Description

Conditions of application

Vref

User external power supply

3.3V~48V

R

User external pull-up resistor

R>Vref/0.02  (0,02 is  the maximum value of DO chip drive current)

R(The resistor package tolerates power)>Idrv²*R(Idrv = Vref/R)

Vout

When the output logic is high,Vout = Vref

When the output logic is low,Vout = 0

Vout is used for IO ports of external devices

The external power supply is forbidden to connect directly to the Vout, otherwise it causes the Vout port to start passive protection, resulting in abnormal IO signal.

DO Usage#


Description

Vref

Voltage to be supplied externally at the user side.

Vout

When the output is set, the voltage difference between and GND is equal to Vref.

When no output is set, the voltage difference between and GND is 0.

It is forbidden that the power supply is directly connected to the Vout, otherwise it will cause damage to the device.
