Product details
Overview
MCP73213-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, 10% end-of-charge current ratio, and 95% automatic recharge threshold - optimized for portable media players and ultra-mobile PCs.
For engineers reviewing the MCP73213-G6AI/MF datasheet, MCP73213-G6AI/MF pinout, MCP73213-G6AI/MF application, or MCP73213-G6AI/MF equivalent, this page provides verified functional specifications, validated DFN-10 package mapping, confirmed pin roles per Microchip DS20002190D, and two production-validated alternative parts for dual-cell Li-ion charging systems requiring ±0.6% voltage regulation across –5°C to +55°C.
Technical Context
The MCP73213-G6AI/MF implements a three-phase linear charge algorithm: preconditioning (10% of fast charge current), constant-current fast charge (programmable 130–1100 mA via PROG resistor), and constant-voltage regulation (8.40 V ±0.6%). It integrates input overvoltage lockout at 13 V with 150 mV hysteresis and undervoltage lockout at 4.15 V.
Thermal regulation dynamically reduces charge current above die temperature thresholds, while thermal shutdown suspends charging at 150°C with 10°C hysteresis. The STAT pin provides open-drain status signaling with Type 1 (On/Off) output behavior, and PROG serves dual function as current-set input and enable control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 8.40 V ±0.6% over –5°C to +55°C - ensures safe full-charge termination for 2-cell Li-ion without overvoltage stress |
| Input OVP Threshold | 13.0 V ±0.2 V - protects against wall-adapter spikes and enables use in cost-sensitive AC-DC environments |
| Fast Charge Current Range | 130–1100 mA set by single PROG resistor - supports flexible design for 500–1200 mAh battery packs |
| Preconditioning | Enabled at 71.5% of VREG (6.01 V) with 10% IREG - safely recovers deeply depleted cells before fast charge |
| End-of-Charge Termination | 10% IREG minimum current ratio - balances charge completion accuracy and battery longevity |
| Automatic Recharge Threshold | 95% of VREG (7.98 V) - triggers top-up charge when battery self-discharge drops voltage below safe operating level |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - enables compact PCB layout and 62°C/W junction-to-ambient thermal resistance |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP); EP must be soldered to PCB copper for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2) | Battery management input supply | Accepts 4.2–13 V input; 18 V absolute max; bypass with ≥1 μF capacitor; powers internal circuitry and gate drive |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-channel MOSFET; connects directly to positive terminal of 2-cell Li-ion pack; requires ≥1 μF output capacitor |
| NC (Pins 5, 6) | No connection | Unbonded pins; must remain unconnected on PCB |

FAQ
What is the factory-preset charge voltage for MCP73213-G6AI/MF?
The MCP73213-G6AI/MF is factory configured for 8.40 V regulated charge voltage with ±0.6% tolerance over –5°C to +55°C, as specified in Microchip DS20002190D Table 2. This value is laser-trimmed and non-adjustable, ensuring consistent dual-cell Li-ion termination without external feedback components.
Does MCP73213-G6AI/MF support preconditioning, and what are its settings?
Yes, MCP73213-G6AI/MF supports preconditioning at 10% of the fast charge current, triggered when battery voltage falls below 71.5% of VREG (6.01 V). Its precondition timer is factory set to 32 minutes, and both features are enabled by default per DS20002190D Table 2 - no external configuration required.
What is the input overvoltage protection threshold for MCP73213-G6AI/MF?
The MCP73213-G6AI/MF incorporates integrated input overvoltage protection with a nominal threshold of 13.0 V and ±0.2 V tolerance, plus 150 mV hysteresis. This allows safe operation with low-cost AC-DC adapters and protects against transient spikes up to 18 V absolute maximum rating.
How does the STAT pin behave on MCP73213-G6AI/MF during charging?
The STAT pin on MCP73213-G6AI/MF operates in Type 1 mode (On/Off): it pulls low during preconditioning, fast charge, and constant-voltage phases, and goes high-impedance upon charge completion or fault conditions - enabling direct LED drive or microcontroller GPIO monitoring without external pull-up.
What package type and thermal requirements apply to MCP73213-G6AI/MF?
MCP73213-G6AI/MF uses a 10-lead DFN package (3 mm × 3 mm) with exposed thermal pad (EP). The EP must be soldered to a PCB copper plane with ≥4 thermal vias to achieve 62°C/W θJA; failure to connect EP degrades thermal regulation performance and may trigger premature current limiting.
