00:00How To Achieve Zero Power Consumption

00:02Voltage Detection Optimization Solution

00:05Welcome to YB's Science Corner

00:07When the GPIO voltage is low or the battery voltage is high

00:12We need a stronger and more flexible solution 3

00:15Option 3 Fully Controlled PMOS Switch

00:19If the minimum value of VGs required by the MOS transistor cannot be met

00:24Switch to PMOS and add more components

00:30Taking a 12V battery as an example

00:33VG's technology is minus 12V at the moment of conduction

00:37According to the O3401 a datasheet right at the tipping point

00:42To solve this problem

00:44We can divide the voltage by connecting a resistor R4 in series with R3 at the gate

00:49Make sure that the absolute value of VGs is always within safe limits

00:54Option 4 Summary and Comparison

01:00Let's wrap it up quickly

01:02From Plan 1 to Plan 3 we add a small number of components

01:06Successfully using flexibility and cost

01:09In exchange for zero shutdown power consumption and higher reliability

01:13That wraps up this episode's video content
