The MAX803LEXR+T is a microprocessor supervisory circuit designed to monitor the power supply in microprocessor systems. It typically comes in a 3-pin SOT-23 package. The primary function of this device is to provide a reset signal whenever the power supply voltage levels fall below a specific threshold, ensuring the microprocessor is safely reset and preventing incorrect operation during power-up, power-down, or brownout conditions.
The 3 pins have the following functions:
1. Pin 1 (GND): Ground reference for the device.
2. Pin 2 (VCC): Input supply voltage monitored by the device. It is the main power supply pin.
3. Pin 3 (RESET): Active-low reset output. It remains low when VCC is below the reset threshold, ensuring the microprocessor stays in reset until the supply voltage is stable.
This supervisory circuit is part of the MAX803 series, which features different reset threshold voltages to cater to varying system requirements.
