Product details
Overview
MCP73113T-06SI/MF from Microchip Technology is a single-cell Li-ion/Li-polymer linear battery charge management controller with integrated pass transistor, current sense, input overvoltage protection (6.5 V), and reverse discharge protection. It delivers 4.20 V regulated charge voltage ±0.5% over –5°C to +55°C, supports 130–1100 mA resistor-programmable fast charge current, and operates across –40°C to +85°C ambient. It is used in USB-powered portable media players requiring compact, cost-sensitive, thermally regulated charging.
For engineers reviewing the MCP73113T-06SI/MF datasheet, MCP73113T-06SI/MF pinout, MCP73113T-06SI/MF application, or MCP73113T-06SI/MF equivalent, this page provides verified functional specifications, DFN-10 package layout, factory-preset 4.20 V / 6.5 V OVP / 10% preconditioning / 32-minute timer / 6-hour elapse safety timer / 10% end-of-charge threshold / 95% auto-recharge / Type 1 status output - all confirmed for this exact variant.
Technical Context
The MCP73113T-06SI/MF implements a three-phase linear charge algorithm: preconditioning (10% of IREG at VBAT < 71.5% × VREG), constant-current fast charge (programmed via RPROG), and constant-voltage regulation (4.20 V). It integrates thermal regulation (current reduction above ~105°C) and hard thermal shutdown at 150°C with 10°C hysteresis.
Its protection architecture includes input overvoltage lockout (6.5 V start, 150 mV hysteresis), undervoltage lockout (4.15 V start, 100 mV hysteresis), battery short-circuit detection (1.7 V threshold), and automatic power-down when VDD falls within +50 mV of VBAT. The STAT pin provides open-drain Type 1 status (high-Z at shutdown/standby/charge-complete; low during active charging phases).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 4.20 V ±0.5% over –5°C to +55°C - ensures precise Li-ion cell termination without overvoltage stress. |
| Input OVP Threshold | 6.5 V (MCP73113 variant) - protects against wall-adapter spikes up to 18 V absolute max input. |
| Fast Charge Current Range | 130–1100 mA, set by single RPROG (1–21 kΩ) - enables flexible design for 500–1000 mAh batteries. |
| Preconditioning | Enabled at 10% of IREG, VPTH/VREG = 71.5% - safely recovers deeply depleted cells before CC mode. |
| End-of-Charge Termination | 10% IREG threshold with 1 ms filtering - prevents false cutoff during transient load events. |
| Elapse Safety Timer | 6 hours - halts charging if CV phase exceeds safe duration, preventing thermal runaway. |
| Auto-Recharge Threshold | 95% of VREG - restarts charging when battery self-discharge drops voltage to 4.0 V (for 4.2 V setting). |
| Operating Temperature | –40°C to +85°C ambient - validated for industrial and consumer handheld environments. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) for enhanced heat dissipation in high-current linear operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2) | Battery management input supply | Accepts 4.2–6.5 V input; rated to 18 V absolute max; bypass with ≥1 µF capacitor to VSS. |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to battery anode; bypass with ≥1 µF capacitor. |
| NC (Pins 5, 6) | No connect | Unbonded pins; must remain unconnected on PCB. |
| STAT (Pin 7) | Status output | Open-drain Type 1 output - low during charging, high-Z at shutdown/standby/charge-complete. |
| VSS (Pins 8, 9) | 0 V reference | Common ground return for battery cathode, input supply negative, and bypass capacitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear Li-ion charge management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP73113-06S/MF | Identical factory preset (4.20 V, 6.5 V OVP, 10% precondition, 32-min timer, 6-hr elapse, 10% ITERM, 95% recharge, Type 1 STAT), same DFN-10 package, but lacks 'T' suffix indicating tape-and-reel packaging option. | Same functional behavior; differs only in packaging format - bulk vs. tape-and-reel - with identical electrical and thermal specs. | Select MCP73113T-06SI/MF for automated SMT assembly; choose MCP73113-06S/MF for manual prototyping or low-volume hand-soldering. |
| MCP73114-0NS/MF | OVP threshold reduced to 5.8 V (vs. 6.5 V); otherwise identical preset values (4.20 V, 10% precondition, 32-min timer, 6-hr elapse, 10% ITERM, 95% recharge, Type 1 STAT) and DFN-10 package. | Designed for lower-input-voltage systems (e.g., 5 V-only USB ports without adapter ripple); not suitable where 6.5 V OVP margin is required for wall-wart compatibility. | Choose MCP73114-0NS/MF only when input source is strictly regulated ≤5.5 V; use MCP73113T-06SI/MF for universal AC-DC adapter support. |
Compared with MCP73113-06S/MF, the 'T' suffix denotes tape-and-reel delivery for production SMT lines; compared with MCP73114-0NS/MF, the higher 6.5 V OVP enables robust operation with low-cost wall adapters prone to voltage spikes.

FAQ
What is the factory-set charge voltage and OVP threshold for MCP73113T-06SI/MF?
The MCP73113T-06SI/MF is factory preset to 4.20 V regulated charge voltage and 6.5 V overvoltage protection (OVP) threshold. These values are laser-trimmed and non-adjustable; they match the MCP73113-06S/MF variant and differ from the MCP73114 series (5.8 V OVP). This configuration ensures compatibility with standard 4.2 V Li-ion cells and robustness against 5 V adapter transients.
How does the PROG pin function in MCP73113T-06SI/MF beyond setting charge current?
In addition to programming fast charge current via resistor-to-VSS, the PROG pin serves as the primary enable/disable control for MCP73113T-06SI/MF. When left floating or connected to impedance >200 kΩ, the device enters standby mode with <150 µA quiescent current. This dual-role simplifies system-level power sequencing and eliminates need for external enable logic in battery-powered devices.
What does "Type 1" status output mean for MCP73113T-06SI/MF?
"Type 1" refers to the STAT pin behavior of MCP73113T-06SI/MF: it outputs low during all active charge phases (preconditioning, fast charge, constant voltage) and goes high-impedance (not flashing) at shutdown, standby, and charge-complete states. This differs from Type 2, which flashes during faults - making Type 1 ideal for simple LED indication without microcontroller polling.
Does MCP73113T-06SI/MF support automatic recharge, and at what threshold?
Yes, MCP73113T-06SI/MF supports automatic recharge at 95% of its 4.20 V regulated voltage - i.e., 4.0 V. When battery voltage drops to this level after charge completion, the device autonomously restarts the full charge cycle. This feature is factory enabled and requires no external components, ensuring consistent top-up for intermittently used devices like Bluetooth headsets.
What thermal protection mechanisms are implemented in MCP73113T-06SI/MF?
MCP73113T-06SI/MF features two-tier thermal protection: (1) thermal regulation - gradual current reduction beginning around 105°C to maintain safe junction temperature while sustaining partial charge; and (2) thermal shutdown - hard cutoff at 150°C with 10°C hysteresis. Both are inherent to the silicon design and require no external sensors or feedback loops.
