Product details
Overview
MCP73213T-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 (13 V), and thermal regulation. It delivers factory-preset 8.20 V charge voltage, 10% preconditioning, 6-hour elapsed safety timer, 10% end-of-charge current ratio, and 95% automatic recharge threshold in a 3 mm × 3 mm DFN-10 package - optimized for ultra-mobile PCs and portable media players.
For engineers reviewing the MCP73213T-B6AI/MF datasheet, MCP73213T-B6AI/MF pinout, MCP73213T-B6AI/MF application, or MCP73213T-B6AI/MF equivalent, this page provides verified technical context, exact pin functions, real-world application mappings, and two validated alternative parts with documented functional differences for space-constrained, cost-sensitive dual-cell charging designs.
Technical Context
The MCP73213T-B6AI/MF implements a full CC/CV charge algorithm with integrated P-channel MOSFET control, enabling direct battery connection without external power switches. Its thermal regulation dynamically reduces fast-charge current above ~110°C to maintain reliability while optimizing cycle time.
It features factory-trimmed 8.20 V ±0.6% regulation across –5°C to +55°C, 4.15 V UVLO with 100 mV hysteresis, and precise 10% preconditioning current ratio relative to IREG, all managed by internal state logic that suspends charging on OVP (13 V), timer expiry, or die temperature >150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 8.20 V ±0.6% over –5°C to +55°C - ensures safe, full capacity charging of 2-cell Li-ion packs without external voltage-setting components. |
| Input OVP Threshold | 13.0 V ±0.2 V - protects against wall-adapter spikes and enables robust operation in low-cost AC-DC environments. |
| Fast Charge Current Range | 130–1100 mA set by single PROG resistor - supports flexible design for 500–1200 mAh battery capacities. |
| Preconditioning | Enabled at 10% of IREG below 71.5% VREG - safely recovers deeply depleted cells before CC mode. |
| End-of-Charge Termination | 10% IREG current ratio with 6-hour elapsed timer - balances charge completeness and cell longevity. |
| Automatic Recharge | Triggered at 95% VREG - maintains battery readiness without host intervention in always-on portable devices. |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - enables compact PCB layout and efficient heat dissipation in thin-profile applications. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) for enhanced thermal performance. Pin 11 (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; 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; requires ≥1 μF bypass for stability. |
| NC (Pins 5,6) | No connection | Unbonded pins; must remain unconnected and unrouted on PCB. |
| STAT (Pin 7) | Status output | Open-drain indicator: LOW during active charge, HIGH-Z at completion, flashing on fault - drives LED or MCU GPIO. |
| VSS (Pins 8,9) | 0 V reference | Common ground for battery negative, input supply return, and all internal bias circuits. |
| PROG (Pin 10) | Current regulation & enable | Resistor-to-VSS sets IREG; >200 kΩ impedance forces standby - eliminates need for external enable logic. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | 350 mΩ RDS(on) at 105°C - eliminates external MOSFET and reduces BOM count in space-limited designs. |
| Input overvoltage protection | 13 V threshold with 150 mV hysteresis - prevents damage from adapter surges without external TVS diodes. |
| Thermal regulation | Dynamic current reduction above ~110°C - sustains safe operation under high ambient or high-power conditions. |
| Factory preset configuration | Fixed 8.20 V VREG, 10% precondition, 6 hr timer, 10% ITERM, 95% VRTH - eliminates configuration resistors and firmware setup. |
| Reverse discharge protection | ≤2 μA leakage at VDD ≤ VBAT - prevents battery drain when input power is removed, extending standby time. |
Applications
| Digital Camcorders | Portable Media Players |
|---|---|

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 | Factory preset to 8.40 V charge voltage, same 13 V OVP, 10% precondition, 6 hr timer, 10% ITERM, 95% VRTH. | Designed for higher-voltage 2-cell Li-ion chemistries requiring 8.4 V nominal full-charge point. | Select when battery specification mandates 8.40 V VREG; otherwise, MCP73213T-B6AI/MF's 8.20 V setting better suits aging or lower-stress cycling. |
| BQ24075RGTR | TI part with 8.4 V fixed VREG, 1.5 A max ICHG, no factory-programmed precondition or timer; requires external resistor for ICHG. | Supports higher current but lacks integrated 10% precondition and 6-hour elapsed timer - needs host MCU or external logic for full safety compliance. | Choose for higher-current (≥1 A) applications where external timing control is acceptable; MCP73213T-B6AI/MF offers tighter integration and lower system-level BOM. |
Compared with MCP73213-A6S/MF, MCP73213T-B6AI/MF provides lower 8.20 V regulation for extended cycle life in cost-sensitive portable devices; versus BQ24075RGTR, it delivers complete autonomous charging with no host dependency or external timing components.

FAQ
What is the factory-preset charge voltage of the MCP73213T-B6AI/MF?
The MCP73213T-B6AI/MF has a factory-preset regulated charge voltage of 8.20 V ±0.6% across –5°C to +55°C. This value is laser-trimmed during manufacturing and cannot be adjusted externally - it is specifically optimized for dual-cell Li-ion batteries requiring conservative full-charge voltage to maximize cycle life and safety.
How does the MCP73213T-B6AI/MF implement input overvoltage protection?
The MCP73213T-B6AI/MF integrates a dedicated input overvoltage protection circuit with a 13.0 V ±0.2 V start threshold and 150 mV hysteresis. When VDD exceeds this threshold, the device immediately disables charging, places STAT in HIGH-Z state, and suspends the internal timer - protecting both itself and the connected battery from damage due to wall-adapter spikes or plug/unplug transients.
What is the function of the PROG pin on the MCP73213T-B6AI/MF?
The PROG pin on the MCP73213T-B6AI/MF serves two critical roles: (1) it sets the fast-charge current (130–1100 mA) via an external resistor to VSS, and (2) it acts as a hardware enable - applying >200 kΩ impedance places the MCP73213T-B6AI/MF into low-power standby mode, eliminating the need for external enable circuitry or firmware control.
Does the MCP73213T-B6AI/MF support automatic recharge, and at what threshold?
Yes, the MCP73213T-B6AI/MF supports automatic recharge triggered when the battery voltage falls to 95% of its regulated charge voltage (i.e., 95% × 8.20 V = 7.79 V). This feature is factory enabled and requires no external components - it allows the device to autonomously restart charging after self-discharge, maintaining battery readiness in always-on portable equipment.
What thermal protection mechanisms are built into the MCP73213T-B6AI/MF?
The MCP73213T-B6AI/MF incorporates two layered thermal protections: (1) thermal regulation - progressively reduces fast-charge current above ~110°C to balance charging speed and reliability, and (2) thermal shutdown - halts all charging if die temperature exceeds 150°C, resuming only after cooling by ~10°C. Both functions operate independently of host control and require no external sensors.
