概要
Description
- Programmable charge current via a resistor (ISET).
- Automatic preconditioning for deeply discharged cells, then constant-current charging, then constant-voltage regulation to about 4.2V.
- Automatic termination when charge current falls below a threshold; automatic recharge when input remains connected.
- Built‑in safety features: overcurrent protection, thermal regulation, and protection against reverse current.
- Designed for USB or other 5V‑like inputs; suitable for compact portable devices.
- The suffix LXEDC#TRPBF indicates the specific package and tape‑and‑reel RoHS packaging.
For exact electrical specs, pinout, and application circuits, refer to the LTC4065 datasheet.
Equivalent
- Microchip MCP73831/MCP73832 (single‑cell Li‑ion chargers with resistor‑set current)
- TI BQ24040 / BQ24075 (USB/standalone Li‑ion chargers)
These offer similar constant‑current/constant‑voltage charging and safety features; verify pinout and regulation specifics for a drop‑in replacement.
Features
- Standalone, single‑cell Li‑Ion/Li‑Pol charger with CC/CV charging
- Fixed 4.2V termination with automatic recharge
- Programmable charge current via external resistor
- Preconditioning for deeply discharged cells
- Battery temperature safety and protection features
- Thermal regulation with current foldback to protect battery and device
- Over‑current, short‑circuit, and reverse‑current protection
- Status indicator via a pin (CHRG/STAT) for charging/complete
- Low quiescent current in standby
- 8‑pin package; Pb‑free, Tape & Reel (TRPBF) shipping
Note: For exact electrical specs (currents, tolerances, input range), refer to the datasheet.
Pinout
- Function: Single-cell Li‑ion/Li‑polymer battery charger controller. Provides constant-current/constant-voltage charging from an input source with charge termination and basic status features (suitable for USB/wall adapter inputs).
Manufacturer
- Company type: Analog Devices is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.
