Kikusui TOS8030 - Example: Use of Signals

44 Status Signal Output TOS8030
7.2.2 Example: Use of Signals
■ Driving a DC buzzer using a FAIL signal
Fig. 7-2 Example: Use of FAIL Signal
■ Driving a lamp using an H.V ON signal
Fig. 7-3 Example: Use of an H.V ON Signal
■ Obtaining an L-level digital signal at signal output
Fig. 7-4 Conversion into a Logical Signal
In Fig. 7-4, “L”-level output is obtained at point “a” at signal output. However,
because a signal at point “a” contains contact chatter, measures for preventing con-
tact chatter are required, which measures are compatible with the subsequent circuit
to be connected. Moreover, the minimum applicable load for the contact is 5 V,
10 mA or greater. Thus, set V
+
and R values so that a load has this rating or above.
Other cases may require additional measures against noise.
