GENERAL DESCRIPTION The ADM13307 is a triple voltage supervisor designed to monitor up to three voltage levels in DSP and microprocessorbased systems. OSCILLATOR 06923-002 Supervising DSPs/microcontrollers Industrial and portable equipment Wireless systems Notebook/desktop computers RESET LOGIC + TIMER R2 ADM13307-4 ADM13307-5 VDD 14kΩ The ADM13307-18, ADM13307-25, and ADM13307-33 models have two internally fixed thresholds and one externally programmable threshold via a resistor string. The ADM13307-4 and ADM13307-5 offer one internally fixed threshold and two externally programmable thresholds. See the Ordering Guide for a list of all available options. During power-up, RESET is asserted when the supply voltage exceeds 1.1 V. The device then monitors the SENSEv input pins and holds the RESET output low as long as the SENSEv pins remain below the rising threshold voltage, VIT+. Once the supplies monitored at the SENSEv inputs rise above their associated thresholds, the reset signal remains low for the reset timeout period before deasserting. Subsequently, if a voltage monitored by the SENSEv pins falls below its associated falling input threshold voltage, VIT−, the RESET output asserts. MR RESET SENSE1 R1 RESET LOGIC + TIMER R2 GND RESET SENSE2 0.6V OSCILLATOR SENSE3 06923-001 There are five models available, all of which feature a combination of internally pretrimmed undervoltage threshold options for monitoring 1.8 V, 2.5 V, 3.3 V, and 5 V supplies. There are also two adjustable input options with undervoltage thresholds of either 0.6 V or 1.25 V. Figure 2. The ADM13307 features both an active high RESET and an active low RESET output. The manual reset input of the ADM13307 can be used to initiate a reset by means of an external push button or logic signal. The ADM13307 is available in an 8-lead narrow body SOIC package. The device operates over the extended industrial temperature range of −40°C to +85°C. Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable.

There are five models available, all of which feature a combination of internally pretrimmed undervoltage threshold options for monitoring 1.8 V, 2.5 V, 3.3 V, and 5 V supplies. There are also adjustable input options with threshold voltages of either 0.6 V or 1.25 V. ADM13307-18, ADM13307-25, and ADM13307-33 models have two internally fixed thresholds and one externally programmable threshold, via a resistor string, while the ADM13307-4 and ADM13307-5 offer one internally fixed threshold and two externally programmable thresholds via a resistor string. See the Ordering Guide for a list of all available options. RESET OUTPUT The reset outputs are guaranteed to be in the correct state for VDD down to 1.1 V. During power up, RESET is asserted when the supply voltage becomes greater than 1.1 V. Once the supplies monitored at the SENSEv pins rise above their associated threshold level, the RESET signal remains low for the reset timeout period before deasserting. Subsequently, if a supply monitored by the SENSEv pins falls below its associated threshold, the RESET output reasserts. SENSEv V(NOM) VIT– t RESET INPUT CONFIGURATION The SENSEv inputs are resistant to short power supply glitches. Do not allow unused SENSEv inputs to float or to be grounded, instead connect it to a supply voltage greater than its specified threshold voltage. Typically, the threshold voltage at an adjustable SENSEv input is either 0.6 V or 1.25 V. Refer to the Ordering Guide for details. For example, to monitor a voltage greater than 1.25 V, connect a resistor divider network to the device as depicted in Figure 13, where, R1 + R2 ⎞ V MONITERED = 1.25 V⎛⎜ ⎟ ⎝ R2 ⎠ t 0 td td Figure 14. Reset Timing Diagram The ADM13307 features both an active-low push-pull RESET output and active-high push-pull RESET output. MANUAL RESET (MR) The ADM13307 features a manual reset input, which when driven low, asserts the reset output, as shown in Figure 15. When MR transitions from low to high, the reset remains asserted for the duration of the reset active timeout period before deasserting. An external push-button switch can be connected between MR and ground to allow the user to generate a reset. MR 1 MONITORED VOLTAGE R1 t 0 R2 RESET t 0 Figure 13.
