Product details
Overview
MCP73213T-G6AI/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 (13 V), and thermal regulation. It delivers factory-preset 8.40 V charge voltage, 10% preconditioning, 32-minute precondition timer, 6-hour elapse safety timer, and 10% end-of-charge current ratio - optimized for portable media players and ultra-mobile PCs.
For engineers reviewing the MCP73213T-G6AI/MF datasheet, MCP73213T-G6AI/MF pinout, MCP73213T-G6AI/MF application, or MCP73213T-G6AI/MF equivalent, this page provides verified technical context, exact pin functions, real-world design meanings of specifications, and two validated alternative parts for dual-cell Li-ion charging systems requiring ±0.6% voltage accuracy, –40°C to +85°C operation, and DFN-10 packaging.
Technical Context
The MCP73213T-G6AI/MF implements a full CC/CV charge algorithm with factory-trimmed 8.40 V regulation, 13 V input OVP, and 4.15 V UVLO. Its internal P-channel MOSFET (RDS(on) = 350 mΩ) enables direct battery connection without external power switches.
Charge control is resistor-programmable (130–1100 mA via PROG pin), with automatic transition from preconditioning (10% IREG) to fast charge, then constant-voltage mode, and termination at 10% IREG or after 6 hours. Thermal regulation activates before die temperature reaches 150°C, suspending current to maintain reliability under high ambient or power-dissipation conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 8.40 V ±0.6% over –5°C to +55°C - ensures safe, full capacity charging of 2-cell Li-ion packs without overvoltage stress. |
| Input OVP Threshold | 13.0 V (±0.2 V) - protects against wall-adapter spikes and enables use in cost-sensitive, unregulated supply environments. |
| Fast Charge Current Range | 130–1100 mA set by single PROG resistor - supports flexible battery capacity scaling (e.g., 350 mA for 500 mAh, 800 mA for 1200 mAh). |
| End-of-Charge Termination | 10% of fast charge current - balances full charge completion with cycle life preservation for consumer Li-ion cells. |
| Preconditioning | Enabled at 10% IREG, threshold = 71.5% of VREG - safely recovers deeply discharged batteries before CC mode. |
| Thermal Regulation | Active current limiting above ~110°C - maintains continuous charging under sustained load while preventing thermal runaway. |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - enables compact PCB layout and efficient heat dissipation in space-constrained devices. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP), rated for –40°C to +85°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2) | Battery management input supply | Accepts 4.2–13 V input; 18 V absolute max; powers internal circuitry and gate drive; bypass with ≥1 μF to VSS. |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to 2-cell battery positive; regulates voltage/current to battery terminals. |
| NC (Pins 5, 6) | No connection | Unbonded pins; must be left floating or grounded per layout best practice - no electrical function. |
| STAT (Pin 7) | Status output | Open-drain indicator: low during active charge, high-Z at completion; drives LED or MCU GPIO with pull-up. |
| VSS (Pins 8, 9) | 0 V reference | Common ground return for VDD, VBAT, and PROG; must connect to battery negative and input supply ground. |
| PROG (Pin 10) | Current regulation & enable | Sets fast charge current via resistor to VSS; >200 kΩ impedance places device in standby mode. |
| EP (Pin 11) | Exposed thermal pad | Internally connected to VSS; requires PCB copper pour and multiple vias for effective thermal conduction to inner layers. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | Eliminates need for external MOSFET and gate driver - reduces BOM count and PCB area in portable designs. |
| Input overvoltage protection | 13 V clamping with 150 mV hysteresis - prevents damage from low-cost AC adapters and plug/unplug transients. |
| Factory-preset charge parameters | 8.40 V regulation, 10% precondition, 6 hr elapse timer, 10% termination - removes configuration firmware or external logic. |
| Thermal regulation + shutdown | Gradual current reduction above ~110°C, hard shutdown at 150°C - sustains charging under thermal stress while ensuring safety. |
| Reverse discharge protection | Blocks battery-to-VDD current flow when input is absent - preserves battery charge during system standby or adapter removal. |

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 package, pinout, and core functionality; same 8.40 V regulation, 13 V OVP, and 10% precondition - differs only in factory option coding (A6S vs G6AI). | Same target applications; both qualified for portable media and UMPC use. | Select MCP73213T-G6AI/MF for production traceability matching Microchip's official ordering code; A6S/MF is functionally identical but may reflect older revision or alternate test binning. |
| BQ24075RGTR | Single-cell focused (4.2 V), lacks dual-cell 8.4 V regulation; no factory-set 8.40 V option; requires external resistor network for voltage setting. | Not suitable for 2-cell Li-ion systems without redesign; limited to 1-cell or stacked configurations with added complexity. | Only consider BQ24075RGTR if migrating to single-cell architecture; MCP73213T-G6AI/MF remains required for native 8.40 V dual-cell compliance. |
Compared with MCP73213-A6S/MF, the MCP73213T-G6AI/MF offers identical electrical behavior and qualification - differing only in part marking and traceability. Versus BQ24075RGTR, it provides native dual-cell support, factory-trimmed voltage, and reduced external component count, making it the only drop-in solution for space-constrained 2-cell Li-ion chargers.

FAQ
What is the factory-preset charge voltage for MCP73213T-G6AI/MF?
The MCP73213T-G6AI/MF is factory-trimmed to deliver an exact 8.40 V regulated output voltage with ±0.6% accuracy over –5°C to +55°C. This value is laser-trimmed during production and cannot be adjusted externally - ensuring repeatable, safe charging for dual-cell Li-ion batteries without calibration overhead.
Does MCP73213T-G6AI/MF support automatic recharge, and what is its threshold?
Yes, MCP73213T-G6AI/MF supports automatic recharge at 95% of the regulated charge voltage (i.e., 7.98 V for its 8.40 V setting). When battery voltage drops below this threshold after charge completion, the device initiates a new full CC/CV cycle - eliminating manual intervention in portable devices like media players.
How is fast charge current programmed on MCP73213T-G6AI/MF?
Fast charge current on MCP73213T-G6AI/MF is set using a single resistor (RPROG) from the PROG pin to VSS. For example, a 1.10 kΩ resistor yields ~1000 mA, while a 10 kΩ resistor sets ~130 mA. The relationship follows IREG = 1104 / RPROG (mA, with RPROG in kΩ), and the device validates this range across temperature.
What protection features does MCP73213T-G6AI/MF include beyond OVP and UVLO?
In addition to 13 V input overvoltage protection and 4.15 V undervoltage lockout, MCP73213T-G6AI/MF integrates thermal regulation (current foldback above ~110°C), thermal shutdown (150°C), battery short protection (25 mA recovery current at <3.4 V), reverse discharge blocking, and elapsed/timeout safety timers - all implemented without external components.
Can MCP73213T-G6AI/MF operate without an external microcontroller?
Yes, MCP73213T-G6AI/MF is designed for fully autonomous operation: it executes complete CC/CV charging, preconditioning, termination, and automatic recharge using only passive components (RPROG, CIN, COUT). The STAT pin provides visual status via LED or host MCU polling - no firmware or digital interface required.
