PT6111 Description
PT6111 is a highly integrated battery charge/discharge and balancing management analog front end which support 3 to 7 cells serially connected Li-ion, Li-polymer or 3 to 8 cells serially LiFePO4 battery pack. It is applicable in cordless electrical tools, vacuum cleaner or other multi-cell battery powered systems. PT6111 use a high precision amplifier to buffer each battery cell voltage to an analog output pin.
