PT6111
PT6111 is Analog Front End manufactured by Powtech.
GENERAL 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 Li Fe PO4 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. All output voltages are alternatively selected by the co-working MCU and digitized by the ADC within that MCU. The integrated battery balance circuitry in the PT6111 provides a shunt current of 50m A without the need of any external transistors. The chip also includes important Features such as an integrated LDO which power for an external MCU, charge and discharge power MOSFETs driver PT6111 works together with an MCU performs battery safety protections against battery over-voltage, under-voltage and cell balancing. PT6111 is available in QFN-24(4x4) package.
