Main characteristics of voltage detector : how to read SPEC - detect voltage / release voltage / hysteresis width

Here explains how to read main characteristics / SPEC of voltage detector.

Detect voltage

The detect voltage means the voltage you want to output a reset signal.
For a general voltage detector, the detect voltage is set in the IC. On the data sheet, setting value of detect voltage and accuracy degree of detect voltage are described.

Release voltage / hysteresis width

The release voltage means the voltage that enters release status because the monitoring voltage increases after entering detection status.
For a general voltage detector, voltage difference (hysteresis width) is set in between detect voltage and release voltage.
On data sheets of many products, the release voltage is not described as voltage value, but it should be calculated from detect voltage and hysteresis width.

Release voltage = detect voltage + hysteresis width
