PT8A2717
Features
- 2-3 cells, Ni Cd or Ni MH battery fast-charger controller for battery-embedded devices
- Precise 7-bit fuel-gauge-counter measures charging and discharging current through battery pack. Make it possible to accurately indicate battery capacity through LCD (PT8A2707-09/2717-19) or LEDs (PT8A2710-12).
- Integrated with a DC/DC step-down controller make it possible for customers to manufacture just one
PCB module that can:
- Cover different product models that requires different charging current/speed by changing only one resistor;
- Work with different kinds of AC/DC adapters with wide input voltage ranges.
- Motor also can work in both corded or cordless conditions. When motor is used in cord-mode, the charging current to battery is regulated at a maximum value of 1/10 of the fast-charging current. The battery is just like being slowly-charged and prevented from being exposed to a prolonged high-current charging profile.
- Provide excellent charge and discharge protections.
