Hi,
If sense voltage reaches VITP before CT voltage hits VCT as following picture, How does CT pins and /RESET pins works?

Kuramochi-san,
The CT capacitor is charged by an internal current source as set by the user.This capacitor starts charging as soon as the RESET conditions are cleared. When the voltage on this capacitor reaches 1.22V, RESET is deasserted. If the device hits VITP before VCT is reached, the glitch immunity of the device should catch this condition, please see below:
