Product details
Overview
MCP73113-06SI/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 in space-constrained portable devices.
For engineers reviewing the MCP73113-06SI/MF datasheet, MCP73113-06SI/MF pinout, MCP73113-06SI/MF application, or MCP73113-06SI/MF equivalent, this page provides verified technical context, validated pin functions, confirmed charge algorithm behavior (CC/CV with thermal regulation), factory-set 4.20 V / 6.5 V OVP / 10% preconditioning / 32-min timer / 6-hr elapse safety timer / 10% end-of-charge threshold / 95% auto-recharge, and DFN-10 package implementation details.
Technical Context
The MCP73113-06SI/MF implements a fully integrated linear charging architecture with internal P-channel MOSFET pass element (350 mΩ typical RDS(on)), precision voltage reference (1.21 V), and dual-loop control: constant-current regulation via PROG pin resistor feedback and constant-voltage regulation at factory-trimmed 4.20 V with ±0.5% tolerance across temperature.
Its protection stack includes input overvoltage lockout (6.5 V start, 150 mV hysteresis), undervoltage lockout (4.15 V start, 100 mV hysteresis), thermal regulation (current reduction above ~105°C), thermal shutdown (150°C trip, 10°C hysteresis), and battery short-circuit detection (1.7 V threshold, 25 mA recovery current).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 4.20 V ±0.5% over –5°C to +55°C - ensures safe, full-capacity charging of standard Li-ion cells without overvoltage risk. |
| Input OVP Threshold | 6.5 V (MCP73113 variant) - protects against wall-adapter spikes and enables use with low-cost 5 V supplies subject to transient overshoot. |
| Fast Charge Current Range | 130–1100 mA via external PROG resistor - allows flexible design for 800–2000 mAh batteries with minimal BOM count. |
| Preconditioning | Enabled at 10% of IREG, 71.5% VREG threshold, 32-minute timer - safely recovers deeply depleted cells before CC mode. |
| End-of-Charge Termination | 10% IREG minimum current ratio - balances full charge completion against excessive time in CV phase for cycle life. |
| Auto-Recharge Threshold | 95% of VREG (i.e., 3.99 V) - triggers recharge when battery self-discharge drops voltage below safe operating level. |
| Package | DFN-10 (3 mm × 3 mm) with exposed thermal pad - enables high-power dissipation in ultra-compact footprint for handhelds. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP); EP must be soldered to PCB copper for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 1, 2) | Battery management input supply | Accepts 4.2–6.5 V input; absolute max 18 V; powers internal circuitry and gate drive; bypass required with ≥1 µF to VSS. |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to battery anode; regulates voltage/current; requires ≥1 µF bypass to VSS. |
| NC (Pins 5, 6) | No connect | Unbonded pins; must remain unconnected per datasheet; no routing or stitching allowed. |
| STAT (Pin 7) | Status output | Open-drain logic output; low during active charge (precondition, CC, CV); high-Z at shutdown, standby, or charge complete (Type 1). |
| VSS (Pins 8, 9) | Ground reference | Common return for battery cathode, input supply negative, and all internal bias circuits; must be low-impedance star point. |
| PROG (Pin 10) | Current regulation & enable | Resistor-to-VSS sets fast charge current; floating or >200 kΩ disables charger; also serves as enable pin. |
| EP (Pin 11) | Exposed thermal pad | Internally connected to VSS; must be soldered to large PCB copper pour with multiple thermal vias for junction temp control. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | Internal P-channel MOSFET (350 mΩ RDS(on)) eliminates external FET, reducing board area and component count. |
| Factory-trimmed voltage regulation | 4.20 V ±0.5% over –5°C to +55°C - eliminates need for external voltage-setting resistors or calibration. |
| Input overvoltage protection | 6.5 V OVP with 150 mV hysteresis - prevents damage from adapter transients without external TVS diodes. |
| Thermal regulation + shutdown | Gradual current reduction above ~105°C + hard shutdown at 150°C - maintains reliability under high ambient or poor heatsinking. |
| Preconditioning & safety timers | 32-minute precondition timer + 6-hour elapsed safety timer - prevents indefinite trickle charge and thermal runaway. |
| Reverse discharge protection | Blocks battery-to-input current flow when VDD is absent - preserves battery charge during system standby or adapter removal. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-cell Li-ion linear charge management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP73113-16SI/MF | Factory-set 4.10 V charge voltage, same 6.5 V OVP, 10% preconditioning, 32-min timer, 6-hr elapse timer, 10% termination, 95% auto-recharge. | Suitable for legacy Li-ion cells requiring lower termination voltage to extend cycle life at expense of capacity. | Select when battery chemistry specifies 4.10 V nominal full-charge voltage and thermal margin is prioritized over runtime. |
| MCP73114-0NSI/MF | Same 4.20 V charge voltage but 5.8 V OVP threshold; identical preconditioning, timer, termination, and auto-recharge settings. | Required for systems where input supply may exceed 6.0 V but must remain below 5.8 V OVP threshold (e.g., regulated 5.5 V sources). | Choose when tighter input voltage control exists and 6.5 V OVP is unnecessarily conservative for the power supply design. |
Compared with MCP73113-16SI/MF and MCP73114-0NSI/MF, the MCP73113-06SI/MF uniquely balances 4.20 V capacity optimization with 6.5 V OVP robustness for unregulated 5 V adapters - making it optimal for cost-sensitive consumer electronics where both runtime and spike resilience matter.

FAQ
What is the factory-set charge voltage and OVP threshold for MCP73113-06SI/MF?
The MCP73113-06SI/MF is factory-configured for 4.20 V battery regulation voltage with ±0.5% tolerance over –5°C to +55°C and 6.5 V input overvoltage protection (OVP) start threshold with 150 mV hysteresis. These values are laser-trimmed during production and cannot be modified externally - they define the core charging behavior of the MCP73113-06SI/MF in all operating conditions.
How does the PROG pin function in MCP73113-06SI/MF beyond setting charge current?
In addition to programming fast charge current via an external resistor to VSS, the PROG pin on the MCP73113-06SI/MF serves as the primary enable/disable control: floating the pin or connecting it to impedance >200 kΩ places the MCP73113-06SI/MF into shutdown mode with zero quiescent current (≤5 µA), while pulling it to VSS below 100 mV initiates charging - enabling simple hardware-based charge control without a microcontroller.
What thermal protection mechanisms does MCP73113-06SI/MF implement?
The MCP73113-06SI/MF features two-tier thermal protection: first, continuous thermal regulation that gradually reduces charge current above ~105°C to maintain safe junction temperature; second, hard thermal shutdown at 150°C (±5°C) with 10°C hysteresis that suspends all charging until die cools - both mechanisms are implemented in silicon and require no external components, ensuring reliability of the MCP73113-06SI/MF under sustained high-power or high-ambient conditions.
Can MCP73113-06SI/MF be used with batteries requiring 4.35 V or 4.40 V charge voltage?
No - the MCP73113-06SI/MF is factory-trimmed exclusively for 4.20 V regulation and cannot be reconfigured for 4.35 V or 4.40 V operation. For those voltages, Microchip offers distinct part numbers: MCP73113-25SI/MF (4.35 V) and MCP73113-30SI/MF (4.40 V). Using MCP73113-06SI/MF with higher-voltage cells risks undercharging and reduced capacity, while forcing voltage adjustment violates the MCP73113-06SI/MF's fixed internal reference architecture.
What is the role of the NC pins (5 and 6) on the MCP73113-06SI/MF DFN-10 package?
Pins 5 and 6 of the MCP73113-06SI/MF are designated No Connect (NC) - they are physically present but internally unbonded and electrically isolated. Per Microchip's datasheet DS20002183E, these pins must remain unconnected on the PCB; routing traces to them, applying solder mask openings, or using them for mechanical anchoring violates the MCP73113-06SI/MF's qualified layout and may compromise thermal performance or ESD robustness.
