Part Number: ISO5852S-EP

Hi Team,

May I know what is the current consumption by the RST pin of ISO5852S-EP?

Thanks

Hi,

In the datasheet the leakage current for the RST pin is specified by I_IL. Unfortunately, we do not have a specification for the maximum current consumption.

Best,

Nancy

Hi,

In my design, We have 4 ISO5852S-EP chips. The output of AND gate is connected to RST pins of all 4 chips. So i wanted to know whether the AND gate is able to drive the RST pins of all four ICs. Is there any other way to verify the same?

Hi Santhosh,

Since the RST pin is a high-impedance pin, the voltage level of the output of the AND gate is the determining factor here, not the current. As long as the AND output HI voltage is greater than or equal to VCC*0.7, this will properly drive the RST pins.

Best,

Nancy

Hi Hidalgo,

If AND output is HI, RST doesnt occur, So LO at the output of AND gate will drive the RST pins of the 4 chips. Hope my assumption is correct

Hi Santhosh,

Yes, your understanding is correct.
