TPS2552: Hysterisis of Enable Pin

Intellectual 630 points
Part Number: TPS2552

Hello, 

From the datasheet, I understand that to guarantee TPS2552 in ON condition, the enable pin voltage should be less than 0.66V & to guarantee TPS2552 in OFF condition, the enable pin voltage should be greater than 1.1V. Please can you share the Hysteresis associated with these 2 Thresholds of Enable Pin.

    Hi Poster,

    For TPS2552, logic low turns on power switch. From the test validation results, under VIN=6.5V temperature=25, the mean EN voltage at rising edge is 0.79V and the mean EN voltage at falling edge is 0.74V. The difference from these two values is 50mV.
