TPS2H160-Q1: How much energy can handle the high side switch?

ArTzy

Part Number: TPS2H160-Q1

Hi Experts,

Seeking your assistance please:

We are using this High Side to drive inductive loads. During load turn off condition there will be demagnetization energy which will appear across the switch. In the datasheet (p17), there is an equation to calculate the energy:

Question:
How much energy can handle the high side switch? There is no information found in the datasheet.

Thank you.

Hi Archie,

You can find the abs max value with the testing condition in the abs max section of the datasheet but for more detailed information, please reference this graph:

You can find this in the following app note: https://www.ti.com/lit/an/slvae30e/slvae30e.pdf

Please note that TPS4H160 is the 4 channel version of TPS2H160 so the same graph can be used.

Thanks,

Thanks, Shreyas.

Another question: Is it possible to operate the device between 40 Hz to 100 Hz?

Hi Archie,

It is possible to PWM the device between 40Hz and 100Hz. Please note that we state the maximum amount of inductive energy for a single pulse on the Abs max section of the datasheet.

Thanks,
