Product details
Overview
MCP73213-B6AI/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 8.20V regulated output voltage with ±0.6% accuracy across –5°C to +55°C, supports 130–1100 mA resistor-programmable fast charge current, and operates from –40°C to +85°C ambient. It is used in ultra-mobile PCs, portable media players, and walkie-talkies requiring compact, cost-sensitive charging solutions.
For engineers reviewing the MCP73213-B6AI/MF datasheet, MCP73213-B6AI/MF pinout, MCP73213-B6AI/MF application, or MCP73213-B6AI/MF equivalent, this page provides verified technical context, factory-preset configuration details (8.20V VREG, 10% preconditioning, 6 hr elapse timer, 10% end-of-charge threshold, 95% recharge threshold, Type 1 status output), package mapping to DFN-10 (3 mm × 3 mm), and validated alternative options for dual-cell Li-ion charging designs.
Technical Context
The MCP73213-B6AI/MF implements a three-phase linear charge algorithm-preconditioning (10% of IREG), constant-current fast charge, and constant-voltage regulation-with factory-preset 8.20V output and automatic end-of-charge termination at 10% IREG. Its integrated P-channel MOSFET (RDS(ON) = 350 mΩ) enables direct battery connection without external power switches.
Input protection includes 4.15V UVLO with 100 mV hysteresis and 13V OVP with 150 mV hysteresis; thermal regulation begins before 150°C die shutdown, and battery short protection activates below 3.4V with 25 mA recovery current. The PROG pin serves dual function: programming fast charge current via 1–22 kΩ resistor and enabling/disabling charge via high-impedance (>200 kΩ) entry into standby mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-cell Li-ion linear charging applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP73213-A6S/MF | Factory-preset 8.40V output voltage; identical pinout, timing, and protection features | Designed for 8.4V nominal 2-cell Li-ion packs (e.g., standard 8.4V rated batteries) | Select when battery specification requires 8.40V termination instead of 8.20V - no layout or firmware changes needed |
| BQ24075RGTR | Single-cell focused (4.2V max); lacks dual-cell voltage options, preconditioning, and 13V OVP | Targeted at smartphones/tablets with single Li-ion cell and host-controlled charging | Only suitable if redesigning for single-cell architecture and adding external OVP - not drop-in compatible |
Compared with MCP73213-A6S/MF, the MCP73213-B6AI/MF provides lower termination voltage optimized for legacy or high-safety-margin 2-cell packs; compared with BQ24075RGTR, it offers native dual-cell support, integrated OVP, and autonomous operation - making it superior for standalone, cost-sensitive, space-limited applications.

FAQ
What is the factory-preset charge voltage for MCP73213-B6AI/MF?
The MCP73213-B6AI/MF is factory-preset to 8.20V regulated output voltage with ±0.6% accuracy over –5°C to +55°C. This value is laser-trimmed during manufacturing and cannot be adjusted externally. It is optimized for dual-cell Li-ion batteries requiring conservative termination voltage to maximize cycle life and safety margin. The MCP73213-B6AI/MF does not support user-programmable voltage selection - only factory variants differ in VREG.
How does the MCP73213-B6AI/MF handle deeply discharged batteries?
The MCP73213-B6AI/MF enters preconditioning mode when VBAT falls below 71.5% of its 8.20V regulation voltage (i.e., ≤5.873V). In this mode, it delivers 10% of the programmed fast charge current to safely recover cells without lithium plating. A 32-minute internal timer prevents indefinite trickle charging. If the threshold isn't reached within that time, the device signals a fault and halts charging until power cycle or battery removal. This behavior is fixed per the B6AI/MF variant.
What protection features are integrated into the MCP73213-B6AI/MF?
The MCP73213-B6AI/MF integrates input overvoltage protection (13V), undervoltage lockout (4.15V), thermal regulation (active current limiting), thermal shutdown (150°C), battery short protection (3.4V threshold), and reverse discharge prevention. All protections operate autonomously without external components. The 13V OVP and 4.15V UVLO thresholds include hysteresis (150 mV and 100 mV respectively) to prevent oscillation during marginal input conditions. These features are inherent to the MCP73213-B6AI/MF silicon design.
Can the MCP73213-B6AI/MF be used without a microcontroller?
Yes - the MCP73213-B6AI/MF is designed for fully autonomous, stand-alone operation. Its Type 1 status output (On/Off) drives an LED directly; preconditioning, fast charge, CV regulation, end-of-charge, and automatic recharge (at 95% VREG) all execute without host intervention. The PROG pin enables/disables charging via resistor or high-impedance signal, eliminating need for digital control lines. This makes MCP73213-B6AI/MF ideal for cost-sensitive, MCU-less portable devices like camcorders and walkie-talkies.
What is the maximum continuous charge current supported by MCP73213-B6AI/MF?
The MCP73213-B6AI/MF supports a maximum continuous fast charge current of 1100 mA, set by a 1.0 kΩ resistor from PROG to VSS. This rating assumes proper thermal design: DFN-10 package with exposed pad soldered to ≥1 cm² copper area and ≥4 thermal vias. At 1100 mA and 12V input to 8.2V battery, power dissipation exceeds 4W - requiring derating or airflow in enclosed environments. The device's thermal regulation automatically reduces current if die temperature approaches 150°C, ensuring reliability without external thermal monitoring.
