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. 0.02µF )between pin3 and COM can prevent this spike. This pin can not be left
floating for the same reason.
