APPLICATION INFORMATION

To avoid unnecessary resets caused by fast power supply

transients, the ADM6384 is equipped with glitch rejection

circuitry. The typical performance characteristic in

Both active-low and active-high reset outputs are guaranteed to

resistor with push-pull configured reset outputs, valid outputs

for V

The curves show combinations of transient magnitude and

duration for which a reset is not generated for 4.63 V and

2.93 V reset threshold parts. For example, with the 2.93 V

threshold, a transient that goes 100 mV below the threshold

and lasts 8 μs typically does not cause a reset, but if the transient

is any bigger in magnitude or duration, a reset is generated. An

optional 0.1 μF bypass capacitor mounted close to V

output, a resistor connected between RESET and ground pulls

the output low when it is unable to sink current. A large

resistance such as 100 kΩ should be used so that it does not
