GENERAL DESCRIPTION The ADM6305/ADM6306 are dual voltage supervisors designed to 1.23 V, while in the case of ADM6305D3ARJZ1-RL7 model, it is monitor two supplies and provide a reset signal to DSP- and 0.4 V. The V input of the ADM6305 is not a monitored input. CC microprocessor-based systems. Low supply current and a small The ADM6306 has one adjustable undervoltage reset input, form factor make these devices suitable for portable and battery RST IN, which features a choice of reset threshold, 0.4 V or operated applications. 1.23 V (see the Ordering Guide for more information). The If a monitored power supply voltage falls below the minimum ADM6306 incorporates a variety of internally pretrimmed VCC voltage threshold, a single active low output asserts triggering a undervoltage threshold options for monitoring supply voltages system reset. After all voltages rise above the selected threshold in increments between 2.5 V and 5 V. The ADM6306 also level, the reset signal remains low for the reset timeout period. includes a manual reset input. Not all options are released for Four reset timeout options are available. sale as standard models. See the Ordering Guide for details. The ADM6305 monitors two supplies via two adjustable RESET The ADM6305/ADM6306 output remains valid as long resistor-programmable undervoltage reset inputs. Both RST as V exceeds 0.9 V. CC IN1 and RST IN2 have a reset threshold of either 0.4 V or The ADM6305/ADM6306 are available in a 5-lead SOT-23 1.23 V depending on the particular model that is, the RST IN1 package. These devices are specified over the temperature range and RST IN2 threshold of the ADM6305D3ARJZ-RL7 model is of 40C to +125C. Rev.
