Pinout
The NCP1729SN35T1G is a voltage detector IC manufactured by ON Semiconductor. It is designed to monitor the supply voltage in microcontroller and microprocessor-based systems and generate a reset signal when the monitored voltage drops below a specified threshold.
This component typically comes in a SOT-23-5 package, which means it has 5 pins. The function of each pin generally includes:
1. VCC (Supply Voltage): Connects to the monitored voltage.
2. GND (Ground): Connects to the system ground.
3. MR (Manual Reset Input): Allows for manual reset triggering.
4. RESET (Reset Output): Outputs the reset signal when the monitored voltage is below the threshold.
5. NC (No Connect): Not connected internally.
These pins work together to ensure the system is properly reset during undervoltage conditions to prevent unreliable operation. The "35" in the part number typically indicates the specific voltage threshold level, which in this case is 3.5 volts. Always refer to the manufacturer's datasheet for precise pin configuration and operational details.
