Pinout
The MAX809TTRG is a voltage monitoring IC from Maxim Integrated. It is part of the MAX809 series of microprocessor supervisory circuits. The device is typically housed in a 3-pin SOT-23 package.
Pin Count:
- The MAX809TTRG has 3 pins.
Function:
- Pin 1 (GND): Ground reference for the device.
- Pin 2 (RESET): This is an active-low reset output. When the monitored voltage drops below a specified threshold, the RESET pin is driven low. It remains low for a specified timeout period after the voltage rises above the threshold, thereby ensuring a stable startup.
- Pin 3 (VCC): Supply voltage input. The device monitors the voltage level on this pin.
The MAX809TTRG is used to monitor the supply voltage of microprocessor systems and to generate a reset signal to prevent erratic operation when the supply voltage falls outside acceptable levels.
