TL594 - some questions

Other Parts Discussed in Thread: TL594

Hi all

Would you mind if we ask TL594?

<Question1>
How much is the value of DTC pin in case of Vcc=15V?
Is this only offset level?

<Question2>
Is DTC pin output or input?(because of -2uAtyp/-10uAmax).

<Question3>
When the DTC is open, what does the device operate? unstable operation?

Kind regards,

Hi Hirotaka-san,

I have asked one of applications engineers to respond to your questions, this may take another day as they are based in the US and it is a public holiday.

Regards

Peter

Hello Matsumoto-san,

1. I am not sure what you mean by the value of the DTC pin. This pin is an input pin and is used to set the dead time control for the device.

2. This pin is an input, and it works based on how it is described in Section 3.3.1 of the following application note: www.ti.com/.../slva001e.pdf

3. The DTC pin should not be left floating as this can affect operation. It should be grounded if you are not using it to set a dead time larger than 3%.

Best,
Michael
