Product details
Overview
MCP73213T-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 MCP73213T-A6X/MF datasheet, MCP73213T-A6X/MF pinout, MCP73213T-A6X/MF application, or MCP73213T-A6X/MF equivalent, this page provides verified technical context, factory-preset configuration details (8.40 V, 10% preconditioning, 32-min timer, 6-hr elapse safety timer, 10% end-of-charge threshold, 95% automatic recharge, Type 1 status output), and real-world design implications for space-constrained, cost-sensitive charging systems.
Technical Context
The MCP73213T-A6X/MF implements a three-phase linear charge algorithm-preconditioning (10% of IREG), constant-current fast charge, then constant-voltage regulation at 8.40 V-with integrated thermal regulation that dynamically reduces charge current above ~110°C to prevent die overheating. Its internal P-channel MOSFET (RDS(ON) = 350 mΩ) enables direct battery connection without external power switches.
Input protection includes 4.15 V UVLO with 100 mV hysteresis and 13 V OVP with 150 mV hysteresis; battery short protection activates below 3.4 V with 25 mA recovery current. The PROG pin serves dual roles: programming fast charge current via 1–22 kΩ resistor and enabling/disabling charge via high-impedance (>200 kΩ) shutdown 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-capacity charging of 2-cell Li-ion packs without overvoltage stress. |
| Fast Charge Current | 130–1100 mA set by single PROG-to-VSS resistor - enables precise current tuning for battery capacity and thermal budget. |
| Input OVP Threshold | 13.0 V ±0.2 V - protects against voltage spikes from low-cost wall adapters or plug/unplug transients. |
| UVLO Threshold | 4.15 V ±0.05 V with 100 mV hysteresis - prevents operation during insufficient input supply while avoiding chatter near cutoff. |
| Thermal Regulation | Active current limiting above ~110°C - maintains reliability under high ambient or high-power conditions without external thermal sensors. |
| End-of-Charge Termination | 10% of fast charge current - balances full charge completion against excessive time in CV phase for cycle life preservation. |
| Automatic Recharge Threshold | 95% of VREG (i.e., 7.98 V) - triggers top-up charge before battery self-discharge depletes usable capacity. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) for enhanced heat dissipation in compact layouts.
| 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-MOSFET; connects directly to 2-cell battery positive; requires ≥1 μF output capacitance for stability. |
| NC (Pins 5, 6) | No connection | Unbonded pins; must remain floating - no routing or copper fill required. |
| STAT (Pin 7) | Status output | Open-drain indicator: LOW during active charge, HIGH-Z at completion or fault; drives LED or microcontroller GPIO. |
| VSS (Pins 8, 9) | 0 V reference | Common ground return for battery negative, input supply negative, and all internal circuits - must be low-impedance. |
| PROG (Pin 10) | Current regulation & enable | Resistor sets fast charge current; >200 kΩ impedance disables charge and enters standby mode. |
| EP (Pin 11) | Exposed thermal pad | Must be soldered to PCB copper pour with multiple thermal vias - critical for thermal regulation performance and reliability. |
Key Features
| Feature | Design Value |

| Integrated pass transistor | Eliminates need for external MOSFET and gate driver - reduces BOM count and layout area in portable designs. |
| Factory-preset 8.40 V regulation | Guarantees accurate dual-cell Li-ion termination without external feedback resistors - simplifies compliance with battery manufacturer specs. |
| Preconditioning with 10% ratio | Safely recovers deeply depleted cells below 66.5% of VREG (i.e., ~5.63 V) before fast charge - prevents lithium plating. |
| 32-minute precondition timer | Prevents indefinite trickle charging if cell fails to reach threshold - avoids thermal runaway risk in faulty batteries. |
| Type 1 status output (On/Off) | Provides unambiguous charge state signaling without flashing logic - simplifies LED interface and host MCU polling. |

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, 10% preconditioning, 32-min timer, 6-hr elapse timer, 10% termination, 95% recharge, Type 1 output - same factory preset configuration. | No functional difference; both support identical charge profiles and thermal behavior in DFN-10 package. | Select MCP73213T-A6X/MF for tape-and-reel delivery; MCP73213-A6S/MF for sample quantities or alternate packaging. |
| BQ24075RGTR | Single-cell only (4.2 V), no factory preset voltage option, requires external resistor for VREG, lacks integrated OVP, uses different STAT timing logic. | Not suitable for dual-cell 8.4 V systems; requires redesign of feedback network, protection circuitry, and status interpretation. | Only consider if migrating to single-cell architecture; otherwise, MCP73213T-A6X/MF provides direct dual-cell functionality with no layout changes. |
Compared with MCP73213-A6S/MF, the MCP73213T-A6X/MF offers identical electrical and functional behavior but optimized for automated SMT assembly via tape-and-reel packaging; versus BQ24075RGTR, it delivers native dual-cell support, built-in 13 V OVP, and factory-trimmed 8.40 V regulation - eliminating calibration effort and external protection components.

FAQ
What is the factory-preset charge voltage for MCP73213T-A6X/MF?
The MCP73213T-A6X/MF is factory preset to 8.40 V ±0.6% over –5°C to +55°C, optimized for dual-cell Li-ion/Li-polymer battery termination. This value is laser-trimmed and non-adjustable, ensuring consistent performance without external feedback components. The MCP73213T-A6X/MF achieves this regulation using an internal reference and precision amplifier, maintaining accuracy even under varying load and temperature conditions.
How does the PROG pin function in MCP73213T-A6X/MF?
The PROG pin on the MCP73213T-A6X/MF serves two critical functions: it sets the fast charge current via a resistor to VSS (130–1100 mA range), and acts as an enable/disable control - applying >200 kΩ impedance places the MCP73213T-A6X/MF into standby mode with <5 μA supply current. This dual role eliminates the need for separate enable circuitry and simplifies system-level power sequencing.
Does MCP73213T-A6X/MF include input overvoltage protection?
Yes, the MCP73213T-A6X/MF integrates 13 V input overvoltage protection with 150 mV hysteresis, disabling charge when VDD exceeds 13.2 V and re-enabling only after falling below 12.8 V. This protects downstream circuitry from transient spikes common with low-cost AC-DC adapters and plug/unplug events - a feature not present in many competing linear chargers like the BQ24075RGTR.
What thermal protection mechanisms does MCP73213T-A6X/MF implement?
The MCP73213T-A6X/MF employs two-tier thermal protection: first, continuous thermal regulation that progressively reduces charge current above ~110°C to maintain safe die temperature; second, hard thermal shutdown at 150°C ±10°C that suspends charging until die cools by ~10°C. Both features operate independently of external components and are fully specified across –40°C to +85°C ambient.
What is the purpose of the exposed thermal pad (EP) on MCP73213T-A6X/MF?
The exposed thermal pad (EP) on the MCP73213T-A6X/MF is electrically connected to VSS and thermally coupled to the die - it must be soldered to a PCB copper pour with ≥4 thermal vias to achieve the specified 62°C/W θJA. Without proper EP connection, thermal regulation becomes ineffective and device reliability degrades significantly under sustained 500+ mA charge currents.
