Smart LCD Battery Charger USB Solar Panels Power Adapter Input For 18650 Lithium 3.7V 4.2V CN3063 | Электроника

18650 Lithium Battery Charger
Suitable for battery nominal voltage 3.7V, limited voltage 4.2V lithium battery
Can use computer USB, solar panels, power adapter as input power
Features:
The circuit adopts CN3063 solar charge management chip for lithium battery
Internal 8-bit analog-to-digital conversion circuit that automatically adjusts the charge current based on the current output capability of the input voltage source
Input voltage range: 4.4V to 6V
Constant voltage charging voltage 4.2V, in order to activate the deep discharge of the battery and reduce power consumption, the use of trickle charge mode when the battery voltage is low, continuous constant current charging current up to 500mA
Constant-current/constant-voltage/constant-temperature mode charging can not only maximize the charge current, but also prevent the chip from overheating. When the input voltage is lost, it automatically enters a low-power sleep mode. At this time, the current consumption of the battery is less than 3 microamperes. .
Other features include low input voltage latch, automatic recharging,
The state of charge and the state of charge are both indicating output: the red light charge state; the green light charge end state; the red light flashes, the green light is always on The battery is not connected properly.
Input voltage: 5V Input method: DC 3.5mm Core 1.3mm (inside negative)
Input and output can not be reversed
