Description
Introduction to CL4056H
CL4056H is a single-cell lithium-ion battery charging IC designed for portable devices. It features a linear charging circuit with constant current and constant voltage (CC/CV) control, ensuring safe and efficient charging. Key specifications include:
- Input Voltage: 4.5V–6V (USB-compatible).
- Charging Current: Up to 1A (adjustable via external resistor).
- Termination: Auto-cutoff at full charge (4.2V ±1%).
- Protections: Overvoltage, overcurrent, and thermal shutdown.
Compact and cost-effective, it integrates reverse polarity protection and low standby current, making it ideal for space-constrained applications like wearables and IoT devices.
