HB6295 is an integrated 2/3/4-cell Li-ion/Li polymer switch-mode charge management device, targeted at a wide range of portable applications. HB6295 offers integrated power FET, high-accuracy current and voltage regulation, charge preconditioning, charge status, and charge termination, in a small TSSOP24 package. HB6295 charges the battary in three phase: preconditioning, constant current(CC), and constant voltage(CV). The charge current is programmable with an external resistor up to 4.0A. HB6298A features cycle-by-cycle current limit, charge current thermal foldback and short circuit protection to guarantee safe operation. Additional features include NTC thermistor interface to monitor the battery temperature.
