The MCP73113 is a highly integrated Li-Ion battery charge management controller for use in space-limited and cost-sensitive applications. It features complete linear charge management including input overvoltage protection, pass transistor, current sense, and reverse discharge protection. Additionally, it offers constant current/constant voltage operation with thermal regulation, undervoltage lockout, high accuracy preset voltage regulation, resistor programmable fast charge current, preconditioning of deeply depleted cells, automatic end-of-charge control, automatic recharge, charge status output, and more.
The MCP73113 is a highly integrated single‑cell Li‑Ion/Li‑Polymer battery charge management controller designed for space‑limited, cost‑sensitive applications. It provides constant‑current/constant‑voltage charging, input over‑voltage protection, reverse‑discharge protection, and thermal regulation, with selectable charge‑voltage options and programmable fast‑charge current.
Typical applications include low‑cost portable chargers for MP3 players, digital cameras, Bluetooth headsets, USB chargers and other handheld devices. The device is offered in a 3 × 3 mm DFN‑10 package and includes a PROG pin that doubles as an enable pin for standby operation.
| Input Voltage Range | 4 V – 16 V |
|---|---|
| Operating Supply Voltage | 4.2 V – 6.5 V |
| Fast Charge Current | 60 mA – 1000 mA |
| UVLO Start Threshold | 4.10 V – 4.45 V |
| UVLO Stop Threshold | 4.00 V – 4.15 V |
The absolute maximum input voltage is 18 V.
The PROG pin serves as an enable pin; when it is high‑impedance, the device enters standby mode.
