Pinout
The MAX6447UK46L is a supervisory IC designed to monitor the power supply voltage in microprocessor-based systems. It is part of the MAX6447/MAX6448/MAX6449 family, providing voltage monitoring and reset functionality.
The MAX6447UK46L typically comes in a small package, such as a SOT-23, which is a 5-pin configuration. The key functions of the pins are as follows:
1. GND (Ground): This pin is connected to the ground of the system.
2. VCC (Supply Voltage): This pin connects to the monitored supply voltage.
3. RESET: This active-low output pin triggers a reset signal to the microprocessor when the monitored voltage falls below a specified threshold.
4. MR (Manual Reset Input): This pin allows manual triggering of the reset function.
5. RESET (Complementary Reset Output): This active-high output works in conjunction with the RESET pin to provide a complementary reset signal.
This IC ensures that the microprocessor is held in reset until the supply voltage is sufficient for reliable operation, thereby preventing incorrect operation during power-up, power-down, and brownout conditions.
