Additional preview pages of the MC3425 datasheet.

The MC3425 is a power supply supervisory circuit containing all the necessary functions required to monitor over and undervoltage fault conditions.

The block diagram is shown below in Figure 15.

tDLY) is based on the constant current source, IDLY(source), charging the external delay capacitor (CDLY) to 2.5 V. Vref CDLY 2.5 CDLY = 12500 CDLY tDLY = = IDLY(source) 200 µA Figure 5 provides CDLY values for a wide range of time delays. The Delay pins are pulled low when the respective input comparator’s.
