Monolithic Power Systems Inc. MP2720GRH-0000-P

Overview

MP2720GRH-0000-P from Monolithic Power Systems is a 2.5A, I²C-controlled, single-cell Li-ion/Li-polymer buck charger IC with NVDC power path architecture, integrated 15mΩ battery MOSFET, configurable 750kHz–1.5MHz switching frequency, and dual-role boost converter supporting USB OTG up to 3A. It delivers ±0.5% battery voltage regulation and operates in portable audio devices requiring fast, thermally robust charging.

For engineers reviewing the MP2720GRH-0000-P datasheet, MP2720GRH-0000-P pinout, MP2720GRH-0000-P application, or MP2720GRH-0000-P equivalent, this page provides verified pin functions, JEITA-compliant thermal management, shipping-mode discharge current (8.5μA), I²C-configurable charge current (80mA–2.5A), and input current limit (100mA–3.2A) - all critical for wearable and USB-powered embedded designs.

Technical Context

The MP2720 implements a narrow-voltage DC (NVDC) power path with integrated RB-FET, HS-FET, LS-FET, and BATTFET, enabling seamless system power-up from battery or input while minimizing voltage headroom loss. Its dual-loop control regulates both input current (I_{IN_LIM}) and battery charge current (I_CC) independently via I²C registers.

It integrates a fully configurable JEITA profile using two NTC inputs (NTC1/NTC2), die temperature regulation (60°C–120°C), and a dedicated boost converter with 5V–5.35V output, OCP, and 2mF capacitive load drive capability - supporting source-mode operation without external circuitry.

FAQ

What is the minimum termination current setting supported by MP2720GRH-0000-P?

The MP2720GRH-0000-P supports a configurable termination current as low as 30mA via I²C register programming. This setting is validated for use with small-capacity batteries (e.g., 150mAh earbuds), ensuring full charge without overcharge risk or premature cutoff due to inaccurate current sensing.

Does MP2720GRH-0000-P support USB Battery Charging Specification 1.2?

Yes - the MP2720GRH-0000-P implements full BC1.2 D+/D− detection logic, identifying SDP, CDP, and DCP sources. It also supports non-standard adapter detection using three voltage windows (1.2V, 2.0V, 2.7V), enabling reliable charging from legacy wall adapters and automotive USB ports.

How does the NVDC power path improve system performance?

The NVDC architecture maintains a low-impedance path between battery and system (SYS) rail, allowing the system to operate seamlessly during input plug/unplug transitions. Unlike conventional architectures, it avoids brownouts by preventing SYS voltage collapse when input is removed - critical for real-time audio/video applications.

Can MP2720GRH-0000-P power USB peripherals without external components?

Yes - its integrated boost converter delivers 5.0–5.35V at up to 3A with built-in OCP and 2mF capacitive load drive. No external inductor, diode, or feedback resistors are needed for standard USB OTG operation, reducing BOM count and PCB area versus discrete solutions.

What thermal protection mechanisms are implemented?

The MP2720GRH-0000-P features die temperature regulation (configurable 60°C–120°C), thermal shutdown at 150°C with 30°C hysteresis, and JEITA-compliant NTC monitoring on two independent inputs. These layers prevent overheating during fast charging in thermally constrained enclosures.

Is remote battery voltage sensing supported?

Yes - the BATTSNS pin enables Kelvin connection to the battery pack's positive terminal, compensating for PCB trace resistance. This ensures ±0.5% battery voltage regulation accuracy even with >100mΩ path resistance, critical for precision charging in multi-layer boards.

What is the purpose of the RST pin beyond shipping mode wake-up?

When VIN is absent, pulling RST low for 8–12ms forces BATTFET off for 250–400ms (tSYS_RST), then re-enables it - effectively resetting the SYS power rail without removing the battery. This recovers from latch-up conditions caused by system overloads or short circuits.
