Power Charger 9v 1a 9w Wall Charger

Power Charger 9v 1a 9w Wall Charger  

• The lithium battery charger can automatically detect the charging power supply, and automatically turn off when there is no power supply to reduce battery leakage. After starting the quick charging, open the external P-type FET, and enter the pulse charging mode when the battery voltage is detected to reach the set threshold. The opening time of P-channel FET will be shorter and shorter, and at the end of charging, the LED indicator light will flash by 12% cycle. When the charging power supply and the battery are within the normal operating temperature range, the battery insertion will start the one-charge process. Charging ends when the average pulse charging current reaches 1% of the fast charging current, or when the time exceeds the preset charging time on the chip.
  
  
• Lithium battery charger is a charger specially designed to charge lithium ion battery. Lithium ion battery has a high requirement on charger and needs protection circuit. Therefore, lithium battery charger usually has a high control precision and can charge lithium ion battery at constant current and constant voltage.
