Operation

STM1068

8/22

2

Operation

between PKX and POX is either enabled or disabled (see Table 2, Table 3 , and Figure 11

for more details).

2.1

Output, OUT

If the enable input is in a logic high state and inhibit input is in a logic low state, the output

output is connected to ground GND. The output is current limited (see Table 6).

2.2

Enable input, EN

the PKX and the device enters a standby mode with very low current consumption (see

Table 6).

2.3

Inhibit input, INH

follow the PKX.

2.4

Pass gate, PKX and POX

Pass gate between PKX and POX is disabled only if enable input is in logic high, inhibit input

is in logic low and the supply voltage is below the voltage threshold.
