6 / 8 page  Applications Information Reset Output Options The AAT3524 has an active low open drain output and the AAT3520/2 have a push-pull output. The AAT3524 may be used in multiple voltage systems, with an external pull-up resistor. This allows the AAT3524 to interface to microprocessors with high- er supply voltages up to 5.5V (Figure 2). In the event of a power down or brown-out condition the reset signal remains valid until the V CC drops below 1.2V. To ensure validity down to ground an external 100k Ω resistor should be connected between the RESET output and GND. Supply Voltage Transient Behavior In some cases fast negative transients of short dura- tion can appear on the V CC power supply. The AAT3520 series devices provide some immunity to line transients which can generate invalid reset puls- es. Figure 1 shows typical behavior to short duration pulses verses RESET comparator overdrive. As shown in the Maximum Transient Duration vs. Reset Threshold Overdrive graph, when the transient volt- age becomes larger, the time allowed before assert- ing a reset becomes shorter. e.g. typically a transient of 100mV below the reset threshold would have to present for more than 50 µs to cause a reset. Immunity can be increased by the addition of a small by-pass capacitor of 0.1µF connected as close to the V CC pin as possible.
