There are generally six power modes in an MCU: Run: In full run mode, an MCU consumes full current. This mode is best suited for applications where power efficiency is not essential. Doze: As we know, power increases proportionally to the frequency. Therefore, we can conclude that higher clock speeds tend to higher power consumption.…

Selecting components is one of the most essential and critical processes when designing any electronic system. Poor component selection can lead to many problems within the design, PCB layout, power budget, etc. In this article, we will discuss how to select a component for a low-power-optimized design. Resistor The power dissipated by a resistor is…

A battery-management system (BMS) is an electronic system or circuit that monitors the charging, discharging, temperature, and other factors influencing the state of a battery or battery pack. It’s used to monitor and maintain the health and capacity of a battery. Today’s BMS devices are advanced and will often provide pop-up notifications as you’ve likely…

EMC testing is essential to get a certification of Electromagnetic Emission and Immunity test before launching the product in the market. However, actual EMC tests are pretty expensive. Before going for the actual EMC test, the product should test in EMC pre-compliance test Lab. Pre-compliance testing will mimic all tests performed at EMI/EMC test labs…

In the previous article, we learned about EMI/EMC pre-compliance test. EMS/EMC pre-compliance immunity test is required before the compliance test. EMS/EMC pre-compliance immunity test will give the confidence to pass the compliance test. The pre-compliance immunity test simulates all the tests done at the compliance test lab, but it is unnecessary to apply all the…
