The S-80942ALMP-DA6-T2 is a voltage detector manufactured by SII Semiconductor Corporation. It is designed to monitor voltage levels in electronic circuits and provide a reset signal when the voltage falls below a specified threshold. This ensures that the system starts up or operates correctly, preventing data corruption or malfunction.

Applications

• Microcontroller reset circuits
• CPU reset circuits
• Power supply monitoring
• Battery-powered devices
• Industrial control systems

Features

• Detection voltage: 4.2V (This is implied from the part number, common voltage detection range for these series)
• High-accuracy detection voltage
• Low current consumption
• Small package size (likely SOT-23 or similar)
• Built-in hysteresis
• Open drain output

Benefits

• Prevents system malfunction due to low voltage
• Ensures reliable system startup
• Extends battery life in portable devices due to low current consumption
• Reduces board space requirements due to small package size
• Provides a clean and reliable reset signal to the microcontroller or CPU

Additional Details

The S-80942ALMP-DA6-T2 features a built-in hysteresis, which prevents the output signal from oscillating when the input voltage is near the threshold. The open drain output allows the device to be easily interfaced with a variety of microcontrollers and other digital circuits. This voltage detector is ideal for use in a wide range of applications where reliable voltage monitoring is required.

The device's low current consumption makes it suitable for battery-powered applications where minimizing power usage is critical. The high-accuracy detection voltage ensures that the reset signal is generated precisely when needed, preventing false resets or delayed resets. The small package size allows for easy integration into compact electronic designs.
