Part Number: TS5A21366
Hi TI experts,
For current project I'm evaluating using TS5A21366 to isolate the ADC signal from potentiometer to uController.
However I want to know if I can use only one control signal for IN1 & IN2.
Is this possible or is there any internal circuitry that I need to pay attention to?
Externally there is a pull down resistor 10K on the control signal for another PowerFET circuitry control.
Basically I wanted to use single signal to toggle the MOSFET and TS5A21366 if possible.
Tony,
Please refer to this application note Semiconductor and IC package thermal metrics
It is best if you use the RθJA value as a way to compare parts versus using the value as an absolute since the customer’s system PCB design will highly influence this number as stated above.
But if you must have a number using this calculation Tjmax= Ambient Tempmax + Pmax(RθJA) here it is below:
Signal Switch power dissipation and junction temperature calculator.xlsx
The max power for the TS5A21366 can be calculated by
Pmax = (V+max)(I+max) + 2*[(Ino,Inc,Icommax)^2(Ron)]
About 112mW = (5.5 V)(10uA) + 2[(200mA)^2(1.4 Ohm)
Tjmax= Ambient Tempmax + Pmax(RθJA)
Tjmax = (85°C) + (112mW)(253°C/W)
Tjmax = 113.3°C
113.3°C is an approximation of the maximum junction temperature that the device can obtain while operating at its maximum recommended values. The datasheet abs max table states that max storage temperature for the device is 150°C which is well above 113.3°C. This will mean that there is little risk of thermally causing damage while running this part to its maximum recommended values.
Thank you,
Adam
Hi all
Would you mind if we ask TS5A21366 and SN74CB3T3306?
In case of switch OFF, is it possible to regard the value as Hi-z(∞)?
Kind regards,

Hi team,
I'm Matteo, Analog FAE in the graduate program EMEA.
A customer that I'm supporting wants to know the DC behavior of the TS5A21366, doesn't find into the data sheet.
Can we help him?
Many thanks
Matteo

Hello,
Does this device have positive clamping diodes on VIN?
Basically, trying to understand if I can apply 5V to VIN or NO when VCC is 3.3V. I read the footnote that "The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed" but it's still pretty unclear.
Thanks,
Michael

Hello,
I am using the TS5A2066 in my design, but I need high impedance on its outputs when there is no Vcc (device OFF). This device partially provides the input voltage when not powered.
Is it possible with another similar reference?
Thank you
Part Number: SN74CBT3306
Hi
We are using SN74CBT3306PWR in our design just want to know what will happen if pin#8 (VCC) slowly ramp-up from 0V to 5V then whta is the state of o/p from 0V to 4V since BCC operating condition is 4V to 5.5V
Thanks

e2e,
I would like to replace TS5A23166DCUR with T5A21366DCUR. Would you please let me know the pinout, package, and parametric differences between these two devices?
Thank you,
Adam

Hi team,
Here I have customer for IPC application that they want some information about Tj.
There have information about Ta and Tcase , and they want some information for Tj
Thanks for your help.
