MAX17005AETP+集成電路（IC）的電池充電器規(guī)格書PDF中文資料

General Description

The MAX17005A/MAX17006A/MAX17015A 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.
