◆ Highly integrated, very few peripheral components;nup嘉泰姆
◆ Linear charging mode with built-in 0.7A (typical value);nup嘉泰姆
◆ Trickle/constant current/constant voltage three-stage charging, constant voltage 4.20V (typical value), support for 0V battery charging;nup嘉泰姆
◆ Built-in charging can automatically reduce the charging current according to the temperature rise, 130 degrees began to drop, the minimum can be reduced to 0;nup嘉泰姆
The charging input has anti-back irrigation function, do not need anti-back irrigation diode;nup嘉泰姆
◆ The boost uses a synchronous rectification circuit, with an efficiency of up to 91%, low heat generation, fixed 5.1V (typical value) output, and no external resistance setting is required;nup嘉泰姆
◆ The output current is 0.7A (typical value when the battery is 3.6V), with constant power output function, complete overcurrent and short circuit protection; ◆ Load insertion automatically starts boosting, load removal automatically sleeps;nup嘉泰姆
◆ Battery low-voltage reminder function;nup嘉泰姆
◆ Single lamp charging and discharging indication: the indicator LD1 flashes during charging, and the indication is on after full charge; The indicator LD1 lights up during discharge. When the battery voltage is less than 3.2V (typical value), the indicator LD1 flashes until the 2.95V undervoltage shutdown indicator LD1 goes out.nup嘉泰姆
