Overview
WS4054 is a complete single-cell lithium-ion battery CC/CV linear power management IC. Its slim profile and compact package make it ideal for portable applications. Specifically designed to comply with USB power supply specifications. Thanks to the internal MOSFET architecture, no external sense resistors or blocking diodes are required. During high power operation or elevated ambient temperatures, thermal feedback automatically reduces the charge current to limit die temperature.
Applications
- Mobile phones, tablets, MP3 players
- Bluetooth applications
Key features
- Programmable charge current up to 500mA
- No MOSFET, sense resistor, or blocking diode required
- Compact form factor for complete linear charge management of Li-ion batteries
- CC/CV operation with thermal regulation for maximum charging efficiency without risk of overheating
- Single-cell Li-ion battery management via USB interface
- Preset charge voltage: 4.2V ±1%
- Trickle charge threshold voltage: 2.9V
- ESD (HBM) > 7KV
