The PT8A2707-12/2717-19 integrates charger controller and fuel-gauge into a single-chip. It detects full-charge through -V, dT/dt, safety-timer and maximum battery voltage, and learns the battery capacity from each charging/discharging cycle. Since PT8A2707-12/2717-19 measures charge/discharge current to account for the battery capacity in/out respectively,.
2-3 cells, NiCd or NiMH 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 volt.
