Functional Features

Voltage Detection

The S-80839CNPF-B8YTFU is designed to accurately detect the voltage level applied to its input pin. It compares the input voltage with a preset threshold and generates a reset signal when the voltage falls below the specified threshold.

Reset Output

When the voltage drops below the threshold, the RESET pin goes low, indicating a reset condition. This signal can be used to trigger various actions, such as restarting a microcontroller or resetting other circuitry.

Manual Reset (MR) Input

The MR pin allows for manual reset functionality. When this pin is pulled low, it forces the RESET pin to go low, regardless of the voltage level at the input pin. This feature provides flexibility in controlling the reset operation.

Advantages and Disadvantages

Advantages

• Wide voltage detection range enables compatibility with various electronic devices.
• Low supply current minimizes power consumption.
• High accuracy ensures reliable voltage detection.
• Small package size facilitates integration into space-constrained designs.
• RoHS compliance promotes environmental friendliness.

Disadvantages

• Limited number of available reset threshold voltage options.
• Lack of built-in hysteresis may lead to potential oscillations near the threshold voltage.

Working Principles

The S-80839CNPF-B8YTFU operates based on a voltage comparator circuit. It compares the input voltage with a reference voltage derived from an internal voltage divider network. When the input voltage falls below the preset threshold, the comparator triggers the reset output, indicating a low voltage condition.

Detailed Application Field Plans

The S-80839CNPF-B8YTFU finds applications in various electronic devices that require voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers: Ensuring proper operation by resetting the microcontroller when the supply voltage drops below a certain level.
2. Battery-powered devices: Protecting the battery from over-discharge by triggering a shutdown or warning when the voltage reaches a critical level.
3. Power management systems: Monitoring power supply voltages to detect faults or abnormal conditions and initiate appropriate actions.
