Overview
CN3761 is a PWM buck-mode single-cell lithium battery charge management IC that independently manages single-cell lithium battery charging. It features a compact package, minimal external components, and ease of use. CN3761 supports trickle, constant current, and constant voltage charging modes, making it well-suited for lithium battery charge management. In constant voltage mode, CN3761 regulates the battery voltage to 4.2V, which can be adjusted upward via an external resistor; in constant current mode, the charge current is set through an external resistor.
Applications
- Power banks
- Handheld devices
- Backup battery applications
- Portable industrial and medical instruments
- Power tools
- Standalone battery chargers
Key features
- Trickle charging at 17.5% of the set constant-current charge current for deeply discharged lithium batteries when battery voltage falls below 66.5% (typical) of the constant-voltage charge voltage
- In the constant-voltage charging phase, charge current tapers gradually; charging terminates when current drops to 16% of the constant-current charge current
- In the charge termination state, a new charge cycle starts automatically if battery voltage drops to 95.5% of the constant-voltage charge voltage
- Automatically enters sleep mode when input power is lost or input voltage falls below battery voltage
- Additional features include input undervoltage lockout, battery overvoltage protection, and charge status indication
- 10-pin SSOP package
