Functional Features

Voltage Detection

S-80939CLMC-G69T2U is designed to accurately detect voltage levels within the specified range. It monitors the voltage applied to the SENSE pin and compares it with the preset threshold voltage. When the voltage drops below the threshold, the RESET pin becomes active low, indicating a reset condition.

Reset Output

The RESET pin provides an active low signal when the voltage falls below the preset threshold. This signal can be used to trigger a reset operation in the connected electronic device.

Delay Circuit

The product incorporates a built-in delay circuit of approximately 200ms. This delay ensures stability during power-on and prevents false resets caused by momentary voltage fluctuations.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• High accuracy ensures reliable voltage monitoring.
• Low quiescent current minimizes power consumption.
• Compact package size enables integration into space-constrained designs.
• Built-in delay circuit enhances stability during power-on.

Disadvantages

• Limited number of available threshold voltage options.
• Active low reset output may not be compatible with all systems.

Working Principles

S-80939CLMC-G69T2U operates based on a voltage divider network connected to the SENSE pin. The voltage at this pin is compared with the preset threshold voltage using an internal comparator. When the voltage drops below the threshold, the comparator triggers the reset circuit, activating the RESET pin.
