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. Available with different parts to cover products employing slide switch (PT8A2707/10/17), tact switch (PT8A2708/09/11/12/18/19) input to control motor ON/OFF. Two-step motor-speed control (70%, 100%) is also available in PT8A2708/2711/2718. Very low standby current of typical 20A. Products could typically work in standby-mode for a few months, depends on battery capacity. Technology Highlights Employing 5 major charging states: cool-down / pre-charge / fast charge / trickle charge / stop charge, taking the best care for different battery conditions, especially for aged or dry batteries Excellent battery protection and full-charge detection schemes Negative delta voltage detection (-ΔV) with precision of +/-1mV step Maximum battery voltage detection to turn to maintenance Rate of change of temperature detection (dT/dt) best for NiMH batteries full-charge termination (use with NTC) Abnormal high battery temperature (55C) detection to stop charging (use with NTC) Flexible fast charge time-out setting (30mins/60mins/90mins/150mins) Fuel-gauge counter takes into account the battery self-discharge compensation based on time. Provide excellent battery over-discharge protection through auto-stop motor at once (<0.2s) when discharging current is higher than preset limit value for 3sec (3 limit values selectable externally) battery pack voltage is lower than No-Power value (adjustable externally) NTC measures battery pack temperature higher than preset high-temp value(adjustable externally) Key delay to reject multiple inputs at Tact switch (about 0.125s ignorance). Internal voltage regulator provides better rejection to interference. Integrated DC/DC step-down controller to regulate constant charging currents at different charging Available with 24-pin SOIC and SSOP lead-free package |
