Disadvantages

• Limited threshold voltage options may not suit all applications
• Manual reset input requires external control signal

Working Principles

The MAX8213BMJE operates by continuously monitoring the supply voltage. When the voltage drops below the selected threshold, the reset output is asserted, indicating a power failure or low voltage condition. The reset signal remains active until the voltage rises above the threshold or a manual reset signal is applied to the MR pin. The reset timeout period can be adjusted using an external capacitor connected to the CT pin.
