Working Principle of S-80849CLNB-B7AT2G

S-80849CLNB-B7AT2G is a CMOS voltage detector which monitors the power input in the circuit. It is made up of a comparator that compares the input voltage to an internal voltage reference. It also contains a digital circuitry to detect over-voltage/under-voltage conditions. When the voltage is not within the specified range, then the supervisor will reset the circuit and set the output pin to low. When the voltage within the safe range, the digital circuitry will reset itself after a pre-programmed time-out period.

The device is designed to provide a reset at power up, and also during a brown-out condition and under-voltage fault. It has a wide operating voltage range of 2.4V to 6V, which makes it suitable for multiple applications. The internal voltage reference is 2.5V, which allows the device to detect voltage variations up to 5.8V, and has a low active current consumption of 1.8uA.

The S-80849CLNB-B7AT2G is an ideal solution for system monitoring and protection. It helps users create a secure, reliable and cost effective system by providing an extra layer of protection and monitoring of the power input.
