BQ2057WSNTR Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the power traces short and wide, and use a common ground point for the IC and the battery.
-
Use a high-precision resistor divider network to scale the battery voltage, and calibrate the device using the CAL pin. Also, ensure that the battery voltage is within the recommended range of 2.5V to 4.5V.
-
The BQ2057WSNTR can handle up to 2A of continuous current, but it's recommended to limit the current to 1.5A for optimal performance and to prevent overheating.
-
Use the OVP pin to detect overcharge conditions and disconnect the charger using an external FET or relay. The OVP threshold is set to 4.2V, but can be adjusted using an external resistor divider network.
-
Yes, the BQ2057WSNTR is designed to work with lithium-ion polymer batteries. However, ensure that the battery's protection circuit is disabled or configured to work with the BQ2057WSNTR's charging algorithm.
