Pinout

The MAX803LEXR is a microprocessor supervisory circuit designed to monitor power supply levels in microcontroller or microprocessor systems. It typically comes in a SOT-23 package, which has 3 pins.
The pin functions are as follows:
1. GND (Pin 1): Ground reference for the device.
2. RESET (Pin 2): Active-low reset output. This pin goes low when the monitored supply voltage drops below the reset threshold, and remains low for a specified reset timeout period after the supply voltage exceeds the threshold again.
3. VCC (Pin 3): Supply voltage input. This pin is connected to the power supply being monitored.
The MAX803LEXR is often used to ensure that the system is reset in a controlled manner when power supply fluctuations occur, protecting against undefined states during power-up, power-down, and brownout conditions.
