DDESCRIPTION
HM4208 is a high-precision single-cell lithium battery charging and discharging control Control circuit, which integrates high-precision over-voltage charging protection, over-voltage discharge protection, Overcurrent discharge protection and other functions. HM4208 includes a single-cell lithium-ion battery Constant current/constant voltage linear charger with anti-reverse charging circuit inside, no need for external Part isolation diode. Thermal feedback can automatically adjust the charging current to Therefore, the chip temperature can be limited under high-power operation or high ambient temperature conditions. system. The product integrates all resistance-capacitance (RC) devices, as well as charging and discharging The built-in electric control MOSFET makes it unnecessary for any external devices.
