Product details
Overview
MCP73213-A6X/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 output 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-A6X/MF datasheet, MCP73213-A6X/MF pinout, MCP73213-A6X/MF application, or MCP73213-A6X/MF equivalent, this page provides verified functional specifications, DFN-10 package layout, factory-preset 8.40 V charge voltage, 10% preconditioning, 32-minute precondition timer, 6-hour elapse safety timer, and 10% end-of-charge current ratio - all confirmed for the A6X/MF variant.
Technical Context
The MCP73213-A6X/MF implements a three-phase linear charging algorithm: preconditioning (10% of IREG at VBAT < 71.5% × VREG), constant-current fast charge (programmed via RPROG), and constant-voltage regulation (8.40 V ±0.6% over –5°C to +55°C). It integrates thermal regulation to throttle current above ~110°C and suspends charging above 150°C die temperature.
Its input stage includes undervoltage lockout (4.15 V start, 100 mV hysteresis) and overvoltage protection (13 V threshold, 150 mV hysteresis), enabling robust operation with low-cost wall adapters. The PROG pin serves dual roles: fast-charge current programming and enable control - high-impedance (>200 kΩ) forces standby mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | Factory preset 8.40 V ±0.6% over –5°C to +55°C - ensures safe full-charge termination for 2-cell Li-ion packs without external feedback resistors. |
| Input OVP Threshold | 13.0 V ±0.2 V - protects against voltage spikes from unregulated AC-DC adapters and plug/unplug transients. |
| Fast Charge Current | Resistor programmable 130–1100 mA (via 1–10 kΩ RPROG) - enables precise matching to battery capacity and thermal limits. |
| Preconditioning | Enabled at 10% of IREG, triggered below 71.5% × VREG - safely recovers deeply depleted cells before fast charge. |
| End-of-Charge Termination | 10% IREG minimum current ratio - balances charge completeness and battery longevity in constant-voltage phase. |
| Elapse Safety Timer | Factory set to 6 hours - prevents indefinite charging under fault conditions such as open thermistor or failed battery. |
| Operating Temperature | –40°C to +85°C ambient - validated for use in handheld devices exposed to wide environmental ranges. |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - supports compact PCB layouts and efficient heat dissipation in space-constrained designs. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP), optimized for thermal performance in portable applications.
| 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 (4.15 V) and OVP (13 V) protect system during adapter transients. |
| VBAT (Pins 3, 4) | Battery charge control output | Drives positive terminal of 2-cell Li-ion pack; integrates P-channel MOSFET with 350 mΩ typical RDS(on) at 105°C. |
| NC (Pins 5, 6) | No connection | Unbonded pins - must remain floating; no routing or copper fill required beneath. |
| STAT (Pin 7) | Status output | Open-drain indicator: low during active charge, high-Z at completion; supports LED drive or microcontroller polling. |
| VSS (Pins 8, 9) | Ground reference | Common return for battery negative, input supply, and internal circuitry - requires low-impedance PCB plane connection. |
| PROG (Pin 10) | Current regulation & enable | Connects to VSS via RPROG to set fast charge current; >200 kΩ impedance disables charging and enters standby. |
| EP (Pin 11) | Exposed thermal pad | Must be soldered to PCB copper pour with ≥4 thermal vias - reduces θJA to 62°C/W for stable thermal regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | On-chip P-MOSFET eliminates external switch and simplifies BOM - reduces solution size and layout complexity for dual-cell chargers. |
| Input overvoltage protection | 13 V clamping with 150 mV hysteresis - enables direct use with low-cost, unregulated wall warts without external TVS diodes. |
| Thermal regulation | Dynamic current reduction above ~110°C junction - maintains safe operation during high-power charging without external thermal sensors. |
| Factory-preset charge parameters | 8.40 V regulation, 10% preconditioning, 32-min precondition timer, 6-hr elapse timer, 10% termination ratio - eliminates configuration firmware or external logic. |
| Reverse discharge protection | Internal blocking prevents battery self-discharge when input power is removed - extends shelf life in always-connected portable devices. |
| Automatic recharge | Reinitiates charge when VBAT drops to 95% of VREG - maintains full capacity in intermittently used devices like walkie-talkies and 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 | Identical 8.40 V regulation, but uses Type 1 (On/Off) STAT output instead of Type 2 (flashing) - no visual fault indication for thermal/timer faults. | Suitable for cost-sensitive designs where flashing status is not required; same pinout and electrical behavior otherwise. | Select MCP73213-A6S/MF only if flashing fault indication is unnecessary and BOM cost reduction is prioritized. |
| BQ24075RGTR | TI part with 8.4 V output, but lacks integrated OVP (requires external 13 V TVS), no preconditioning, and uses different STAT timing logic (active-low vs open-drain). | Requires additional protection components and external preconditioning circuitry - increases design complexity and footprint. | Choose BQ24075RGTR only if existing TI ecosystem integration outweighs added component count and reduced safety features. |
Compared with MCP73213-A6X/MF, MCP73213-A6S/MF offers identical charging functionality but omits flashing fault indicators, while BQ24075RGTR demands external OVP and lacks preconditioning - making MCP73213-A6X/MF the most integrated, drop-in-ready solution for space- and safety-critical dual-cell applications.

FAQ
What is the factory-preset charge voltage for MCP73213-A6X/MF?
The MCP73213-A6X/MF is factory configured for 8.40 V constant-voltage regulation, with ±0.6% accuracy over –5°C to +55°C. This value is laser-trimmed during manufacturing and cannot be adjusted externally - ensuring consistent, safe termination for 2-cell Li-ion batteries without calibration.
How does the MCP73213-A6X/MF handle overvoltage conditions on the VDD input?
The MCP73213-A6X/MF incorporates an internal overvoltage protection circuit that disables charging when VDD exceeds 13.0 V (±0.2 V), with 150 mV hysteresis. During OVP, the device enters shutdown mode, sets STAT to high-impedance, and suspends all charge activity - protecting both the IC and battery from damage due to adapter spikes or miswiring.
What is the function of the PROG pin on the MCP73213-A6X/MF beyond setting charge current?
In addition to programming fast-charge current via RPROG, the PROG pin on MCP73213-A6X/MF serves as an enable input: applying >200 kΩ impedance places the device in standby mode with <150 μA quiescent current, while connecting RPROG to VSS resumes normal operation - enabling simple hardware-based charge control without a microcontroller.
Does the MCP73213-A6X/MF support automatic recharge, and at what threshold?
Yes, the MCP73213-A6X/MF supports automatic recharge at 95% of its regulated voltage (i.e., 7.98 V for the 8.40 V variant). When VBAT drops below this threshold in Charge Complete mode, the device automatically restarts the full CC/CV cycle - ideal for devices like walkie-talkies that require persistent readiness without manual intervention.
What thermal protection mechanisms are implemented in the MCP73213-A6X/MF?
The MCP73213-A6X/MF features two-tier thermal protection: first, continuous thermal regulation that progressively reduces charge current above ~110°C junction temperature; second, hard thermal shutdown at 150°C (±5°C), which halts charging until die temperature falls by ~10°C. Both functions are fully integrated and require no external components.
