Description
The STM11 power control switch contains a low on-resistance P-channel power MOSFET
driven by built-in control circuitry. Its low on-resistance allows switching of continuous
current up to 3.7 A. The low current consumption of 2 µA and small DFN package make this
device a perfect solution for mobile and portable applications.
The device is equipped with 3 inputs to detect a power request and provide switch control
between the battery and the application (see
monitoring with hysteresis to prevent circuit wake-up until battery voltage is at sufficient
level. The threshold voltage level is optimized for single cell Li-Ion or Li-Polymer batteries.
