Product details
Overview
MCP73213T-F6TI/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 constant-current/constant-voltage charging with factory-preset 8.40V output voltage, ±0.6% regulation accuracy across –5°C to +55°C, and resistor-programmable fast charge current up to 1100 mA. It is used in ultra-mobile PCs, portable media players, and walkie-talkies where space-constrained, cost-sensitive, single-chip charging is required.
For engineers reviewing the MCP73213T-F6TI/MF datasheet, MCP73213T-F6TI/MF pinout, MCP73213T-F6TI/MF application, or MCP73213T-F6TI/MF equivalent, key selection considerations include its DFN-10 (3×3 mm) package, 8.40V fixed charge voltage, 13V input OVP threshold, 4.15V UVLO, and automatic recharge at 95% VREG - all confirmed for this exact variant per Microchip DS20002190D.
Technical Context
The MCP73213T-F6TI/MF implements a full linear CC/CV charge algorithm optimized for 2-cell Li-ion packs, with factory-trimmed 8.40V regulation and integrated thermal foldback that dynamically reduces charge current above ~110°C to prevent die overheating. Its PROG pin serves dual function: setting fast charge current via external resistor (130–1100 mA range) and enabling/disabling charge via high-impedance detection (≥200 kΩ triggers standby).
It features comprehensive safety logic including 32-minute precondition timer, elapse safety timer (6 hr), end-of-charge termination at 10% IREG, automatic recharge at 95% VREG, and battery short protection with 25 mA recovery current. All thresholds - UVLO (4.15V), OVP (13V), VPTH/VREG (71.5%), and VRTH/VREG (95%) - are factory preset and verified for this specific part number.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 8.40V ±0.6% over –5°C to +55°C - ensures precise dual-cell Li-ion termination without external feedback components. |
| Input OVP Threshold | 13.0V ±0.2V - protects against wall-adapter spikes and enables use with low-cost AC-DC supplies up to 18V abs max. |
| UVLO Threshold | 4.15V start / 4.05V stop - prevents operation below safe input range while providing 100 mV hysteresis for stable enable/disable. |
| Fast Charge Current Range | 130–1100 mA set by single PROG-to-VSS resistor - supports flexible design for 500–1200 mAh battery capacities. |
| Thermal Regulation | Active foldback starting ~110°C - maintains reliability under high ambient or high-power dissipation without external thermal sensors. |
| Preconditioning | Enabled at 71.5% VREG (6.01V), 10% IREG current, 32-minute timer - safely recovers deeply depleted 2-cell packs before fast charge. |
| End-of-Charge Termination | 10% IREG current ratio with 1 ms filter - avoids false termination during transient load events on battery line. |
| Automatic Recharge | Enabled at 95% VREG (7.98V) - restores full capacity after self-discharge without host intervention. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP); RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2) | Battery management input supply | Accepts 4.2–13V input; 18V absolute max; internal UVLO/OVP monitoring; bypass with ≥1 μF to VSS. |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to 2-cell Li-ion (+) terminal; regulates voltage to 8.40V. |
| NC (Pins 5, 6) | No connection | Unbonded pins; must remain floating - no routing or soldering required. |

| VSS (Pins 8, 9) | 0V reference | Common ground for battery negative, input supply return, and all internal circuitry; connect to EP for thermal path. |
| PROG (Pin 10) | Current regulation & enable | Resistor sets fast charge current (130–1100 mA); ≥200 kΩ impedance disables charge and enters standby. |
| EP (Pin 11) | Exposed thermal pad | Internally connected to VSS; must be soldered to PCB copper pour with ≥4 thermal vias for thermal regulation compliance. |
Key Features
| Feature | Design Value |

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 8.40V VREG, same OVP (13V), precondition (10%), timer (32 min/6 hr), ITERM (10%), VRTH (95%), and Type 1 status - differs only in tape-and-reel packaging (MF vs TI/MF). | Same functional behavior; MF variant uses standard reel packaging, while TI/MF denotes tray + tape option - no electrical or thermal difference. | Select MCP73213T-F6TI/MF for tray + tape delivery; choose MCP73213-A6S/MF for standard reel if volume procurement favors automated placement. |
| BQ24075RGTR | Single-cell focused (4.2V), no factory-set 8.4V option; requires external resistor for VREG; lacks integrated 13V OVP - needs external TVS; different pinout and thermal pad layout. | Designed for 1-cell systems; unsuitable for direct 2-cell replacement without redesign of voltage sensing, OVP, and thermal layout. | Only consider BQ24075RGTR if migrating to single-cell architecture; MCP73213T-F6TI/MF remains optimal for space-constrained 2-cell Li-ion applications requiring integrated OVP and factory-trimmed voltage. |
Compared with MCP73213-A6S/MF, the MCP73213T-F6TI/MF offers identical electrical performance but with tray + tape packaging for mixed-SMT lines; versus BQ24075RGTR, it provides native 2-cell support, integrated 13V OVP, and zero-config 8.40V regulation - reducing validation effort and PCB area by >30%.

FAQ
What is the factory-preset charge voltage for MCP73213T-F6TI/MF?
The MCP73213T-F6TI/MF is factory configured for 8.40V constant-voltage regulation, with ±0.6% accuracy over –5°C to +55°C ambient temperature. This value is laser-trimmed and non-adjustable - no external resistors or programming are needed to achieve precise dual-cell Li-ion termination. The 8.40V setting matches common 2S Li-ion pack requirements and is confirmed in Table 2 of Microchip DS20002190D.
Does MCP73213T-F6TI/MF support automatic recharge, and at what threshold?
Yes, MCP73213T-F6TI/MF supports automatic recharge at 95% of its regulated voltage - i.e., 7.98V for the 8.40V variant. When battery voltage drops below this threshold in Charge Complete mode, the device automatically restarts the full CC/CV cycle. This behavior is factory enabled and does not require external components or host control, making it ideal for maintenance-free portable devices.
What is the input overvoltage protection threshold for MCP73213T-F6TI/MF?
The MCP73213T-F6TI/MF features integrated input overvoltage protection with a nominal threshold of 13.0V, ±0.2V tolerance, and 150 mV hysteresis. When VDD exceeds this level, the device shuts down charging and places STAT in HIGH-Z state. This allows safe operation with low-cost wall adapters and suppresses damage from plug/unplug spikes - a key differentiator versus chargers requiring external OVP circuitry.
How is fast charge current programmed on MCP73213T-F6TI/MF?
Fast charge current on MCP73213T-F6TI/MF is set using a single resistor (RPROG) from PROG pin to VSS, supporting 130–1100 mA range. For example, a 2.00 kΩ resistor yields ~550 mA (per Equation 5-1 in DS20002190D). The PROG pin also serves as enable: applying ≥200 kΩ impedance places MCP73213T-F6TI/MF in standby mode, reducing quiescent current to <150 μA.
What package type and thermal characteristics does MCP73213T-F6TI/MF use?
MCP73213T-F6TI/MF uses a 10-lead DFN package (3 mm × 3 mm) with exposed thermal pad (EP), rated at θJA = 62°C/W on a 4-layer JEDEC board. The EP must be soldered to PCB copper with ≥4 thermal vias to ensure effective heat dissipation. At 500 mA charge current and 9V input, typical power dissipation is ~2.5W - requiring this thermal design to maintain die temperature within safe limits during continuous operation.
