AME2056
n General Description
The AME2056 is constant-current/constant-voltage lin-
ear charger IC for single cell lithium-ion batteries. The
battery charge termination voltage is fixed at 4.2V, the
charge current can be programmed an external resistor
up to 1000mA(Max.). In the trickle charge mode, the
trickle charge voltage is 2.9V that automatically termi-
nates the charge cycle when the charge current drops to
1/10 the programmed value after the final float voltage is
reached. Other features includes Thermal Shutdown, Soft-
start Function, Battery temperature detector, under-volt-
age lockout, automatic recharge and two Status indica-
tion for Charge Status, no battery and battery failure indi-
cators.
