MAX1661-MAX1663中文资料美信数据手册PDF规格书

General Description

The MAX1661/MAX1662/MAX1663 serial-to-parallel/parallel-to-serial converters are intended to control external power MOSFETs in power-plane switching applications. These small, low-cost devices can be used on a system motherboard to control point-of-load switching from a 2-wire SMBus™ serial interface. Each device has three high voltage open-drain outputs that double as TTL-level logic inputs, giving them bidirectional capabilities. The I/O pins can withstand +28V, so they can control battery voltage distribution switches in notebook computers.
