Latching Power Circuit in Kicad
Will a 10K pulldown resistor at the trigger improve the performance?
I ran a simulation Multisim Power Saving Latching Circuit which confirms the advantages.
The voltage at the base will be drained with the pulldown from 25% of VCC to <1mV.
The power consumption lowers from 4 µA to 0,04 µA.
According to the schematic a 220 ohm resistor (and a diode) is connected to the MCU pin.
The expected power consumption will be approx. 10mA (3,3V - 0,7 VF) / 220 Ohm.
For the MOSFET to function a voltage of 20mV at the gate is more than sufficient.
I ran a simulation Multisim Power Saving Latching Circuit.
If R6 is 2,2K Ohm the power is 1mA and the MOSFET gate is still < 20mV.
If R6 is 22K Ohm the power is 0,1mA and the MOSFET gate is still 23mV.
If R6 is >100K Ohm in combination of R8 the remaining amperes becomes too little.
So it is an easy gain to lower the power consumption and safeguard the pin current by raising it to 2,2K Ohm.
