TPS775xx RESET Timing Diagram
(1) V
res
is the minimum input voltage for a valid RESET. The symbol V
res
is not currently listed within EIA or JEDEC
standards for semiconductor symbology.
(2) V
IT
: Trip voltage is typically 5% lower than the output voltage (95% V
OUT
). V
IT –
to V
IT+
is the hysteresis voltage.
