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. |
