0000-Z support battery detection for pack insertion/removal?
Yes - the NTC pin (Pin 3) can be configured via I²C as BATDET to detect battery presence. When enabled, the IC monitors voltage at this pin and asserts a fault if it falls below 1.6V (±10mV hysteresis), allowing the host system to detect hot-swap events and initiate safe power-state transitions.
What is the role of the VMAX_BST pin, and how must it be decoupled?
VMAX_BST is the charge pump output that supplies gate drive voltage for high-side MOSFETs. It must be decoupled with a 100nF ceramic capacitor in series with a 100Ω resistor to PGND, placed adjacent to the IC. This RC network suppresses switching noise and ensures stable bootstrap operation during high-frequency (600kHz–1MHz) buck/boost transitions.
How does the PROCHOT signal interact with system-level thermal management?
PROCHOT is an open-drain output that pulls AGND when triggered by die temperature ≥120°C (REG05H), input overcurrent ≥8.2A, or battery discharge overcurrent ≥12A. The host CPU monitors this signal and initiates throttling per IMVP8 spec - providing hardware-level, sub-100µs response to critical thermal/electrical faults without software latency.
