Pinout
The MAX6373KA+T is a voltage monitor IC from Maxim Integrated, designed for monitoring power supplies in various electronic applications. It typically comes in a SOT-23 package, which has 3 pins. Here are the pin functions:
1. GND (Pin 1): This is the ground pin and serves as the reference point for the IC.
2. RESET (Pin 2): This pin outputs the reset signal. It is an active-low output that goes low when the monitored voltage falls below the specified threshold, signaling a power fault condition.
3. VCC (Pin 3): This is the supply voltage pin. The voltage at this pin is monitored by the IC to determine if it is within the acceptable range.
The MAX6373 series provides a simple solution for power supply monitoring by generating a reset signal to ensure that microcontrollers and other digital components operate correctly during power-up, power-down, and brownout conditions.
