THP210: Behavior when PD = VS– in Dual Supply Mode

Part Number: THP210
Other Parts Discussed in Thread: THS4130

Tool/software:

Hello,

I am working on designing a circuit that is compatible with both the THS4130 and THP210. We will decide which IC to use based on the results of lab testing. However, I encountered an issue during the simulation phase in PSpice. Since the THP210 model does not include a PD (Power-Down) pin, I am unable to simulate the power-off mode for this device.

Additionally, I’ve noticed that the power-down pin characteristics differ slightly between the two ICs:

For THS4130: “If the PD pin is less than 1.4 V greater than VCC–, then the device is off.”

For THP210: “Power-down disable voltage is (VS+ – 2.0 V).”

Both devices are powered using a ±12 V dual supply. In the case of the THS4130, I successfully switch the device into power-down mode by applying –12 V to the PD pin through a switching circuit.

However, I am unsure whether the same approach will work for the THP210. I am uncertain whether applying –12 V to the PD pin of the THP210 will properly trigger power-down mode.

So my question is:
Under ±12 V dual supply condition, if I apply –12 V to the PD pin of the THP210, will the device enter power-off mode?

Thank you in advance for your responses

Best Regards,
