Product Description
Product Overview
The LN4913 is a low-power, high-sensitivity CMOS Hall-effect sensor IC designed for battery-operated devices. It functions as an On/Off switch, ideal for applications like cellular flip-phones and notebook PCs. The device features precise magnetic switching points, high temperature stability, and an omnipolar switching behavior, allowing activation by either magnetic pole. Its micro-power design and onboard clock scheme significantly reduce average operating current by utilizing an operate and standby phase, with the output stage latched in standby to minimize current consumption to a few microamperes.
