ZT Trigger Mask Function

When switching is set ON/OFF, the superposition of noise may occur at the ZT pin. During this time, the detection

function is turned OFF for the duration of tZTMASK (Typ = 0.60 µs) to prevent the ZT pin part from false detection.

Figure 12. ZT Trigger Mask Function Timing Chart

A: DC/DC OFF → ON

B: DC/DC ON → OFF

C: Because noise occurs at the ZT pin, the ZT pin protection function is not operated for tZTMASK (Typ = 0.60 µs).

D: Same as A.

E: Same as B

F: Same as C

G: Same as A
