Description
Equivalent
1. Microchip MCP73831: A highly integrated Li-Ion/Li-Polymer linear charger.
2. Linear Technology LT1510: A full-featured, constant-current/constant-voltage battery charger.
3. STMicroelectronics STC4054: A standalone linear Li-Ion battery charger.
4. Analog Devices ADP5063: A high-performance linear battery charger.
Ensure compatibility in terms of voltage, current, and other specifications when considering substitutes.
Features
1. Charge Termination: It uses a voltage-based technique to terminate charging, ensuring optimal battery performance and safety.
2. Precharge Conditioning: The IC includes a precharge conditioning mode that helps revive deeply discharged batteries by applying a low-level current.
3. Charge Status Indicator: It provides an easy-to-use charge status indicator to show whether the battery is charging, fully charged, or faulty.
4. Under-voltage Lockout (UVLO): This feature prevents battery damage by ensuring the battery is not charged if the supply voltage is too low.
5. Automatic Recharge: Once the battery is fully charged and then partially discharged, the IC automatically restarts the charging process.
6. Small Package: It is available in a compact, surface-mount package, suitable for space-constrained applications.
These features make the BQ2057WSNTR an ideal choice for portable and battery-operated devices, where efficient and safe battery charging is crucial.
Pinout
1. VCC (Pin 1): This is the input supply voltage pin. It is where the input voltage is applied to power the IC.
2. BAT (Pin 2): This pin connects to the positive terminal of the battery being charged. It serves as the output pin to provide charging current to the battery.
3. ISET (Pin 3): This pin is used to program the charging current. A resistor connected to this pin sets the desired charge current value.
4. GND (Pin 4): The ground pin serves as the common ground reference for the IC.
5. STAT (Pin 5): This is the status pin, which indicates the charging status through an LED or other signaling method. It can show whether the battery is charging, fully charged, or if there is a fault condition.
The BQ2057WSNTR is designed for simple and efficient battery charging with minimal external components.
