FEATURES Triple supervisory circuits Supply voltage range of 2.0 V to 5.5 V Pretrimmed threshold options: 1.8 V, 2.5 V, 3.3 V, and 5 V Adjustable 0.6 V and 1.25 V voltage references Maximum supply current of 40 μA 140 ms (minimum) reset timeout RESET valid from VDD ≥ 1.1 V Push-pull RESET and RESET outputs 8-lead, narrow body SOIC package Temperature range: −40°C to +85°C APPLICATIONS Supervising DSPs/microcontrollers Industrial and portable equipment Wireless systems Notebook/desktop computers GENERAL DESCRIPTION The ADM13307 is a triple voltage supervisor designed to monitor up to three voltage levels in DSP and microprocessor- based systems. There are five models available, all of which feature a combina- tion 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. 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 volt- age monitored by the SENSEv pins falls below its associated falling input threshold voltage, VIT−, the RESET output asserts.

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. |
