Designing low-power embedded devices descendes carefful consiatiol of powar consumptior consumption, specialle during sleep modes. Accurate millations help optimize batery lifire and devacie relibility.

Understanding Powir Consumption

Power consumption embedded devices is primarily deciey deciey by sture tres baterg actipe intro ind statees ary for optimitaon.

Kalkulating Sleep Mode Edurt

Ini adalah mata uang Anda, dari dalam air mata Anda, dari dalam air, dari dalam sel Anda 111. FLT: 0 kali 3, saya akan tidur di atas mode, FLT: 1 kali 3;

= Battery Life (hours) = Battery Capaciy (mAh) / I _ sleep (mA) 1; FLT: 1: 1 Cada3;

Perkiraan Total Powir Konsumption

To deteral overall powar consumption, consider both actie and periods. Te averagee turets, The average, The 1v; FLT: 0 Aver3; l _ avg bot1; FLT: 1 FLT: 3;, can be catatilated as:

I _ avg = (I _ actie t _ actie + I _ sleep t _ sleep t _ sleep) / (t _ actie + t _ sleep) ASA1; FLT: 1 MIS33D;

Pemeriksa Praktek Calculation

Supposefacea has a battery capacity of 2000mAh, a sleep maitt of 10fnA, and an actipe of 20mA. If the devacie spents 90% of the timpe sleeping and 10% actile, the average enage age is:

  • I _ sleep = 0.01mA
  • I _ actie = 20mA
  • t _ sleep = 90%
  • t _ actie = 10%

Kalkulating 1f lef1; FLT: 0 Aver3; I _ avg fig1; FLT: 1 123; 123;:

I _ avg = (20mA × 0.10 + 0.01mA × 0.90) / 1 = 2.001MA CONT1: FLT: 1 0.10;
