Linear Charger for Low Voltage Battery BD71631QWZEVK User’s Guide
●Description: This EVK is for evaluating the linear charging IC BD71631QWZ, and charges 4.2V from the 5V input voltage. BD71631QWZ accepts a power supply input rangeof2.9V to 5.5V and generates a charging battery voltage ranging from 2.0V to 4.7V using external resistors.If the charging current is VIN ≥ 4 V, it can be used up to 300 mA under the condition of VIN-VOUT ≥ 1 V and up to 100 mA under the condition of VIN-VOUT ≥ 0.3 V. If 2.9 V ≤ VIN ≤ 5.5 V, it can be used up to 30 mA under the condition of VIN-VOUT ≥ 0.3 V. The charging current can be set with an external resistor. The termination current can be set from 50 μA to 10 mA using external resistors. Additional protection functions include a built-in Fixed 10-hour Safety Timer, UVLO (Under Voltage Lock Out), TSD (Thermal Shutdown Detection),and Battery Over Voltage Protection.
