Advantages and Disadvantages

Advantages

• Precise voltage monitoring protects electronic circuits from overvoltage and undervoltage conditions.
• Adjustable threshold voltage allows customization for different applications.
• Low quiescent current minimizes power consumption.
• Manual reset input provides flexibility in controlling the reset function.

Disadvantages

• Limited operating temperature range (-40°C to +85°C).
• Output type is limited to active-low.

Working Principles

NCP380HSNAJAAT1G operates by continuously monitoring the voltage level at the TH pin. When the voltage falls below the set threshold, the RESET pin goes low, indicating a fault condition. The manual reset input (MR) allows for external control of the reset function. The reset timeout period can be adjusted to determine how long the reset output remains low after the voltage returns to normal.
