MAX17005ETP集成电路（IC）的电池充电器规格书PDF中文资料

General Description

The MAX17005/MAX17006/MAX17015 are high-frequency multichemistry battery chargers. These circuits feature a new high-frequency current-mode architecture that 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.
