Product Overview

BD71631QWZ evaluation board is for evaluating the linear charging IC BD71631QWZ, and charges 4.2V from the 5V input voltage. BD71631QWZ accepts a power supply input range of 2.9V 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 >= 4V, it can be used up to 300mA under the condition of VIN-VOUT >= 1V and up to 100mA under the condition of VIN-VOUT >= 0.3V. If 2.9V <= VIN <= 5.5V, it can be used up to 30mA under the condition of VIN-VOUT >= 0.3V. The charging current can be set with an external resistor. The termination current can be set from 50µA to 10mA 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.
  • Used in low voltage battery products and li-ion 1cell battery products
