The ADM6315 is designed to monitor as little as a 1.8% degradation of a power supply voltage. Voltages that can be monitored by the ADM6315 are 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 low), by a low input from another digital device or by 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 only be detected by the user. Allowing the user to manually reset a system can reduce the damage or danger that could be otherwise caused by an out of control or locked-up system. The ADM6315 comes in a cost and space efficient SOT-143 package. MR...
