Overview
The STM6717SJWY6F is a dual/triple ultra-low voltage supervisor produced by STMicroelectronics. This device is part of a family of low-voltage/low-supply current processor supervisors designed to monitor two or three system power supply voltages. It is particularly suited for applications such as set-top boxes (STBs), portable battery-powered systems, networking, and communication systems. The device features a push-button-type manual reset input and is available in standard 5-pin or 6-pin SOT23 packages.
