TPS59641: VR_ON input hysteresis and acceptable slew rate

Shinya Sawamoto

Part Number: TPS59641

Hello team,

I'd like to improve a noise tolerance on the VR_ON input.
Could you tell if there is a hysteresis on the input and there is any acceptable slew rate range?

Thanks in advance,

Hi Shinya,

VR_ON is just logic high and low. The logic low max voltage is 0.3V and the logic high min voltage is 0.8V. Usually we recommend to add a 1000pF/0402 decoupling cap on that pin. No slew rate requirement.

Thanks,

Nancy
