MAX1703ESE-T - Brand New Maxim Integrated IC Chips
-
Description
The MAX1703ESE-T is an integrated multi chemistry battery charger IC that simplifies the construction of accurate and efficient chargers. It provides programmable charge current, charge voltage, input current limit, relearn voltage, and digital readback of the IINP voltage. The MAX1703ESE-T utilizes a charge pump to control the adapter selection n-channel MOSFETs when the adapter is present. It can provide up to 7A of charge current to 2, 3, or 4 lithium-ion (Li+) cells in series. The MAX1703ESE-T operates with a switching frequency of 1.2MHz and is available in a 4mm x 4mm x 0.75mm 24-pin QFN package.
