Typical Operating Circuit GENERAL DESCRIPTION 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- and space-efficient SOT-143 package. Rev. E Information furnished by Analog Devices is believed to be accurate and reliable.

One feature of the ADM6315 is the RESET opendrain output, which can sink current from sources with a voltage greater than the VCC of the ADM6315 input, making it suitable for use in more diverse applications. MANUAL RESET INPUT The ADM6315 also provides an additional input, MR. This input can be used either as a means for the system operator to reset the system manually via a switch or for a digital circuit to reset the system. The MR input (typically) ignores negative-going pulses that are faster than 100 ns, and it is guaranteed to accept any negativegoing input pulse of a duration greater than or equal to 1 μs. If MR is connected to long cables or is used in a noisy environment, placing a 1 μF decoupling capacitor between the MR input and ground further improves the glitch immunity of the ADM6315. VCC TRIP POINT (MAX) VCC TRIP POINT BENEFITS OF A VERY ACCURATE RESET THRESHOLD Because the ADM6315 series can operate effectively even when there are large degradations of the supply voltages (due to an accurate internal voltage reference circuit), the possibility of a malfunction during a power failure is greatly reduced.

VCC Power-Down/Brownout Timing Diagram RESET DETAILED DESCRIPTION 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 for microprocessor systems. When a brownout condition occurs (assuming VCC is falling at 1 mV/μs), the ADM6315 produces a reset in 35 μs typical. Producing a reset this fast means that the entire system can be reset together before any part of the system’s voltage falls below its recommended operating voltage. This system reset can avoid dangerous and/or erroneous operation of a microprocessorbased system. Figure 11. VCC Power-Up Timing Diagram TRANSIENT IMMUNITY As well as being an accurate reset circuit, the ADM6315 has good immunity from negative-going transients (see Figure 7). Because of this characteristic, the ADM6315 is suitable for use in noisy environments. Figure 7 shows the RESET comparator overdrive (the maximum magnitude of negative-going pulses with respect to the typical reset threshold) vs. the pulse duration without a reset. Rev.
