Product details
Overview
MP2723GQC-0000-Z from Monolithic Power Systems is a 3A, I²C-controlled switch-mode battery charger IC for single-cell Li-ion/Li-polymer batteries, featuring NVDC power path management, USB OTG boost (up to 1.5A at 5V), and integrated ADC for voltage/current/temperature monitoring. It operates from 3.7V–5.5V input, delivers 92% charge efficiency at 3A, and supports automatic charging cycle initiation and termination.
For engineers reviewing the MP2723GQC-0000-Z datasheet, MP2723GQC-0000-Z pinout, MP2723GQC-0000-Z application, or MP2723GQC-0000-Z equivalent, key selection considerations include NVDC system-level power path behavior, I²C-configurable charge voltage (3.4–4.67V) and current (320–3000mA), USB input type detection (SDP/CDP/DCP), thermal regulation (112°C), and shipping mode control via DISC pin with 13µA battery leakage.
Technical Context
The MP2723 implements a synchronous buck topology with integrated high-side (37mΩ) and low-side (37mΩ) MOSFETs, operating at 1.35MHz nominal switching frequency. Its NVDC architecture enables instant-on operation with no or deeply discharged battery by regulating SYS independently of BATT, while supporting ideal diode mode during battery-supplement operation.
USB OTG functionality is implemented via internal boost converter with adjustable 4.8–5.5V output and I²C-configurable current limit (0.5–1.8A). Battery safety is enforced through JEITA-compliant NTC monitoring (cold/cool/warm/hot thresholds), configurable charge timer, over-voltage protection (103.5% of VBATT_REG), and thermal shutdown at 150°C with 20°C hysteresis.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 6, 7 | PGND | Power ground return for high-current paths (IN, SW, BATT, SYS); requires low-inductance connection to thermal pad. |
| 2 | IN | Main 3.7–5.5V input supply; connects to USB port or wall adapter; requires 1µF ceramic decoupling near pin. |
| 3 | PMID | Internal power rail feeding high-side gate driver; bypassed with 10µF capacitor to PGND for stable bootstrap operation. |
| 4 | SW | Switching node between integrated high-side and low-side MOSFETs; connects to external 1µH inductor. |
| 8 | BST | Bootstrap capacitor connection (47nF to SW); enables high-side FET gate drive above PMID voltage. |
| 9 | STAT | Open-drain status indicator; signals charge state (trickle/pre-charge/CC/CV/complete/fault) to host MCU. |
| 10 | INT | Open-drain interrupt output; asserts on fault conditions (OV/OT/NTC out-of-range/timer expiry) for real-time host response. |
| 11 | NTC | Analog input for NTC thermistor; used with VNTC reference to implement JEITA-compliant battery temperature monitoring. |
| 12 | VNTC | Reference voltage source (≈1.2V) for NTC divider network; sets cold/cool/warm/hot thresholds via resistor ratios. |
| 13–14 | VREF | 3.6V LDO output; powers external logic or serves as ADC reference; requires 10µF ceramic decoupling to AGND. |
| 15 | AGND | Analog ground reference for ADC, NTC, and internal comparators; must be separated from PGND and tied at single point. |
| 16 | SYS | System power rail output; regulated independently of battery via NVDC path; supplies main SoC and peripherals. |
| 17 | BATT | Battery positive terminal connection; routes charge/discharge current through integrated 14mΩ BATFET. |
| 18 | CE | Active-low hardware charge enable; overrides I²C register setting; pulled low to initiate charging sequence. |
| 19–20 | SCL/SDA | I²C interface pins (1.8V logic); support 400kHz clock for full configuration of charge parameters, protections, and status reads. |
| 21 | DISC | Dedicated battery disconnect control; pulsed low for 8s enters shipping mode (13µA IBATT leakage); short pulse triggers system reset. |
| 22 | OTG | Hardware OTG enable/disable; driven low by host to suspend boost operation during system-level power management events. |
| 23 | ILIM | Analog input for resistor-programmable input current limit; sets maximum IIN independent of I²C register value. |
| 24–25 | DP/DM | USB data line pair; performs USB type detection (SDP/CDP/DCP) via built-in current sources and comparators. |
| 26 | DP | Positive USB data line; includes 7–14µA DCD current source and 70–130µA sink capability for enumeration. |

FAQ
What USB input types does MP2723GQC-0000-Z detect automatically?
The MP2723 detects USB Standard Downstream Port (SDP), Charging Downstream Port (CDP), Dedicated Charging Port (DCP), and non-standard adapters using its integrated DP/DM analog front-end with current sources and voltage comparators. Detection occurs at power-up and during dynamic insertion, enabling appropriate input current limit selection without host software.
How does the NVDC power path improve system reliability in portable devices?
NVDC ensures the SYS rail remains powered even with zero or deeply discharged battery by regulating directly from the input source. This enables instant-on functionality, prevents system brownouts during battery swap or depletion, and allows simultaneous charging and system operation without voltage droop on the main SoC rail.
Can MP2723GQC-0000-Z operate without I²C communication?
Yes-the MP2723 includes a factory-default register map that enables full autonomous charging (trickle → pre-charge → CC → CV → terminate → auto-recharge) and USB OTG operation without I²C initialization. I²C is required only for customization of voltage/current limits, JEITA thresholds, and advanced status reporting.
What is the purpose of the DISC pin beyond shipping mode activation?
Beyond entering shipping mode (13µA battery leakage), the DISC pin provides hardware-triggered system reset: a short low pulse (≤100ms) forces a controlled restart of the host processor by asserting a reset signal through internal logic, eliminating need for external reset ICs in compact designs.
How does the integrated ADC reduce BOM cost compared to discrete sensing solutions?
The 8-bit ADC monitors six critical parameters-VIN, VBAT, VSYS, ICHG, IIN, and NTC voltage-with dedicated input channels and internal references. This eliminates external op-amps, current-sense amplifiers, voltage dividers, and NTC bias networks, reducing component count by up to 9 parts and associated layout area.
What thermal protection mechanisms are implemented in MP2723GQC-0000-Z?
Thermal protection includes junction temperature regulation at 112°C (frequency foldback), thermal shutdown at 150°C with 20°C hysteresis, and watchdog monitoring of I²C activity to detect communication failure that could prevent thermal alerts from reaching the host.
Is MP2723GQC-0000-Z RoHS and REACH compliant?
Yes-MP2723GQC-0000-Z is lead-free, halogen-free, and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation is available on the Monolithic Power Systems website under Quality Assurance.
