The MAX809REUR+T is an IC (integrated circuit) component manufactured by Maxim Integrated. It is a microprocessor supervisory circuit designed to monitor the power supply voltage and reset the microcontroller unit (MCU) in case of voltage fluctuations or power supply failures.
This IC is widely used in embedded systems, battery-powered devices, and other applications where an accurate reset signal is required. It offers a range of key features that make it a popular choice among engineers and developers.
One of the notable features of the MAX809REUR+T is its low-power consumption. It operates with a supply voltage ranging from 1.1 volts to 5.5 volts, making it suitable for various low-power applications. The quiescent current is very low, typically measuring around 2.5 microamperes, which helps in minimizing power consumption and maximizing battery life.
Another significant feature offered by this IC is its precision voltage monitor. It has a built-in voltage reference and a comparator that continuously monitors the input power supply voltage. The user can set the desired voltage threshold by choosing external resistors. Once the input voltage falls below this threshold, the MAX809REUR+T generates a reset signal to restart the MCU, ensuring proper system operation.
Furthermore, the MAX809REUR+T incorporates a manual reset input pin. This pin allows the user to force a system reset by activating it externally
