Product details
Overview
MCP73113-16SI/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 4.10 V regulated charge voltage, 10% preconditioning current ratio, 32-minute precondition timer, 6-hour elapsed safety timer, and 10% end-of-charge current threshold. It is used in compact USB-powered portable devices requiring safe, thermally regulated charging.
For engineers reviewing the MCP73113-16SI/MF datasheet, MCP73113-16SI/MF pinout, MCP73113-16SI/MF application, or MCP73113-16SI/MF equivalent, key selection criteria include factory-preset 4.10 V regulation, 6.5 V OVP threshold, Type 1 status output (high-Z fault indication), -40°C to +85°C operating range, and DFN-10 (3 mm × 3 mm) thermal-pad package compatibility.
Technical Context
The MCP73113-16SI/MF implements a three-phase linear charging algorithm-preconditioning (10% IREG, 32 min max), constant-current fast charge (programmable 130–1100 mA via PROG resistor), and constant-voltage regulation (4.10 V ±0.5% across -5°C to +55°C). It integrates thermal regulation to dynamically reduce charge current above ~105°C and suspends charging at 150°C die temperature with 10°C hysteresis.
Its protection architecture includes input overvoltage lockout at 6.5 V (150 mV hysteresis), undervoltage lockout at 4.15 V (100 mV hysteresis), battery short-circuit detection at 1.7 V, and automatic recharge at 95% of VREG. The PROG pin serves dual function: programming fast-charge current and enabling/disabling charge via high-impedance (>200 kΩ) assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Voltage | 4.10 V ±0.5% over -5°C to +55°C - ensures precise cell voltage control to prevent overcharge and maximize cycle life. |
| Input OVP Threshold | 6.5 V (MCP73113 variant) - protects against wall-adapter spikes and enables use with low-cost AC-DC supplies up to 18 V absolute max. |
| Precondition Current Ratio | 10% of IREG - safely recovers deeply depleted Li-ion cells before full-rate charging begins. |
| Elapsed Safety Timer | 6 hours - prevents indefinite charging under fault conditions; terminates cycle if CV phase exceeds duration. |
| End-of-Charge Current Ratio | 10% of IREG - defines termination threshold for CV phase, balancing capacity recovery and safety. |
| Automatic Recharge Threshold | 95% of VREG (3.90 V) - triggers new charge cycle when battery self-discharges to maintain full state-of-charge. |
| Status Output Type | Type 1 (high-Z fault) - provides open-drain logic output compatible with LED indicators or microcontroller GPIO without external pull-up for fault signaling. |
Pinout & Package
Package: 10-lead DFN (3 mm × 3 mm) with exposed thermal pad (EP) for enhanced power dissipation; RoHS-compliant, moisture-sensitive level 3.
| 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 for stability. |
| VBAT (Pins 3, 4) | Battery charge control output | Drain of internal P-MOSFET; connects directly to battery anode; requires ≥1 µF bypass for loop stability. |
| NC (Pins 5, 6) | No connect | Unbonded pins; must remain unconnected on PCB. |
| STAT (Pin 7) | Status output | Open-drain output indicating charge state (low during active charge, high-Z at completion/fault). |
| VSS (Pins 8, 9) | 0 V reference | Common ground return for battery cathode and input supply; must be low-impedance connection. |
| PROG (Pin 10) | Current regulation & enable | Resistor-to-VSS sets fast-charge current; floating or >200 kΩ disables charger (standby mode). |
| EP (Pin 11) | Exposed thermal pad | Must be soldered to PCB copper pour with multiple thermal vias to improve θJA (64°C/W typical). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pass transistor | 350 mΩ RDS(on) at 105°C - eliminates external MOSFET, reduces BOM count and layout area in space-constrained designs. |
| Thermal regulation | Dynamic current reduction above ~105°C - maintains safe die temperature without external sensors or feedback loops. |
| Factory-preset configuration | Fixed 4.10 V VREG, 6.5 V OVP, 10% precondition, 32-min timer, 6-hr elapsed timer, 10% ITERM, 95% auto-recharge - eliminates configuration resistors and firmware dependencies. |
| Battery short-circuit protection | 1.7 V detection threshold with 25 mA recovery current - prevents damage from accidental shorted-cell conditions before charging initiates. |
| Reverse discharge protection | Internal blocking path - prevents battery from discharging back into VDD when input is absent, extending standby time. |

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 | 4.20 V charge voltage (vs. 4.10 V); identical OVP (6.5 V), precondition (10%), timer (32 min/6 hr), and status type. | Targets standard 4.2 V Li-ion cells instead of lower-voltage or high-cycle-life variants requiring 4.10 V. | Select when battery chemistry specifies 4.20 V nominal regulation and higher capacity is prioritized over longevity. |
| MCP73114-0NS/MF | 5.8 V OVP threshold (vs. 6.5 V); same 4.20 V regulation, 10% precondition, 32-min/6-hr timers, and Type 1 status. | Designed for systems with tighter input voltage margins where 6.5 V OVP may cause nuisance shutdowns. | Choose when powering from regulated 5 V sources (e.g., USB-PD fixed output) where 5.8 V OVP improves robustness against ripple-induced false trips. |
Compared with MCP73113-06S/MF and MCP73114-0NS/MF, the MCP73113-16SI/MF uniquely combines 4.10 V regulation - beneficial for extended cycle life - with 6.5 V OVP headroom for unregulated adapters, making it optimal for cost-sensitive, space-limited USB-charged consumer electronics where longevity and input ruggedness are both critical.

FAQ
What is the factory-set charge voltage for MCP73113-16SI/MF?
The MCP73113-16SI/MF is factory configured for 4.10 V constant-voltage regulation with ±0.5% accuracy across -5°C to +55°C ambient temperature. This setting targets high-cycle-life Li-ion or Li-polymer cells where reduced termination voltage extends usable battery lifespan compared to standard 4.20 V profiles.
Does MCP73113-16SI/MF require external MOSFETs or current-sense resistors?
No. The MCP73113-16SI/MF integrates a P-channel pass transistor (350 mΩ RDS(on)), current-sense circuitry, reverse discharge protection, and input overvoltage protection. Only one external resistor (RPROG) and two ceramic bypass capacitors (CIN, COUT) are required for full operation.
How does the PROG pin function in MCP73113-16SI/MF?
In MCP73113-16SI/MF, the PROG pin serves dual roles: (1) it sets fast-charge current via resistor-to-VSS (130–1100 mA range), and (2) it acts as an enable/disable input - floating or >200 kΩ impedance places the device in standby mode with zero quiescent current draw from VDD.
What protection features are built into MCP73113-16SI/MF?
The MCP73113-16SI/MF includes integrated input overvoltage protection (6.5 V), undervoltage lockout (4.15 V), thermal regulation (current foldback above ~105°C), thermal shutdown (150°C), battery short-circuit detection (1.7 V), and reverse discharge prevention - all without external components.
Is MCP73113-16SI/MF compatible with standard Li-ion batteries rated for 4.2 V?
Yes, but with design consideration: MCP73113-16SI/MF's 4.10 V regulation is optimized for longer cycle life and lower stress on certain Li-ion chemistries. It remains safe for use with standard 4.2 V-rated cells, though full capacity may not be achieved; verify battery manufacturer's recommended charge voltage before deployment.
