MAX17015B Datasheet PDF - Maxim Integrated

●General Description

●The MAX17005B/MAX17006B/MAX17015B are high-frequency multichemistry battery chargers. These circuits

●feature a new high-frequency current-mode architecturethat significantly reduces component size and cost

●.

●The charger uses a high-side MOSFET with n-channel synchronous rectifier. Widely adjustable charge current,

●charge voltage, and input current limit simplify the construction of highly accurate and efficient chargers.
