Package

The NCT3933U is typically packaged in a 5-pin SOT-23 package.

Pinout

The NCT3933U is a voltage supervisor IC featuring a total of 5 pins. Its primary functions include monitoring supply voltage to ensure it stays within specified limits and providing reset signals to microcontrollers or other digital circuits when voltage drops below a predetermined threshold. The pin configuration is typically as follows:
1. VDD: Supply voltage input.
2. GND: Ground.
3. RESET: Active-low reset output, which goes low when the monitored voltage is below the threshold.
4. TEST: Used for internal testing purposes, often connected to GND in standard applications.
5. VTH: Voltage threshold setting, defining the voltage level at which the reset output is activated.
This IC is commonly used in power management applications to ensure reliable operation of digital systems.
