Product details
Overview
MCP73213T-G6XI/MF from Microchip Technology is a dual-cell Li-Ion/Li-Polymer linear battery charge management controller with integrated pass transistor, current sense, input overvoltage protection (13V), and thermal regulation. It delivers constant-current/constant-voltage charging with factory-preset 8.40V output voltage, ±0.6% regulation accuracy across –5°C to +55°C, and supports fast charge currents from 130 mA to 1100 mA via external PROG resistor. It is used in ultra-mobile PCs, portable media players, and walkie-talkies requiring compact, cost-optimized charging.
For engineers reviewing the MCP73213T-G6XI/MF datasheet, MCP73213T-G6XI/MF pinout, MCP73213T-G6XI/MF application, or MCP73213T-G6XI/MF equivalent, key selection considerations include its DFN-10 (3×3 mm) package, 8.40V regulated output for 2-cell stacks, 10% preconditioning option, 6-hour elapse safety timer, and automatic recharge at 95% VREG - all verified for operation from –40°C to +85°C ambient.
Technical Context
The MCP73213T-G6XI/MF implements a full linear CC/CV charge algorithm with integrated P-channel MOSFET pass element (RDSON = 350 mΩ @ 105°C), enabling direct connection to 2-cell Li-ion batteries without external power switches. Its UVLO (4.15V start / 4.05V stop) and OVP (13V threshold with 150 mV hysteresis) ensure robust operation with low-cost wall adapters.
Charge sequencing is fully autonomous: preconditioning at 10% IREG triggers below factory-set VPTH/VREG = 71.5%, transitions to fast charge at 130–1100 mA, then enters CV mode at 8.40V, terminating when average current falls to 10% IREG or after 6 hours. STAT pin provides open-drain status signaling with Type 1 (On/Off) output behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-cell Li-ion linear charge management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP73213-A6S/MF | Identical 8.40V output, 10% precondition, 6-hr timer, 10% termination, and 95% auto-recharge - same factory preset as MCP73213T-G6XI/MF. | Same target applications; differs only in tape-and-reel packaging and date code format. | Select MCP73213-A6S/MF for standard reel delivery; MCP73213T-G6XI/MF is functionally identical with alternate marking. |
| BQ24075RGTR | Single-cell 4.2V output; no 2-cell support; lacks integrated OVP; requires external resistor network for current setting. | Not suitable for 8.4V dual-cell systems; requires redesign of feedback and protection circuitry. | Only consider if migrating to single-cell architecture; not a drop-in replacement for MCP73213T-G6XI/MF. |
Compared with MCP73213-A6S/MF, MCP73213T-G6XI/MF offers identical electrical and functional behavior with minor packaging variation, while BQ24075RGTR requires full schematic revision due to fundamental cell-count and protection architecture differences.

FAQ
What is the factory-preset charge voltage for MCP73213T-G6XI/MF?
The MCP73213T-G6XI/MF is factory configured for 8.40V regulated output voltage, with ±0.6% accuracy over –5°C to +55°C ambient temperature. This value is laser-trimmed during manufacturing and cannot be adjusted externally. The 8.40V setting targets nominal 4.2V-per-cell dual-stack Li-ion or Li-polymer batteries, ensuring safe and complete charging without overvoltage risk.
Does MCP73213T-G6XI/MF support automatic recharge, and at what threshold?
Yes, MCP73213T-G6XI/MF supports automatic recharge at 95% of its regulated output voltage (i.e., 95% × 8.40V = 7.98V). When battery voltage drops below this threshold in Charge Complete mode, the device automatically restarts the full CC/CV charge cycle. This behavior is fixed per factory preset and requires no external configuration.
What is the role of the PROG pin on MCP73213T-G6XI/MF beyond current programming?
On MCP73213T-G6XI/MF, the PROG pin serves dual functions: it sets fast charge current via resistor-to-VSS (130–1100 mA range), and acts as an enable/disable control. Applying >200 kΩ impedance (e.g., open circuit or high-Z MCU pin) forces MCP73213T-G6XI/MF into Standby mode with <150 μA quiescent current, halting all charging activity until impedance drops below threshold.
How does MCP73213T-G6XI/MF handle thermal regulation during charging?
MCP73213T-G6XI/MF continuously monitors die temperature and dynamically reduces fast charge current when thermal limits are approached. This regulation optimizes charge time while preventing junction overheating - critical for DFN-10 packages in enclosed portable devices. Thermal shutdown activates only as a secondary safety at 150°C, with 10°C hysteresis for recovery.
What status indication behavior does MCP73213T-G6XI/MF provide on the STAT pin?
MCP73213T-G6XI/MF implements Type 1 status output on the STAT pin: it drives low during Preconditioning, Fast Charge, and Constant Voltage modes, and goes high-impedance (open-drain) during Shutdown, Standby, and Charge Complete states. This allows direct LED driving with pull-up or MCU GPIO monitoring without additional logic.
