Detecting a drop in power supply voltage! Introducing a design example of a power supply voltage detection circuit.
We would like to introduce a design case of Frontier Technology: "Power Supply Voltage Detection Circuit." This circuit detects a drop in power supply voltage and outputs the detection result when the power supply voltage falls below a set comparison voltage. It is suitable for applications such as mobile devices that require battery operation and has a track record of being implemented in low-power microcontrollers. 【Layout Design Points】 - Arrange and route the differential pair of the comparator considering the direction of current and surrounding patterns. - Place dummy resistors around the voltage divider resistors as a measure to prevent resistance value errors due to etching, ensuring the stabilization of the resistance value of one unit. *For more details, please refer to the PDF document or feel free to contact us.
