Product details
Overview
MCP73213-A5JI/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 8.40V 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 MCP73213-A5JI/MF datasheet, MCP73213-A5JI/MF pinout, MCP73213-A5JI/MF application, or MCP73213-A5JI/MF equivalent, this page provides verified technical context, factory-preset configuration details (8.40V VREG, 10% preconditioning, 32-min timer, 10% end-of-charge threshold, 95% recharge, Type 1 status output), thermal shutdown at 150°C, and DFN-10 package layout for compact PCB integration.
Technical Context
The MCP73213-A5JI/MF implements a full CC/CV charging algorithm optimized for 2-cell Li-ion/Li-polymer batteries, with factory-preset 8.40V regulation voltage and ±0.6% accuracy over –5°C to +55°C. Its integrated P-channel MOSFET (350 mΩ RDS(on)) enables direct battery connection without external power switches.
Charge control logic includes undervoltage lockout (4.15V start), input overvoltage protection (13V threshold), automatic preconditioning (10% of IREG), and thermal regulation that dynamically reduces current above ~110°C to maintain reliability. The PROG pin serves dual roles: programming fast charge current via external resistor and enabling/disabling charge via high-impedance detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulated Charge Voltage | 8.40V ±0.6% over –5°C to +55°C - ensures safe, full capacity charging for 2-cell Li-ion packs without overvoltage risk. |
| Input Overvoltage Protection | 13.0V ±0.2V threshold - protects against wall-wart spikes and unregulated adapters up to 18V absolute max. |
| Fast Charge Current Range | 130–1100 mA set by single PROG-to-VSS resistor - enables precise current tuning for battery capacity and thermal constraints. |
| Preconditioning Threshold | 71.5% of VREG (6.01V) - initiates 10% fast-charge current for deeply depleted cells before CC mode. |
| End-of-Charge Termination | 10% of IREG current ratio - stops charging when battery draws ≤10% of programmed fast-charge current in CV mode. |
| Recharge Threshold | 95% of VREG (7.98V) - restarts charging automatically when battery voltage drops below this level post-full-charge. |
| Thermal Shutdown | 150°C die temperature with 10°C hysteresis - halts charging during sustained overheating and resumes only after cooling. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) for enhanced heat dissipation in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2) | Battery management input supply | Accepts 4.2–13V input; internal UVLO (4.15V) and OVP (13V) protect system; bypass with ≥1 µF capacitor. |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to 2-cell battery positive; requires ≥1 µF output capacitor for stability. |
| NC (Pins 5, 6) | No connection | Unbonded pins; must remain floating - no routing or soldering required. |
| STAT (Pin 7) | Status output | Open-drain indicator: low during active charge, high-Z at completion (Type 1); drives LED or microcontroller GPIO. |
| VSS (Pins 8, 9) | Ground reference | Common return for battery negative, input supply, and all internal circuitry; connect to PCB ground plane. |
| PROG (Pin 10) | Current regulation & enable | Resistor-to-VSS sets fast charge current; >200 kΩ impedance forces standby mode - no external enable signal needed. |
| EP (Pin 11) | Exposed thermal pad | Must be soldered to large copper pour with multiple thermal vias - critical for thermal regulation performance and 125°C max junction operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | 350 mΩ RDS(on) P-MOSFET eliminates need for external switch and simplifies BOM in cost-sensitive portable designs. |
| Factory-preset charge profile | 8.40V VREG, 10% preconditioning, 32-min timer, 10% termination, 95% recharge, Type 1 STAT - reduces design time vs. programmable alternatives. |
| Input overvoltage protection | 13V OVP with 150 mV hysteresis prevents damage from low-cost AC-DC adapters and plug/unplug transients. |
| Thermal regulation | Dynamic current reduction above ~110°C maintains safe die temperature while maximizing charge rate under ambient load. |
| Automatic power-down | Enters shutdown when VDD falls within +50 mV of VBAT - prevents reverse battery discharge when input is removed. |

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 package and pinout; same 8.40V VREG but configured with 6-hour elapsed timer (vs. 8-hour default in A5JI/MF). | Suitable for applications requiring stricter charge duration limits to prevent over-stress on aging batteries. | Select A6S/MF if fixed 6-hr safety timer is preferred over A5JI/MF's 8-hr option. |
| BQ24075RGTR | TI part in QFN-16; supports 8.4V but lacks integrated OVP and uses external MOSFET; requires additional components for 13V protection. | Used in higher-current (>1.5A) or multi-chemistry designs where flexibility outweighs component count. | Choose BQ24075RGTR only when external OVP and MOSFET selection are acceptable for added design complexity. |
Compared with MCP73213-A5JI/MF, the A6S/MF offers identical core functionality with tighter elapsed timing, while BQ24075RGTR trades integration for configurability - making A5JI/MF optimal for minimal-BOM, cost-sensitive dual-cell Li-ion chargers.

FAQ
What is the factory-preset charge voltage for MCP73213-A5JI/MF?
The MCP73213-A5JI/MF is factory preset to 8.40V regulated output voltage with ±0.6% accuracy over –5°C to +55°C. This value is laser-trimmed during production and cannot be adjusted externally - ensuring consistent, safe charging for 2-cell Li-ion battery packs without calibration overhead.
How does MCP73213-A5JI/MF handle input overvoltage conditions?
MCP73213-A5JI/MF incorporates an internal overvoltage protection circuit with a 13.0V ±0.2V threshold. When input voltage exceeds this level, the device immediately suspends charging, places STAT in high-impedance state, and holds the condition until VDD falls below the hysteresis point (≈12.85V). This protects downstream circuitry from wall-wart spikes and unregulated adapter surges.
What is the function of the PROG pin on MCP73213-A5JI/MF?
The PROG pin on MCP73213-A5JI/MF serves two functions: (1) it sets fast charge current via an external resistor to VSS (130–1100 mA range), and (2) it acts as an enable/disable input - applying >200 kΩ impedance forces the device into standby mode. No separate enable signal is required, simplifying system-level control.
Does MCP73213-A5JI/MF support automatic recharge, and at what threshold?
Yes, MCP73213-A5JI/MF supports automatic recharge at a factory-set threshold of 95% of its regulated voltage (7.98V for 8.40V VREG). When battery voltage drops below this level after charge completion, the device autonomously restarts the full CC/CV cycle - eliminating need for host MCU polling or external wake-up circuitry.
What thermal management features does MCP73213-A5JI/MF include?
MCP73213-A5JI/MF integrates both thermal regulation and thermal shutdown. Thermal regulation begins reducing charge current above ~110°C to maintain safe die temperature, while thermal shutdown halts all charging at 150°C with 10°C hysteresis. The exposed thermal pad (EP) must be soldered to a PCB copper pour with multiple vias to achieve specified θJA = 62°C/W.
