Product details
Overview
MP2667GG-0000-P from Monolithic Power Systems is a single-cell Li-ion/Li-polymer linear battery charger with integrated I²C interface, power path management, and programmable charge parameters. It delivers up to 1000mA fast charge current, ±0.5% battery voltage regulation accuracy at 4.2V, and operates from 4.35–5.5V USB input. Used in wearable devices and smartwatches, it enables simultaneous system power delivery and battery charging while preventing over-discharge via programmable 2.4–3.1V battery UVLO.
For engineers reviewing the MP2667GG-0000-P datasheet, MP2667GG-0000-P pinout, MP2667GG-0000-P application, or MP2667GG-0000-P equivalent, key selection criteria include I²C-programmable input current limit (77–993mA), thermal regulation threshold (120°C), shipping mode battery disconnect, NTC-based temperature monitoring, and dual-path power management with 300mΩ IN→SYS LDO FET and 100mΩ BATT→SYS switch.
Technical Context
The MP2667 implements a direct power path architecture using two integrated MOSFETs: a 300mΩ LDO FET between IN and SYS for regulated system supply, and a 100mΩ battery FET between BATT and SYS for bidirectional energy flow. This decouples charging current from system load current, enabling precise charge termination independent of load transients.
Its I²C-controlled charge engine supports three-phase charging-pre-charge (6–25mA), constant-current fast charge (26–1049mA), and constant-voltage regulation (3.600–4.545V)-with programmable safety timer (5–20 hrs), auto-recharge thresholds (140–370mV), and battery UVLO hysteresis (227mV).

Pinout & Package
MP2667GG-0000-P is housed in an ultra-compact 10-pin QFN package (2mm × 2mm, 0.4mm pitch) with exposed thermal pad for enhanced power dissipation in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Power Input | Main 4.35–5.5V USB input; requires ≥1μF ceramic capacitor to GND for stability and transient suppression. |
| 2 NTC | Analog Input | Connects to NTC thermistor divider; enables hot/cold battery temperature monitoring and charge suspension outside programmed window. |
| 3 INT | Open-Drain Output | Interrupt signal for charge status/faults; pull-low >8s disconnects battery from system for shipping mode activation. |
| 4 VDD | Internal Bias Supply | Internal LDO output; requires 0.1μF decoupling cap to GND; no external loading permitted. |
| 5 GND | Ground Reference | Common return for all analog/digital/power paths; must be low-impedance connection to PCB ground plane. |
| 6 SCL | I²C Clock | Bi-directional clock line; requires 10kΩ pull-up to logic rail (1.8V or 3.3V) for proper I²C timing. |
| 7 SDA | I²C Data | Bi-directional data line; requires 10kΩ pull-up to same logic rail as SCL for bus integrity. |
| 8,9 BATT | Battery Terminal | Direct connection to single-cell Li-ion anode; requires local ceramic capacitor to GND for low-ESR filtering. |
| 10 SYS | System Power Output | Regulated 4.85–5.15V system rail; powers host MCU/load independently of battery state during charging or supplement mode. |

FAQ
What is the maximum allowable input voltage for MP2667GG-0000-P?
The absolute maximum input voltage is +13V, but the recommended operating range is 4.35V to 5.5V for USB compatibility. Input over-voltage protection triggers at 5.85–6.15V (rising edge), and recovery occurs after a 367mV hysteresis drop. Exceeding 13V risks permanent damage to the IN pin ESD structure.
How does the MP2667 handle system power when the battery is deeply discharged?
It prioritizes system startup using the IN→SYS LDO FET-even with a 0V battery-regulating VSYS to 4.85–5.15V. The battery FET remains off until VBATT rises above the pre-charge threshold (2.8–3.1V), ensuring stable system operation before initiating safe pre-charge.
Can the MP2667 operate without an NTC thermistor?
Yes, the NTC pin is optional. If left unconnected or tied to GND/VIN, temperature monitoring is disabled and charging proceeds normally. However, omitting NTC forfeits JEDEC JESD47-compliant thermal safety for Li-ion cells, and is not recommended for production in thermally isolated enclosures.
What happens during input power removal while the system is active?
Upon IN removal, the battery FET (Q2) fully turns on within milliseconds, supplying system load directly from the battery. The SYS rail remains uninterrupted, and the device enters supplement mode-maintaining VSYS regulation down to VBATT_UVLO threshold (programmable 2.4–3.1V).
Is the MP2667GG-0000-P compatible with lithium iron phosphate (LiFePO₄) batteries?
No. The MP2667 is optimized for single-cell Li-ion/Li-polymer chemistry with 3.6–4.545V regulation range. LiFePO₄ requires ~3.6V nominal and 3.65V termination-outside its minimum 3.600V programmable VBATT_REG setting-and lacks the low-voltage cutoff profile needed for LiFePO₄ safety.
How is shipping mode activated and verified?
Shipping mode is activated by pulling the INT pin low for >8 seconds, which disables the BATT→SYS FET and reduces quiescent current to ≤5µA. Verification is confirmed by measuring <1µA current between BATT and SYS pins and observing VSYS = 0V when IN is absent and battery is connected.
Does the MP2667 support USB BC1.2 or proprietary fast-charge protocols?
No. It accepts only standard 5V USB power and regulates input current via I²C programming. It does not negotiate voltage or current with upstream chargers (e.g., no D+/D− detection), nor does it support Qualcomm Quick Charge or USB PD negotiation.
