Product details
Overview
MCP73213-A6BI/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, 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 MCP73213-A6BI/MF datasheet, MCP73213-A6BI/MF pinout, MCP73213-A6BI/MF application, or MCP73213-A6BI/MF equivalent, this page provides verified technical context, exact pin functions, real-world use cases, and validated alternative options for dual-cell Li-ion charging designs requiring compact footprint, input surge tolerance, and automatic recharge control.
Technical Context
The MCP73213-A6BI/MF implements a three-phase linear charge algorithm: preconditioning (10% of IREG, 32 min timer), constant-current fast charge (programmed via RPROG), then constant-voltage regulation at 8.40 V ±0.6% over –5°C to +55°C. It integrates input overvoltage lockout at 13 V (150 mV hysteresis) and undervoltage lockout at 4.15 V (100 mV hysteresis).
Thermal regulation dynamically reduces charge current above ~110°C die temperature, while thermal shutdown suspends charging at 150°C (10°C hysteresis). The PROG pin serves dual roles: programming fast-charge current and enabling/disabling charge via impedance detection (>200 kΩ triggers standby mode).
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 external feedback. |
| Input OVP Threshold | 13.0 V ±0.2 V - protects against wall-adapter spikes and enables robust operation in cost-sensitive AC-DC environments. |
| Fast Charge Current Range | 130–1100 mA via single RPROG (1.0–10 kΩ) - simplifies design while supporting 500–875 mAh battery packs. |
| Preconditioning | Enabled at 71.5% VREG (6.0 V), 10% IREG, 32-minute timer - safely recovers deeply depleted 2S batteries before CC mode. |
| End-of-Charge Termination | 10% IREG minimum current ratio - balances full capacity recovery with cycle life for consumer Li-ion cells. |
| Automatic Recharge | Enabled at 95% VREG (8.0 V) - maintains battery readiness in always-on portable devices without host intervention. |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - enables high-power dissipation in space-constrained PCB layouts. |
Pinout & Package
DFN-10 (3 mm × 3 mm) package with exposed thermal pad (EP) for enhanced heat dissipation. Pin 1 marked by dot; EP must be soldered to PCB copper pour with multiple thermal vias.
| 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 active; bypass with ≥1 μF capacitor. |
| VBAT (Pins 3,4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to 2S battery positive; requires ≥1 μF output capacitance. |
| NC (Pins 5,6) | No connection | Unbonded; must remain floating - no routing or stitching required. |
| STAT (Pin 7) | Status output | Open-drain indicator: low during active charge, high-Z at completion, flashing on fault (Type 2). |
| VSS (Pins 8,9) | 0 V reference | Common ground for battery negative, input supply return, and all internal circuitry. |
| PROG (Pin 10) | Current regulation & enable | Resistor-to-VSS sets IREG; >200 kΩ impedance disables charge and enters standby mode. |
| EP (Pin 11) | Exposed thermal pad | Internally connected to VSS; must be soldered to PCB ground plane with ≥4 thermal vias for θJA = 62°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | 350 mΩ RDS(on) at 105°C - eliminates external MOSFET and reduces BOM count in compact chargers. |
| Factory preset 8.40 V regulation | ±0.6% accuracy over –5°C to +55°C - meets JEITA-compliant dual-cell Li-ion voltage requirements without trimming. |
| Input overvoltage protection | 13 V threshold with 150 mV hysteresis - sustains operation during 12 V adapter plug/unplug transients without latch-up. |
| Automatic recharge at 95% VREG | Enables maintenance charging for always-on handhelds without microcontroller polling or wake-up overhead. |
| Thermal regulation + shutdown | Gradual current reduction above 110°C, hard shutdown at 150°C - prevents thermal runaway under high ambient or poor heatsinking. |
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 | Same 8.40 V VREG, identical OVP/UVLO, but Type 1 (On/Off) STAT output vs. Type 2 (Flashing) in A6BI/MF. | Lacks fault-state visual indication; suitable only where flashing status is not required for user feedback. | Select A6S/MF when LED simplicity is prioritized over diagnostic visibility during thermal/timer faults. |
| BQ24075RGTR | Single-cell focused (4.2 V), no factory-set 8.4 V option; requires external resistors for voltage setting; lacks integrated 13 V OVP. | Requires redesign for dual-cell topology; needs additional overvoltage protection circuitry for 12 V adapter inputs. | Choose only if migrating to single-cell architecture or if external voltage programming and discrete OVP are acceptable trade-offs. |
Compared with MCP73213-A6BI/MF, MCP73213-A6S/MF offers identical core charging functionality but omits flashing fault indication, while BQ24075RGTR demands significant schematic changes to support dual-cell voltage and input surge protection - making A6BI/MF optimal for drop-in 2S Li-ion cradle designs.

FAQ
What is the factory-preset charge voltage for MCP73213-A6BI/MF?
The MCP73213-A6BI/MF has a factory-preset regulated charge voltage of 8.40 V with ±0.6% accuracy over –5°C to +55°C. This value is laser-trimmed during manufacturing and cannot be adjusted externally - it is specifically selected for optimal charging of dual-cell Li-ion or Li-polymer battery packs.
How does the PROG pin function in MCP73213-A6BI/MF?
In MCP73213-A6BI/MF, the PROG pin serves two critical roles: (1) it sets the fast-charge current via an external resistor to VSS (130–1100 mA range), and (2) it acts as an enable/disable control - applying >200 kΩ impedance places the device in standby mode with near-zero quiescent current, while connecting the resistor resumes normal operation.
Does MCP73213-A6BI/MF support automatic recharge, and at what threshold?
Yes, MCP73213-A6BI/MF supports automatic recharge at 95% of its factory-set VREG (i.e., 8.0 V), which is confirmed in Table 2 of DS20002190D. When battery voltage drops below this threshold in Charge Complete mode, the device automatically restarts the full precondition → CC → CV cycle without host intervention.
What is the meaning of "Type 2" status output in MCP73213-A6BI/MF?
"Type 2" refers to the STAT pin behavior in MCP73213-A6BI/MF: it outputs a 1.6-second, 50% duty-cycle flashing signal during thermal fault, timer fault, or precondition timer fault conditions - unlike Type 1 (static high-Z). This provides immediate visual diagnostics for end users or service technicians without requiring MCU polling.
What package type and thermal considerations apply to MCP73213-A6BI/MF?
MCP73213-A6BI/MF uses a 10-lead DFN package (3 mm × 3 mm) with an exposed thermal pad (EP). For reliable operation at full current, EP must be soldered to a PCB ground plane with ≥4 thermal vias; this achieves θJA = 62°C/W, preventing thermal regulation onset below 110°C junction temperature under typical loads.
