LTC4054 TLC4054 LTH7 SOT23-5 Standalone Linear Li-Ion Battery Charger

Product Description: LTC4054 TLC4054 LTH7 SOT23-5 Standalone Linear Li-Ion Battery Charger
The LTC4054 TLC4054 LTH7 SOT23-5 is a standalone linear lithium-ion battery charger designed for single-cell batteries. It operates in a constant-current/constant-voltage mode, with a preset charge voltage of 4.2V and a programmable charge current up to 800mA. The charger features thermal regulation to prevent overheating and includes an internal MOSFET, eliminating the need for external sense resistors or blocking diodes. It is suitable for charging batteries directly from a USB port, making it ideal for portable devices, cellular telephones, PDAs, MP3 players, and Bluetooth applications.

Features:

• Charge Voltage: Fixed at 4.2V with ±1% accuracy.
• Charge Current: Programmable up to 800mA using an external resistor.
• Thermal Regulation: Prevents overheating during high power operations.
• Package Type: SOT23-5 for compact designs.
• No External Components Required: No MOSFET, sense resistor, or blocking diode needed.
• Automatic Recharge: Automatically recharges when the battery voltage drops.
• Charge Status Output: Indicates charge completion and input voltage presence.
• Low Power Consumption: Enters low current state when input supply is removed.

Application:
This charger is commonly used in portable electronics, cellular devices, PDAs, MP3 players, and Bluetooth applications where efficient and compact battery charging is required.

Package Included:
1 x LTC4054 TLC4054 LTH7 SOT23-5 Standalone Linear Li-Ion Battery Charger
