Product details

Overview

MCP73213-A61I/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 factory-preset 8.40 V charge 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-A61I/MF datasheet, MCP73213-A61I/MF pinout, MCP73213-A61I/MF application, or MCP73213-A61I/MF equivalent, key selection criteria include its 8.40 V regulated output, 13 V input OVP threshold, 10% preconditioning option, 6-hour elapse timer, and Type 1 (On/Off) STAT output behavior - all confirmed for this exact variant per Microchip DS20002190D.

Technical Context

The MCP73213-A61I/MF implements a three-phase linear charging algorithm: preconditioning (10% of I_REG at V_BAT < 71.5% × V_REG), constant-current fast charge (programmed via R_PROG), then constant-voltage regulation at 8.40 V ±0.6%. Its internal P-channel MOSFET features 350 mΩ typical R_DS(ON) at 105°C, enabling direct connection to 2-cell battery packs without external FETs.

Thermal regulation dynamically reduces charge current above ~110°C die temperature, while hard thermal shutdown triggers at 150°C with 10°C hysteresis. Input UVLO (4.15 V start, 4.05 V stop) and OVP (13 V threshold, 150 mV hysteresis) ensure robust operation with low-cost wall adapters prone to voltage spikes.

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 termination without external feedback.
Input OVP Threshold	13.0 V ±0.2 V - protects against voltage spikes from unregulated AC-DC adapters up to 18 V absolute max.
Fast Charge Current	Resistor-programmable 130–1100 mA - enables design flexibility for 500–1200 mAh battery packs.
Preconditioning	Enabled at 10% of I_REG, V_PTH/V_REG = 71.5% - safely recovers deeply depleted cells before full-rate charging.
Elapse Timer	6 hours - prevents indefinite charging during fault conditions like open thermistor or failed battery.
STAT Output	Type 1 (On/Off) - provides simple LED indication: low during active charge, high-Z at completion or fault.

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 charge voltage, 13 V OVP, and 10% preconditioning; differs only in STAT output type (Type 1 vs Type 2 flashing).	Same functional role; Type 2 STAT provides flashing fault indication instead of On/Off.	Select MCP73213-A6S/MF if visual fault differentiation (e.g., flashing for thermal fault) is required over simple On/Off status.
BQ24075RGTR	Single-cell only (4.2 V), no factory preset OVP (requires external resistor), lacks integrated reverse discharge protection.	Requires redesign for dual-cell topology; needs external components for OVP and reverse blocking.	Only consider BQ24075RGTR if migrating to single-cell architecture and accepting added BOM complexity and reduced integration.

Compared with MCP73213-A6S/MF, the MCP73213-A61I/MF offers identical core charging functionality but uses Type 1 STAT output for simpler LED interface; versus BQ24075RGTR, it delivers true dual-cell support with higher integration, eliminating external OVP and reverse-blocking components required by the TI part.

FAQ

What is the factory-preset charge voltage for MCP73213-A61I/MF?

The MCP73213-A61I/MF is factory configured for 8.40 V constant-voltage regulation, with ±0.6% accuracy over –5°C to +55°C. This value is laser-trimmed during manufacturing and cannot be adjusted externally - it matches the nominal voltage of two fully charged Li-ion cells (4.20 V × 2). The MCP73213-A61I/MF does not support user-selectable voltage options.

Does MCP73213-A61I/MF include input overvoltage protection, and what is its threshold?

Yes, the MCP73213-A61I/MF integrates input overvoltage protection with a nominal threshold of 13.0 V and ±0.2 V tolerance. When VDD exceeds this level, the device shuts down charging and sets STAT to high-impedance. Recovery occurs automatically once VDD falls below 12.85 V due to 150 mV hysteresis. This feature allows direct use with low-cost, unregulated wall adapters without external TVS diodes.

How is fast charge current programmed on MCP73213-A61I/MF?

Fast charge current on the MCP73213-A61I/MF is set using a single resistor (R_PROG) connected between the PROG pin and VSS. The relationship is I_REG = 1104 / R_PROG (with R_PROG in kΩ and I_REG in mA), supporting 130–1100 mA. For example, a 2.2 kΩ resistor yields ~500 mA. The MCP73213-A61I/MF datasheet Table 5-1 lists standard E24/E96 values for common currents.

What does the "A61I/MF" suffix indicate in MCP73213-A61I/MF?

The "A61I/MF" suffix identifies a specific factory configuration: "A" denotes 8.40 V charge voltage, "61" indicates 10% preconditioning current ratio and 6-hour elapse timer, "I" specifies industrial temperature range (–40°C to +85°C), and "/MF" signifies the 10-lead DFN package with exposed pad. This exact variant is documented in Microchip DS20002190D Table 2 as a standard sample option.

Can MCP73213-A61I/MF operate without a host microcontroller?

Yes, the MCP73213-A61I/MF is designed for fully autonomous operation. It executes the complete CC/CV charge algorithm - including preconditioning, fast charge, constant voltage regulation, end-of-charge detection (10% I_REG), automatic recharge (95% V_REG), and fault handling - without any host MCU involvement. Its Type 1 STAT output provides direct LED status indication, making it ideal for stand-alone portable chargers and cradles.
