ADM6315-31D3ARTZR7

The ADM6315 is a reliable voltage monitoring device that is suitable for use in most voltage monitoring applications. The ADM6315 is designed to monitor as little as a 1.8% degradation of a power supply voltage. The ADM6315 can monitor all voltages (at 100 mV increments) from 2.5 V to 5 V. Included in this circuit is a debounced manual reset input. RESET can be activated using an ordinary switch (pulling MR（overline） low), a low input from another digital device, or a degradation of the supply voltage. The manual reset function is very useful, especially if the circuit in which the ADM6315 is operating enters into a state that can be detected only by the user. Allowing the user to reset a system manually can reduce the damage or danger that could otherwise be caused by an out of control or locked up system. The ADM6315 is available in a cost efficient and space efficient SOT - 143 package. The ADM6315 is designed to protect the integrity of a system’s operation by ensuring the proper operation of the system during power - up, power - down, and brownout conditions. When the ADM6315 is powered up, the RESET output of the ADM6315 remains low for a period typically equal to the RESET active timeout period. This feature allows adequate time for the system to power up correctly and for the power supply to stabilize before any devices are brought out of reset and allowed to begin executing instructions. Initializing a system in this way provides a more reliable startup
