MicroPower™ Microprocessor Reset Circuit

Supply Voltage Transient Behavior

In some cases, fast negative transients of short

duration can appear on the V_CCpower supply. The

Applications Information

Reset Output Options

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 versus 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 (i.e., typically a transient

of 100mV below the reset threshold would have to

present for more than 50µs to cause a reset).

Immunity can be increased by the addition of a small

bypass capacitor of 0.1µF connected as closely to

the V_CCpin as possible.

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 3). In the

event of a power down or brown-out condition, the

reset signal remains valid until the V_CCdrops below

1.2V. To ensure validity down to ground, an exter-

nal 100kΩ resistor should be connected between

the RESET output and GND.
