Product details
Overview
MCP73213T-B6SI/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 factory-preset 8.20V charge voltage, 10% preconditioning, 6-hour elapsed safety timer, and 10% end-of-charge current threshold for space-constrained portable devices.
For engineers reviewing the MCP73213T-B6SI/MF datasheet, MCP73213T-B6SI/MF pinout, MCP73213T-B6SI/MF application, or MCP73213T-B6SI/MF equivalent, this device supports precise dual-cell charging in cost-sensitive, thermally constrained designs requiring UVLO (4.15V), ±0.6% voltage regulation across –5°C to +55°C, and resistor-programmable fast charge current (130–1100 mA).
Technical Context
The MCP73213T-B6SI/MF implements a three-phase linear charge algorithm-preconditioning (10% of IREG, 32-minute timer), constant-current fast charge (programmed via RPROG), and constant-voltage regulation (8.20V ±0.6%)-with automatic recharge at 95% VREG. Its internal P-channel MOSFET features 350 mΩ typical RDS(ON) at 105°C.
Thermal regulation dynamically reduces charge current above ~110°C die temperature, while thermal shutdown suspends charging at 150°C (10°C hysteresis). Input protection includes 4.15V UVLO (100 mV hysteresis) and 13V OVP (150 mV hysteresis), enabling robust operation with low-cost wall adapters up to 18V absolute max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 8.20V ±0.6% over –5°C to +55°C - ensures safe, full-capacity charging of 2-cell Li-ion packs without overvoltage stress |
| Input OVP Threshold | 13.0V ±0.2V - protects against voltage spikes from unregulated AC-DC adapters |
| Fast Charge Current Range | 130–1100 mA via single RPROG - enables flexible design for 500–1100 mAh battery capacities |
| Preconditioning | 10% of IREG, 32-minute timer - safely recovers deeply depleted cells before fast charge |

Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) for enhanced heat dissipation in high-power linear charging applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1,2) | Battery management input supply | Accepts 4.2–13V input; 18V absolute max; bypassed with ≥1 μF capacitor; triggers UVLO/OVP protection |
| VBAT (Pins 3,4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to 2-cell battery positive; requires ≥1 μF bypass for stability |
| NC (Pins 5,6) | No connection | Unbonded pins; must remain floating; no PCB routing or soldering required |
| STAT (Pin 7) | Status output | Open-drain indicator: LOW during active charge, HIGH-Z at completion (Type 1 output per datasheet) |
| VSS (Pins 8,9) | 0V reference | Common ground return for battery negative and input supply; critical for current-sense accuracy |
| PROG (Pin 10) | Current regulation & enable | Sets fast charge current via resistor to VSS; >200 kΩ impedance places device in standby mode |
| EP (Pin 11) | Exposed thermal pad | Must be soldered to PCB copper pour with multiple thermal vias to maintain <62°C/W θJA |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | 350 mΩ RDS(ON) at 105°C eliminates external MOSFET and reduces BOM count by 3+ components |
| Factory-preset configuration | 8.20V VREG, 10% precondition, 6-hr timer, 10% ITERM, 95% VRTH, Type 1 STAT - enables drop-in use without configuration resistors |
| Input overvoltage protection | 13V OVP with 150 mV hysteresis - sustains operation through common wall-adapter transients without latch-off |
| Thermal regulation | Continuous current reduction above ~110°C - maintains safe junction temperature without abrupt shutdown during high-ambient charging |
| Reverse discharge protection | Sub-2 μA discharge current when VDD absent - prevents battery drain in standby or adapter-removed 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 | Factory preset to 8.40V charge voltage, same OVP (13V), precondition (10%), timer (6 hr), and STAT type | Designed for standard 4.2V/cell nominal batteries instead of 4.1V/cell configurations | Select when battery chemistry requires 8.40V termination (e.g., most commercial 2S Li-ion packs) |
| BQ24075RGTR | Single-cell only; 4.2V fixed output; no factory-programmed options; requires external resistor for current set | Lacks dual-cell support, preconditioning, and auto-recharge - unsuitable for 2S systems without redesign | Consider only for new single-cell designs where Microchip's integrated protection and preset flexibility are not required |
Compared with MCP73213-A6S/MF, the MCP73213T-B6SI/MF provides lower 8.20V termination for aging or high-impedance 2S packs, while BQ24075RGTR lacks dual-cell capability entirely - making it incompatible without topology change.

FAQ
What is the factory-preset charge voltage for MCP73213T-B6SI/MF?
The MCP73213T-B6SI/MF is factory configured for 8.20V regulated charge voltage with ±0.6% tolerance over –5°C to +55°C. This value is laser-trimmed and non-adjustable, targeting dual-cell Li-ion batteries with lower nominal voltages or aged cells requiring reduced termination voltage to extend cycle life.
Does MCP73213T-B6SI/MF require external MOSFETs or current-sense resistors?
No. The MCP73213T-B6SI/MF integrates a P-channel MOSFET with 350 mΩ typical RDS(ON), on-chip current sensing, and reverse discharge protection. This eliminates the need for external power FETs, sense resistors, and associated gate-drive circuitry - reducing total solution footprint and BOM cost.
How does the preconditioning function operate in MCP73213T-B6SI/MF?
The MCP73213T-B6SI/MF enters preconditioning mode when VBAT falls below 71.5% of 8.20V (≈5.86V). It then delivers 10% of the programmed fast-charge current for up to 32 minutes to safely recover deeply depleted cells before initiating constant-current charging.
What protection features are built into MCP73213T-B6SI/MF?
The MCP73213T-B6SI/MF includes input overvoltage protection (13V), undervoltage lockout (4.15V), thermal regulation (current reduction above ~110°C), thermal shutdown (150°C), battery short protection (25 mA recovery current), and automatic power-down when VDD drops within 50 mV of VBAT.
Can MCP73213T-B6SI/MF be used in standalone applications without a microcontroller?
Yes. The MCP73213T-B6SI/MF is designed for both standalone and host-controlled operation. Its STAT pin provides Type 1 (On/Off) status indication compatible with direct LED drive, and all charge parameters are factory preset - requiring only VDD, VBAT, PROG resistor, and bypass capacitors for full functionality.
