PT6605DW 3~5 Cell Series Li-ion/Polymer Battery Detection IC
■The PT6605DW battery detection IC is designed for protecting 3~5 cell series lithium- ion/polymer battery from being damaged or overall lifetime degrading due to cell over- charge, over-discharge or over temperature condition. Its CO indicates over-charge, over and low-temperature event when charging, while DO indicates over-discharge, over and low-temperature during discharging.
■The small TSSOP14 package and minimum required external components make it easy to be integrated into the limited space in battery pack.
■The accurate ±25mV overcharging detection voltage ensures safety and fully battery capacity charging.
■The low power design only consumes insignificant current in storage stage.
