Overview
a Open-Drain Microprocessor Supervisory Circuit in 4-Lead SOT-143 ADM6315 FUNCTIONAL BLOCK DIAGRAM GND VREF VCC FEATURES Superior Upgrade for MAX6315 Specified Over Temperature Low Power Consumption (5 ␮ A Typ) Precision Voltage Monitor of Voltages from 2.
5 V to 5 V at 100 mV Increments Reset Assertion Down to VCC > 1 V Built-In Manual Reset Pin Compatible with the ADM811 APPLICATIONS Microprocessor Systems Controllers Intelligent Instruments Automotive Systems Safety Systems Portable Instruments ADM6315 RESET RESET CIRCUITRY DEBOUNCE MR VCC GENERAL DESCRIPTION SYSTEM POWER 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.
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.
