Monolithic Power Systems Inc. MP2650GV-0200-Z

Overview

MP2650GV-0200-Z from Monolithic Power Systems is an I²C-controlled, dual-mode buck/boost battery charger IC optimized for 2-cell Li-ion/Li-polymer battery packs (8.4V nominal). It integrates all power MOSFETs, supports up to 5A charge/discharge current, delivers NVDC power path management with system voltage regulation down to ±5mV tracking error, and enables USB OTG output up to 5V/3A. It is deployed in portable computing and imaging systems requiring seamless battery-to-system power handoff.

For engineers reviewing the MP2650GV-0200-Z datasheet, MP2650GV-0200-Z pinout, MP2650GV-0200-Z application, or MP2650GV-0200-Z equivalent, key selection considerations include its 2-cell–specific factory configuration (-0200), integrated NVDC FET, configurable 600–1250kHz switching frequency, thermal regulation at 120°C, and IMVP8-compliant PSYS/IAM/IBM analog monitoring outputs.

Technical Context

The MP2650 operates in adaptive buck or boost charging mode based on input voltage (4–21V) and cell count-here fixed for 2-cell (8.4V max) via factory-programmed register defaults. Its NVDC architecture uses a dedicated system-side FET (Q5, R_DS(on) = 11mΩ) to regulate SYS voltage independently of battery state, enabling uninterrupted operation during deep discharge or battery removal.

Charging control is fully I²C-configurable: input current limit (up to 5A), charge voltage (default 8.40V ±63mV), safety timer (up to 12 hrs), and JEITA-compliant NTC temperature thresholds are set via 16-bit registers. Fault reporting includes real-time status flags for OVP (VIN, BATT, SYS), thermal shutdown (150°C), and short-circuit detection in both charge and OTG modes.

FAQ

What does the "-0200" suffix indicate in MP2650GV-0200-Z?

The "-0200" denotes factory-programmed register defaults optimized for 2-cell (8.4V) battery packs, including VBATT_REG = 8.40V, pre-charge threshold = 6.20V, and JEITA cold/warm thresholds aligned to 2S thermal profiles. This eliminates manual I²C initialization for basic operation.

How does NVDC power path management function in this IC?

NVDC uses an integrated 11mΩ SYS-to-BATT FET (Q5) to regulate the system rail within ±5mV of the target voltage, independent of battery state. When the battery is depleted or removed, the IC sustains SYS from the input source without interruption-critical for instant-on user experience.

Can MP2650GV-0200-Z support USB-C Power Delivery input?

Yes-it accepts 4–21V input, covering USB-C PD profiles (5V/9V/15V/20V). The 28V transient rating (20ns) and input OVP (24V typ.) ensure robustness against PD negotiation spikes and cable-induced surges without external protection.

What is the role of the PSYS, IAM, and IBM pins in system design?

PSYS delivers a 100µA full-scale current source proportional to total system power; IAM provides 250mV/A input current sensing; IBM outputs 125mV/A (charge) or 62.5mV/A (discharge) battery current. Together, they replace three separate current-sense amplifiers in IMVP8-compliant platforms.

Does this IC require external MOSFETs for charging or OTG operation?

No-all power MOSFETs-including buck (Q1/Q2), boost (Q3/Q4), and NVDC path (Q5)-are monolithically integrated. The only external power components needed are inductors, capacitors, and current-sense resistors, enabling a complete 2S charger in <120 mm² PCB area.

How is thermal regulation implemented, and what triggers PROCHOT assertion?

Thermal regulation activates at 120°C to reduce charge current; hard shutdown occurs at 150°C. PROCHOT asserts open-drain at 5.84V SYS undervoltage or 12A battery discharge overcurrent-providing hardware-level CPU throttling compatible with Intel mobile platforms.

Is the I²C interface required for basic charging functionality?

No-factory-configured defaults (e.g., 8.40V regulation, 5A limit, 12hr timer) enable plug-and-play operation. I²C is optional for dynamic reconfiguration, telemetry readback, fault diagnostics, and fine-grained JEITA profile tuning during runtime.
