To Load

VDT = Vdd*R2 / (R1+R2). Vdd is output voltage of Microcontroller.

The operating range that allows a VDT range of 1.2~3.3V.

When pulled lower than VDT [Typ. 0.5V] the device is shutdown.

Care must be taken to avoid below threshold spikes on pin 3 that can cause undesired shut down of the IC.

For this reason the connection of the components between pin 3 and ground has to be as short as possible.

And a capacitor (Typ 0 .02 uF )between pin3 and COM can prevent this spike. This pin can not be left

floating for the same reason.
