Product Details

Demonstration circuit 2133A features a simple battery charger circuit using the LTC4079 high-voltage monolithic linear charger. The DC2133 has an input voltage range from 2.7V to 60V and is capable of supplying up to 250mA charge current. The charge voltage is jumperselectable to 4.2V or 8.4V. Charge current is adjustable via the PROG pin and initially programmed for 99mA. In shutdown or when unpowered, LTC4079 consumes only 10nA from the battery.
