This article discusses the application field and working principle of MAX800MEUE+, a member of the PMIC – Supervisors family.

The MAX800MEUE+ is an ultra-low-power voltage supervisor with specific applications in multiple markets, including automotive, consumer electronics, medical, and industrial. It features adjustable supply voltage monitors (SVMs) that allow for easy configuration of the thresholds for an undervoltage monitoring solution. This application versatility makes MAX800MEUE+ suitable for devices with dual supply voltages, as the SVM can be used to detect undervoltage conditions in multiple power distribution platforms.

The MAX800MEUE+ is equipped with 2 x SVM thresholds, one with a full-scale range of up to 5.5V and the other with a range of 6V. It also provides an adjustable reset delay time, which enables accurate measures in power-hungry applications. The robust design ensures the SVM is shock and vibration-resistant, and its advanced power switch keeps power consumption at a minimum. The supervisor also has an integrated brownout detector, which prevents battery drainage and improves overall system reliability.

To understand the working principle of the MAX800MEUE+ supervisor, we first must understand that a supervisor is a monitoring device that reacts to signals outside the normal range of a system, such as an undervoltage or overvoltage condition. The SVM in the MAX800MEUE+ acts as a “watchdog” for the voltage supply and triggers the device’s reset function when it detects conditions outside the specified voltage parameters. The adjustable delay time allows for higher accuracy when detecting the undervoltage conditions, allowing for the supervisor to accurately detect a low voltage state. Additionally, the integrated brownout detector functions by monitoring and detecting when the voltage supply is decreasing and thereby preventing a sudden unexpected power down of the system.

The MAX800MEUE+ has a wide range of applications, including automotive – durability testing, consumer electronics – system reset, medical – patient monitoring and industrial motor control. It can also be used to ensure reliable and safe monitoring of automotive and industrial systems, such as measuring the condition of a battery pack in an electric vehicle and monitoring the power levels of a motor during operation. Since it is a voltage supervisor, the MAX800MEUE+ is also used to detect overvoltage conditions and limit the amount of power entering the system.

Thanks to its efficient design, the MAX800MEUE+ can be used in many applications and markets. The adjustable SVM thresholds and brownout detector allow for very precise monitoring, maximizing system reliability and system uptime. Because of its low-power consumption and robust design, the MAX800MEUE+ is a top choice for monitoring a range of applications.
