8.3.2 Adjustable Pulse Duration

The CT pin enables the ability to set a user-defined time delay in order to ensure that the fault condition is recognized. The external capacitor charges based on an internal current source until the voltage at the CT pin exceeds that of the internal reference voltage.

The time delay is determined by the value of the external capacitor CT : td ≈ 2.6 × 104 × CT , where CT is in farads (F) and td is in seconds (s).

The current source to charge the timing capacitor varies ±15%. Reference Voltage 2 is approximately 1.8 V and varies approximately ±5%. Once the timing capacitor charges, it discharges to about 0.6 V, not completely to 0 V.
