its compact package with minimum external components makes the portable eta4054 ideal for application. No external inductive resistance or blocking diode is necessary for the eta4054.

Eta4054, can be used for electronic cigarette small package dfn3 * 3, charging current 800mA

the built-in thermal feedback mechanism adjusts the charging current and controls the temperature of the mold during high power operation or rising.
eta4054 has the following advantages The function of pre charging trickle charging deep discharge battery.
the fast charging current can be programmed externally.
the resistance.
CV regulation mode is automatically enabled once.
the battery charging curve reaches a constant voltage.
part.
the output current then decays.
finally.
once the charging current drops to 1 / 10th of the program value.
eta4054 keeps monitoring the battery voltage.
and enables a new charging curve Eta4054 has a variety of packages.
