TS5A23157: For Resistor connect and Disconnect

Balaji Padmanaban

Part Number: TS5A23157

Tool/software:

Hi All,

Am planning to use TS5A23157DGSR for resistor connect and disconnect resistor,

Below is the example of the circuit

The goal is to connect R498 or R499 to COM2 Pin,

The COM2 pin is connected to another IC(ISET) pin which is an ANALOG INPUT to connector External resistor input to set LED current.

Will this logic work, meaning can TS5A23157DGSR connect and disconnect resistor between NC2 to COM2 or NO2 to COM2

To avoid resizing the image, remove the "Dimensions" numbers.

This will work. The switches, when closed, behave like 10 Ω resistors.

Sure.

One more question, the Switches doesn't need any current or voltage on COM1 correct?

It can act as a Dry Relay Contact to Close and Open?

Because the COM1 will not have any voltage on the ISET pin which is connected to it.

Yes; it is a passive switch.
