Monolithic Power Systems Inc. MP2722GRH-0000-P

Overview

MP2722GRH-0000-P from Monolithic Power Systems is a 5A, single-cell Li-ion/Li-polymer buck charger with integrated USB Type-C DRP detection, NVDC power path architecture, I²C programmability, and JEITA-compliant thermal management. It delivers up to 5A charge current, supports 3.9V–16V input, and enables dual-role power negotiation (try.SNK/try.SRC) in portable devices like Bluetooth headphones and POS terminals.

For engineers reviewing the MP2722GRH-0000-P datasheet, MP2722GRH-0000-P pinout, MP2722GRH-0000-P application, or MP2722GRH-0000-P equivalent, key selection considerations include its QFN-22 package, 8.5μA shipping-mode discharge, ±0.5% battery voltage regulation, configurable 750kHz–1.5MHz switching frequency, and dual NTC inputs for precision thermal profiling.

Technical Context

The MP2722 implements an NVDC architecture where the internal 14mΩ battery MOSFET decouples system load from battery charging, enabling seamless transition between input power and battery supply without system brownout. Its autonomous USB Type-C DRP engine performs CC1/CC2 detection, Rp/Rd identification, and toggles between sink/source roles within 70–90ms.

Charge control is fully I²C-configurable: battery voltage (3.6–4.6V), charge current (80mA–5A), input current limit (100mA–3.2A), and JEITA temperature windows are set via registers. The device integrates a 15mΩ low-R_DS(ON) battery FET, boost converter (5V–5.35V, up to 3A), and dual analog NTC inputs with independent cold/cool/warm/hot thresholds.

FAQ

What USB Type-C features does MP2722GRH-0000-P support?

MP2722GRH-0000-P supports full USB Type-C 1.3 compliance including autonomous DRP toggle, try.SNK/try.SRC modes, CC1/CC2 detection, Rp/Rd identification, and BC1.2/non-standard adapter recognition. It requires no external CC controller or MCU firmware for basic DRP operation.

How does the NVDC architecture improve system reliability?

The NVDC architecture uses an internal 14mΩ battery FET to decouple the SYS rail from the battery. This ensures continuous system power even when the battery is deeply discharged or removed, eliminating brownouts during charge/discharge transitions and improving user experience in portable devices.

Can MP2722GRH-0000-P support JEITA-compliant charging for medical-grade devices?

Yes-MP2722GRH-0000-P supports a fully customizable JEITA profile with four independently configurable temperature thresholds (cold/cool/warm/hot), hysteresis, and action definitions. Its dual NTC inputs and ±0.5% battery voltage accuracy meet stringent requirements for medical and industrial Li-ion applications.

What is the purpose of the STAT/IB pin beyond charge status indication?

STAT/IB serves dual functions: as an open-drain status output (LOW = charging, HIGH = idle/fault, blinking = error), and as a current-sense output (IB) sourcing 20μA per mA of battery current. This enables real-time battery current telemetry without a shunt resistor or external amplifier.

Does MP2722GRH-0000-P require external components for USB-C DRP operation?

No-MP2722GRH-0000-P integrates all USB-C DRP functions: CC logic, Rp/Rd detection, VCONN generation (via PMID), and DRP state machine. Only passive components (pull-down resistors on CC1/CC2, bypass caps) are required; no external MCU or CC controller is needed for basic DRP functionality.

How is shipping mode activated and exited?

Shipping mode is entered automatically after 12–15 seconds of no input voltage and disabled battery FET. It is exited by pulling the RST pin low for 0.9–1.3 seconds while VIN remains absent, which re-enables the battery FET and restores SYS power-enabling "wake-on-plug" behavior in retail devices.

What boost converter capabilities does MP2722GRH-0000-P provide for OTG?

The integrated boost converter delivers 5V–5.35V output with up to 3A current limit, OCP, and ability to drive up to 2mF capacitive loads. It supports USB On-The-Go (OTG) by powering peripherals directly from the battery, eliminating the need for a discrete boost IC in portable accessories.
