Product details
Overview
MCP73213T-A6W/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-A6W/MF datasheet, MCP73213T-A6W/MF pinout, MCP73213T-A6W/MF application, or MCP73213T-A6W/MF equivalent, key selection criteria include factory-preset 8.40 V charge voltage, 10% preconditioning option, 6-hour elapse safety timer, 95% automatic recharge threshold, and DFN-10 (3 mm × 3 mm) package with exposed thermal pad.
Technical Context
The MCP73213T-A6W/MF implements a full CC/CV charge algorithm with factory-preset 8.40 V regulation, 13 V input OVP, and –40°C to +85°C operational range. Its thermal regulation dynamically limits charge current above ~110°C junction temperature, while die-level thermal shutdown activates at 150°C with 10°C hysteresis.
It integrates input UVLO (4.15 V start), battery short protection (3.4 V threshold, 25 mA recovery current), and programmable end-of-charge termination (10% IREG). The PROG pin serves dual roles: fast charge current setting via external resistor and enable control-high-impedance (>200 kΩ) forces standby mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 8.40 V ±0.6% over –5°C to +55°C - ensures precise dual-cell Li-ion stack regulation without external feedback. |
| Input OVP Threshold | 13.0 V ±0.2 V - protects against wall-adapter spikes and enables use in cost-sensitive AC-DC environments. |
| Fast Charge Current Range | 130–1100 mA set by single PROG-to-VSS resistor - simplifies design and eliminates need for current-sense amplifier or DAC. |
| Preconditioning | Enabled at 71.5% of VREG (6.01 V), 10% IREG - safely recovers deeply depleted 2-cell batteries before fast charge. |
| Elapse Safety Timer | 6 hours - prevents indefinite charging under fault conditions while supporting typical 2-cell 800–1200 mAh packs. |
| Automatic Recharge | Enabled at 95% of VREG (7.98 V) - maintains full capacity in intermittently powered portable devices. |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - achieves θJA = 62°C/W on 4-layer board for thermal-limited linear operation. |
Pinout & Package
DFN-10 (3 mm × 3 mm) package with exposed thermal pad (EP) for enhanced heat dissipation. Pin 1–10 arranged per top-view layout; 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; internal UVLO (4.15 V) and OVP (13 V) active here. |

| NC (Pins 5,6) | No connection | Unbonded; must remain floating - no routing or stitching required. |
| STAT (Pin 7) | Status output | Open-drain indicator: low during active charge, high-Z at completion; drives LED or MCU GPIO. |
| VSS (Pins 8,9) | 0 V reference | Common ground return for battery negative, input supply, and all internal circuitry. |
| PROG (Pin 10) | Current regulation & enable | Resistor sets fast charge current (IREG); >200 kΩ impedance forces standby mode. |
| EP (Pin 11) | Exposed thermal pad | Internally connected to VSS; must be soldered to PCB ground plane with ≥4 thermal vias for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | 350 mΩ RDS(on) at 105°C - eliminates external MOSFET and reduces BOM count in space-constrained designs. |
| Input overvoltage protection | 13 V threshold with 150 mV hysteresis - enables direct use with unregulated wall adapters without external TVS. |
| Factory-preset charge parameters | 8.40 V regulation, 10% preconditioning, 6 hr timer, 10% termination, 95% recharge - eliminates configuration resistors or firmware setup. |
| Thermal regulation | Dynamic current limiting based on die temperature - maintains safe operation without external thermal sensors or shutdown logic. |
| Reverse discharge protection | Sub-2 μA leakage when VDD absent - prevents battery drain through input path in standby or unplugged states. |

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, and 6 hr timer; differs only in STAT output type (Type 1 On/Off vs. Type 2 Flashing). | Same functional behavior; Type 1 STAT suits simple LED indication, Type 2 supports multi-state visual feedback. | Select MCP73213T-A6W/MF when flashing STAT pattern is required for user-facing status indication. |
| BQ24075RGTR | Single-cell only (4.2 V), no factory preset OVP (requires external resistor), no integrated battery short protection, different pinout. | Not suitable for dual-cell stacks; requires additional components for OVP and short detection; lacks preconditioning timer. | Choose only if migrating from single-cell design; MCP73213T-A6W/MF provides complete dual-cell solution with no external protection needed. |
Compared with MCP73213-A6S/MF, MCP73213T-A6W/MF offers identical regulation and safety features but adds flashing STAT for enhanced user feedback; versus BQ24075RGTR, it delivers native dual-cell support, integrated OVP, and battery short protection-reducing bill-of-materials and layout complexity.

FAQ
What is the factory-preset charge voltage for MCP73213T-A6W/MF?
The MCP73213T-A6W/MF is factory preset to 8.40 V ±0.6% regulation voltage over –5°C to +55°C. This value is laser-trimmed and non-adjustable, ensuring precise dual-cell Li-ion stack termination without external feedback components or calibration.
How does the PROG pin function in MCP73213T-A6W/MF?
In MCP73213T-A6W/MF, the PROG pin sets fast charge current via an external resistor (130–1100 mA range) and also acts as an enable input: applying >200 kΩ impedance places the device in standby mode, halting all charging activity until impedance drops below threshold.
Does MCP73213T-A6W/MF include input overvoltage protection?
Yes, MCP73213T-A6W/MF includes integrated input overvoltage protection with a 13.0 V ±0.2 V threshold and 150 mV hysteresis. This allows direct connection to low-cost wall adapters without external TVS diodes or clamping circuits.
What is the purpose of the exposed thermal pad (EP) on MCP73213T-A6W/MF?
The exposed thermal pad (EP) on MCP73213T-A6W/MF is internally connected to VSS and must be soldered to a PCB ground plane with ≥4 thermal vias. It reduces θJA to 62°C/W, enabling higher sustained charge currents without thermal shutdown in compact layouts.
How does MCP73213T-A6W/MF handle deeply depleted batteries?
MCP73213T-A6W/MF enters preconditioning mode when VBAT falls below 71.5% of VREG (6.01 V), delivering 10% of the programmed fast charge current until the battery reaches the fast-charge threshold - preventing damage to over-discharged dual-cell Li-ion packs.
