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 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.APPLICATIONS Microprocessor systems Controllers Intelligent instruments Automotive systems Safety systems Portable instruments

The ADM6384 is a supervisory circuit that monitors power supply voltage levels in microprocessor-based systems. A power-on reset signal is generated when the supply voltage rises to a presetthreshold level. The debounced manual reset input of the ADM6384 can be used to initiate a reset by means of an external push button or logic signal.The device is available in a choice of 31 reset threshold options, from 1.58 V to 5.0 V. The minimum reset timeout periods are1 ms, 20 ms, 140 ms, and 1120 ms.The ADM6384 is available in a 4-lead SC70 package and typically consumes only 7 μA, making it suitable for use in low power, portable applications.Applications Microprocessor systems Computers Controllers Intelligent instruments Portable equipment

The ADM6711 / ADM6713 are reset generator circuits suitable for use in microprocessor-based systems. They provide a reset signal on power-up, power-down, and whenever the supply voltage falls below a preset threshold. In addition, both parts have a debounced manual reset input so that a reset signal can also be initiated with an external switch or logic signal.With six different reset threshold options available ranging from 2.32 V to 4.63 V, the ADM6711 / ADM6713 are suitable for monitoring 2.5 V, 3 V, 3.3 V, and 5 V supplies. A reset timeout of at least 140 ms occurs when VCC rises above the threshold. This gives the supply voltage time to stabilize before the microprocessor starts up.The ADM6711 has a push-pull output, so no additional external components are needed. The ADM6713 open-drain output requires an external pull-up resistor that can be connected to a voltage higher than VCC, if desired.The parts are highly reliable with accurate voltage references and immunity to fast, negative-going transients on VCC. Low current consumption and space-efficient, 4-lead SC70 packaging make the ADM6711 / ADM6713 ideal for use in low power portable applications.APPLICATIONS Microprocessor systems Computers Controllers Intelligent instruments Automotive systems

Instead, an active high resetoutput (RESET) is available as well as the active low reset output(RESET).
