Product details
Overview
MCP73213T-A6AI/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 8.40 V regulated charge voltage, supports 130–1100 mA resistor-programmable fast charge current, and operates across –40°C to +85°C for portable media players and ultra-mobile PCs.
For engineers reviewing the MCP73213T-A6AI/MF datasheet, MCP73213T-A6AI/MF pinout, MCP73213T-A6AI/MF application, or MCP73213T-A6AI/MF equivalent, this page provides verified technical context, factory-preset configuration details (8.40 V, 10% preconditioning, 32-min timer, 6-hr elapse safety timer, 10% end-of-charge threshold, 95% automatic recharge, Type 1 status output), and real-world design implications for space-constrained, cost-sensitive charging systems.
Technical Context
The MCP73213T-A6AI/MF implements a three-phase linear charge algorithm-preconditioning (10% of IREG), constant-current fast charge (programmed via RPROG), and constant-voltage regulation at 8.40 V-with integrated thermal regulation that dynamically reduces charge current above ~110°C to maintain reliability. Its internal 350 mΩ P-channel MOSFET pass device enables direct battery connection without external FETs.
Input protection includes 4.15 V UVLO with 100 mV hysteresis and 13 V OVP with 150 mV hysteresis; battery short protection activates below 3.4 V with 25 mA recovery current. The STAT pin provides open-drain status signaling (Type 1: on/off) synchronized to charge state transitions, while PROG serves dual role as current-set input and enable control (200 kΩ impedance triggers standby).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 8.40 V ±0.6% over –5°C to +55°C - ensures precise dual-cell Li-ion termination without overvoltage stress. |
| Fast Charge Current | 130–1100 mA set by single RPROG (1–22 kΩ) - enables flexible current scaling for 500–1100 mAh batteries. |
| Input OVP Threshold | 13.0 V ±0.2 V - protects against wall-adapter spikes and allows use in unregulated 12 V supply environments. |
| Thermal Regulation | Active current limiting above ~110°C - maintains safe die temperature during high-power dissipation in DFN-10 package. |
| Preconditioning | Enabled at 71.5% of VREG (6.01 V), 10% IREG - safely recovers deeply depleted 2-cell packs before full-rate charging. |
| End-of-Charge Control | 10% IREG minimum current ratio - balances full capacity utilization with minimal overcharge risk in CV phase. |
| Automatic Recharge | Triggers at 95% of VREG (7.98 V) - restores charge after self-discharge without host intervention. |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - supports compact PCB layout and 62°C/W junction-to-ambient thermal resistance. |
Pinout & Package
DFN-10 (3 mm × 3 mm) package with exposed thermal pad (EP) for enhanced heat dissipation. Pin 1 marked by dot; pins 1/2 = VDD, 3/4 = VBAT, 5/6 = NC, 7 = STAT, 8/9 = VSS, 10 = PROG, 11 = EP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2) | Battery management input supply | Accepts 4.2–13 V input; 18 V absolute max; internal UVLO/OVP monitoring; bypass with ≥1 μF capacitor. |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to 2-cell Li-ion (+) terminal; requires ≥1 μF output capacitor. |

Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | 350 mΩ RDS(on) P-MOSFET eliminates need for external power switch and simplifies BOM. |
| Factory preset configuration | 8.40 V charge voltage, 10% preconditioning, 32-min precondition timer, 6-hr elapse safety timer, 10% ITERM, 95% VRTH, Type 1 STAT - reduces design validation effort for standard 2-cell applications. |

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 factory preset (8.40 V, 10% precondition, 32-min timer, 6-hr elapse, 10% ITERM, 95% VRTH, Type 1 STAT) but in SOIC-8 package. | Larger footprint, higher θJA (120°C/W), no exposed pad - suitable where thermal constraints are less severe and through-hole or larger surface-mount assembly is preferred. | Select MCP73213-A6S/MF only if DFN-10 assembly capability is unavailable or board-level thermal management cannot accommodate DFN package. |
| BQ24075RGTR | Single-cell 4.2 V fixed output; no factory-programmed multi-cell options; 1000 mA max ICHG; different pinout and status signaling (TS/CE/PG). | Requires external voltage divider or second-stage regulation for 2-cell stacks; lacks integrated OVP and preconditioning - not drop-in compatible. | Choose BQ24075RGTR only for single-cell designs or when TI's ecosystem (e.g., bqStudio, companion fuel gauges) is already established. |
Compared with MCP73213-A6S/MF, the MCP73213T-A6AI/MF offers superior thermal performance (62 vs. 120°C/W) and 30% smaller footprint, enabling thinner portable devices; versus BQ24075RGTR, it delivers native dual-cell support, integrated 13 V OVP, and factory-configured safety thresholds - eliminating design-time configuration decisions and validation overhead.

FAQ
What is the factory-programmed charge voltage for MCP73213T-A6AI/MF?
The MCP73213T-A6AI/MF is factory preset to 8.40 V ±0.6% over –5°C to +55°C, optimized for dual-cell Li-ion/Li-polymer battery termination. This value is laser-trimmed during manufacturing and cannot be adjusted externally - ensuring consistent, repeatable performance across production lots without calibration.
How does the MCP73213T-A6AI/MF handle deeply discharged batteries?
The MCP73213T-A6AI/MF enters preconditioning mode when VBAT falls below 71.5% of its 8.40 V regulation voltage (i.e., 6.01 V), supplying 10% of the programmed fast charge current to safely recover the cell. This prevents lithium plating and enables controlled reactivation before full-rate charging resumes - a critical safety feature for field-deployed devices.
What thermal management features does MCP73213T-A6AI/MF include?
The MCP73213T-A6AI/MF incorporates two-tier thermal protection: first, dynamic current regulation above ~110°C to extend usable charge time; second, hard thermal shutdown at 150°C with 10°C hysteresis. Its DFN-10 package with exposed pad achieves 62°C/W θJA on a 4-layer board, enabling 500 mA continuous charge without external heatsinking in typical portable layouts.
Can MCP73213T-A6AI/MF operate with unregulated wall adapters?
Yes - the MCP73213T-A6AI/MF includes integrated 13 V input overvoltage protection with 150 mV hysteresis, allowing direct connection to low-cost 12 V wall adapters subject to plug/unplug transients. Its 18 V absolute maximum rating on VDD further safeguards against voltage spikes, eliminating need for external TVS or clamping circuits in cost-sensitive designs.
What is the function of the PROG pin on MCP73213T-A6AI/MF beyond setting charge current?
In addition to programming fast charge current via resistor-to-VSS, the PROG pin serves as an enable input: applying >200 kΩ impedance places MCP73213T-A6AI/MF into standby mode with <150 μA quiescent current, while removing the high-Z condition resumes charging. This dual functionality enables simple hardware-based charge control without additional logic or microcontroller intervention.
