Pin 1: VDD (Supply Voltage)
Pin 2: GND (Ground)
Pin 3: MR (Manual Reset)
Pin 4: RESET (Reset Output)
Pin 5: VOUT (Voltage Detection Output)

Functional Features

1. Voltage Detection: The S-80944CNPF-G9ETFU can accurately detect the input voltage within the specified range.
2. Reset Function: It provides a reset output signal when the detected voltage falls below the threshold level.
3. Manual Reset: The manual reset pin allows for an external reset signal to override the internal detection.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• Low supply current consumption
• High accuracy in voltage detection
• Small package size for space-constrained applications
• RoHS compliant

Disadvantages

• Limited output current capacity (5mA maximum)

Working Principles

The S-80944CNPF-G9ETFU operates by continuously monitoring the input voltage. When the voltage falls below the preset threshold level, the reset output is activated. The manual reset pin can be used to force a reset regardless of the voltage level.

Detailed Application Field Plans

The S-80944CNPF-G9ETFU is widely used in various electronic devices that require voltage monitoring and reset functionality. Some common application fields include:

1. Microcontrollers: Ensuring proper system initialization and preventing data corruption during power fluctuations.
2. Battery-Powered Devices: Protecting the battery from over-discharge by triggering a reset when the voltage drops below a safe level.
3. Power Management Systems: Enabling efficient power management by monitoring supply voltages and initiating appropriate actions.

Detailed and Complete Alternative Models

1. S-80944CNPF-G9ETFG: Similar to S-80944CNPF-G9ETFU, but with an active-high reset output.
2. S-80944CNPF-G9ETTJ: Offers additional features such as adjustable detection voltage and hysteresis control.
3. S-80944CNPF-G9ETTW: Provides a push-pull reset output instead of an open-drain configuration.

These alternative models offer similar functionality with slight variations to cater to specific application requirements.
