TPS3851-Q1: How much is the Maximum VOL at VDD=3.3V?

Part Number: TPS3851-Q1

Hi team,

I would like to know the maximum VOL of TPS3851G33EQDRBRQ1 at VDD=3.3V.

VOL maximum is specified at VDD=5.0V and Ireset=3mA and is 0.4V.

Since the VIL max of the target IC's reset pin is 0.35V, I would like to know if this is feasible to control using this device at VDD=3.3V.

It is nice if you can share VDD=3.3V version of Figure13 and Figure14 in the datasheet.

regards,

    Hi 

    VOL depends on the RESET current and the VDD (overdrive) voltage. There is plot for worst case VOL vs IRESET at  VDD = 1.6V . VDD = 3.3 Volt will perform better than that. 

    By looking at figure 12 in datasheet, you can conclude that VOL will be less than 0.35 for IRESET<2mA for VDD = 3.3V
