Product details
Overview
MCP73213-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 (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 in portable media players and ultra-mobile PCs.
For engineers reviewing the MCP73213-F6TI/MF datasheet, MCP73213-F6TI/MF pinout, MCP73213-F6TI/MF application, or MCP73213-F6TI/MF equivalent, this page provides verified technical context, factory-preset configuration details (8.40 V, 10% preconditioning, 6 hr elapse timer, 10% end-of-charge threshold, 95% recharge threshold, Type 1 status output), package mapping, and real-world design implications for space-constrained, cost-sensitive charging systems.
Technical Context
The MCP73213-F6TI/MF implements a three-phase linear charging algorithm-preconditioning (10% of IREG), constant-current fast charge, and constant-voltage regulation-with automatic transition logic and die-temperature-based current limiting. Its internal P-channel MOSFET (RDS(ON) = 350 mΩ @ 105°C) enables direct battery connection without external power switches.
Charge control is managed via PROG pin impedance: 1–10 kΩ sets fast charge current; ≥200 kΩ forces standby mode. Status indication uses open-drain STAT output with Type 1 (on/off) behavior, while UVLO (4.15 V start/4.05 V stop) and OVP (13 V) ensure robust input supply handling up to 18 V absolute maximum.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulated Charge Voltage | 8.40 V ±0.6% over –5°C to +55°C - ensures precise dual-cell Li-ion termination without overvoltage stress |
| Fast Charge Current Range | 130–1100 mA set by single PROG-to-VSS resistor - enables flexible current scaling for 500–1100 mAh battery packs |
| Input Overvoltage Protection | 13.0 V ±0.2 V threshold - protects against wall-adapter spikes and unregulated DC sources |
| Undervoltage Lockout | 4.15 V start / 4.05 V stop with 100 mV hysteresis - prevents operation below safe input range and avoids brownout oscillation |
| Thermal Regulation | Active current limiting above junction temperature - maintains reliability during high-power dissipation in DFN-10 package |
| Preconditioning Threshold | 71.5% of VREG (6.01 V) - initiates trickle charge for deeply depleted 2-cell batteries before fast charge |
| End-of-Charge Termination | 10% of fast charge current - balances full capacity recovery with cycle life preservation |
| Recharge Threshold | 95% of VREG (7.98 V) - triggers automatic top-up when battery self-discharge drops voltage post-termination |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) - optimized for compact portable layouts and thermal performance on 4-layer PCBs (θJA = 62°C/W).
| 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 Li-ion (+) terminal; requires ≥1 μF output capacitance |
| NC (Pins 5, 6) | No connection | Unbonded pins - must remain floating; no routing or copper fill required |
| STAT (Pin 7) | Status output | Open-drain logic output (Type 1: on/off); sinks up to 35 mA; drives LED or microcontroller GPIO |
| VSS (Pins 8, 9) | 0 V reference | Common ground return for battery negative, input supply, and all internal circuits - must be low-impedance star point |
| PROG (Pin 10) | Current regulation & enable | Sets fast charge current via resistor to VSS; ≥200 kΩ impedance disables charging 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 effective heat dissipation |
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 pinout and package; same 8.40 V regulation but different factory preset timing/status options (e.g., 6 hr elapse timer, Type 1 output) | Same target applications; differs only in preconfigured safety timers and status behavior | Select MCP73213-A6S/MF if exact match to A6S configuration is required; MCP73213-F6TI/MF is functionally identical for 8.40 V systems with 6 hr timer and Type 1 STAT. |
| BQ24075RGTR | Single-cell focused (4.2 V), lacks dual-cell regulation; no factory-set 8.40 V option; requires external resistor network for voltage setting | Not suitable for 2-cell Li-ion without redesign; intended for smartphones/tablets with single-cell batteries | Only consider BQ24075RGTR if migrating to single-cell architecture; MCP73213-F6TI/MF remains optimal for native dual-cell 8.40 V charging. |
Compared with MCP73213-A6S/MF, the MCP73213-F6TI/MF offers identical electrical performance and pin compatibility but ships with confirmed 8.40 V, 10% preconditioning, 6 hr elapse timer, 10% termination, 95% recharge, and Type 1 STAT - reducing qualification effort. Versus BQ24075RGTR, it provides native dual-cell support without external voltage-setting components or firmware dependency.

FAQ
What is the factory-preset charge voltage for MCP73213-F6TI/MF?
The MCP73213-F6TI/MF is factory preset to 8.40 V regulated output voltage with ±0.6% accuracy over –5°C to +55°C. This value is laser-trimmed and non-adjustable, ensuring precise dual-cell Li-ion termination without external resistors or calibration.
How does the PROG pin function in MCP73213-F6TI/MF?
In MCP73213-F6TI/MF, the PROG pin serves dual roles: it sets fast charge current via a resistor to VSS (130–1100 mA range), and acts as an enable input - applying ≥200 kΩ impedance places the device in standby mode, halting all charging activity until impedance drops.
What does "Type 1" status output mean for MCP73213-F6TI/MF?
"Type 1" status output in MCP73213-F6TI/MF means the STAT pin operates in on/off mode only - low during active charging (preconditioning, CC, CV), high-impedance at charge completion or shutdown. It does not flash, distinguishing it from Type 2 variants used for fault indication.
Does MCP73213-F6TI/MF include thermal protection?
Yes, MCP73213-F6TI/MF features both thermal regulation (dynamic current limiting based on die temperature) and thermal shutdown (suspends charging above 150°C, resumes after ~10°C cooldown). These functions protect the IC and battery during high-ambient or high-power conditions.
What is the input voltage range supported by MCP73213-F6TI/MF?
MCP73213-F6TI/MF operates from 4.2 V to 13 V input (VDD), with 4.15 V undervoltage lockout and 13 V overvoltage protection. Its absolute maximum rating is 18 V, allowing robust operation with low-cost wall adapters prone to voltage spikes during plug/unplug events.
