resulting in a completely latchup-proof switch. In junction isolation (no trench used), the N and P wells of the PMOS and NMOS transistors form a diode which is reverse-Collins biased in normal ...

The SMIC18_PSW_02 is a 3.3V PMOS power switch connecting the main supply and the core area. This IP includes a 3.3V input and a 3.3V output with one enable control pin (3.3V signal, low enable). It ...

I'm trying to make a latch switch with a tactile button ... Also should I use NPN transistor with a voltage rating same as PMOS that I'm using? I'm not sure what parameters that I should look for NPN ...

The GSMC18_PSW_02 is a PMOS power switch between the main power supply and circuit cell. Its RON is 1ohm.

Has there be precedents of the Zener configuration? Also, if we are trying to switch Q_1 with a square wave of 20μs period, would the Zener solution work to the speed? Matt, I spoke to our ...
