Product details
Overview
MP2722GRH-0000-Z 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 Bluetooth headphones and POS terminals.
For engineers reviewing the MP2722GRH-0000-Z datasheet, MP2722GRH-0000-Z pinout, MP2722GRH-0000-Z application, or MP2722GRH-0000-Z equivalent, key selection criteria include USB Type-C DRP autonomy, configurable 80mA–5A charging, 100mA–3.2A input current limiting, ±0.5% battery voltage regulation, and QFN-22 package integration for space-constrained wearable and portable designs.
Technical Context
The MP2722 implements a narrow-voltage DC (NVDC) power path with integrated 14mΩ battery MOSFET and 25mΩ high-side/low-side power switches, enabling seamless transition between input source and battery supply while minimizing system voltage droop. Its autonomous USB Type-C DRP engine performs CC1/CC2 detection, Rp/Rd identification, and Try.SNK/Try.SRC state machine execution without host intervention.
Charge control is fully I²C-configurable: battery regulation voltage (3.6V–4.6V), termination current (30mA–120mA), JEITA temperature windows (0°C–60°C), and switching frequency (750kHz–1.5MHz) are all register-mapped. The device also integrates boost-mode OTG capability with 5V–5.35V output, 3A current limit, and OCP for USB On-The-Go applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-cell USB-C DRP charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25618RTWR | Lower max charge current (3A vs. 5A); no integrated boost converter; uses separate NTC pins without JEITA zone flexibility. | Targeted at cost-sensitive mid-power wearables; lacks OTG capability and autonomous DRP toggle timing control. | Select when system-level OTG is unnecessary and JEITA profile complexity is reduced by design. |
| IP2326 | Fixed 4.2V regulation only; no I²C configurability for charge voltage or termination; no USB-C DRP - only sink-only mode. | Designed for basic USB-C charging in entry-tier accessories; no support for source or dual-role operation. | Choose only for fixed-function, non-DRP applications where I²C control and thermal customization are not required. |
Compared with BQ25618RTWR and IP2326, the MP2722GRH-0000-Z uniquely combines 5A charging, autonomous DRP, JEITA configurability, and integrated OTG boost - making it the only option supporting full-featured USB-C power negotiation and battery management in ≤15W portable systems.

FAQ
What USB Type-C specifications does the MP2722GRH-0000-Z comply with?
The MP2722GRH-0000-Z is compliant with USB Type-C 1.3 specification and supports USB Battery Charging Specification 1.2 (BC1.2) for legacy adapter detection. It implements full DRP functionality including try.SNK and try.SRC modes, CC1/CC2 detection, Rp/Rd identification, and VCONN sourcing per USB-IF requirements.
How is JEITA thermal profiling implemented on this device?
The MP2722GRH-0000-Z supports a fully customizable JEITA profile using two NTC inputs (NTC1 and PG/NTC2). Users configure four temperature thresholds (cold, cool, warm, hot) and associated charge/discharge actions via I²C registers. Thresholds are defined as percentages of VRNTC voltage, enabling precise mapping to 0°C–60°C ranges with hysteresis.
Can the MP2722GRH-0000-Z operate without an I²C host controller?
Yes - the MP2722GRH-0000-Z supports autonomous operation with factory-default register settings. DRP toggle, JEITA zones, charge voltage (4.2V), and termination current (120mA) are preconfigured. I²C is required only for customization (e.g., 4.35V charging, 30mA termination, or dynamic input current limiting).
What is the purpose of the STAT/IB pin's dual functionality?
The STAT/IB pin operates in two mutually exclusive modes: as an open-drain status indicator (LOW = charging, HIGH = idle/fault, blinking = error) or as a current-sense output sourcing 18.2–22.1μA per mA of battery current. Mode selection is controlled via I²C register, enabling either real-time charging state feedback or precision battery current monitoring.
Does the MP2722GRH-0000-Z support USB On-The-Go (OTG) functionality?
Yes - the MP2722GRH-0000-Z integrates a synchronous boost converter capable of delivering 5.08V–5.22V at up to 3A into capacitive loads up to 2mF. It includes output over-current protection, configurable output voltage, and automatic transition from buck to boost mode based on system demand and battery voltage.
What package thermal characteristics enable high-power operation in small form factors?
The QFN-22 (2.5mm × 3.5mm) package features an exposed thermal pad with θJC = 12°C/W and θJA = 50°C/W on a 4-layer PCB. Combined with integrated 14mΩ battery FET and 25mΩ power switches, this allows continuous 5A charging at ambient temperatures up to +85°C without external heatsinking in typical portable PCB layouts.
How does the NVDC architecture improve system performance compared to traditional charging solutions?
The NVDC architecture maintains a low-impedance path between input source and system rail (SYS), allowing immediate system power-up even with depleted battery. It eliminates system brownouts during charge initiation and enables simultaneous charging and system operation without voltage sag - critical for always-on portable devices like POS terminals and Bluetooth speakers.
