Pinout
The MAX809MTRG is a microprocessor supervisory circuit manufactured by Maxim Integrated. It is available in a SOT-23 package with a 3-pin configuration. The primary function of the MAX809MTRG is to monitor the supply voltage of microprocessor systems and provide a reset signal to ensure proper operation during power-up, power-down, and brownout conditions.
The 3 pins are typically configured as follows:
1. Pin 1 (GND): Ground pin.
2. Pin 2 (RESET): Active-low reset output. This pin is asserted (pulled low) whenever the monitored voltage drops below a specified threshold, resetting the connected microprocessor.
3. Pin 3 (VCC): Supply voltage input that monitors the system’s voltage level.
The MAX809MTRG is designed to increase system reliability by preventing undefined operation when the power supply is insufficient or unstable. It operates with low supply current and is suitable for portable and battery-powered devices.
