Package

The MAX825TEUK+T comes in a TDFN (Thin Dual Flat No-lead) package type. This compact, surface-mount package is designed for space-saving applications while providing efficient thermal performance.

Pinout

The MAX825TEUK+T is a voltage supervisor and reset generator from Maxim Integrated. It comes in a 5-pin SOT23 package.
### Pin Count and Functions:
1. Pin 1 (GND): Ground reference for the device.
2. Pin 2 (VOUT): Output voltage that goes low when the monitored voltage falls below the preset threshold.
3. Pin 3 (VCC): Supply voltage input, typically from 1.5V to 5.5V.
4. Pin 4 (RESET): Active-low reset output; goes low when the input voltage drops below the threshold and remains low for a defined delay after the voltage returns to normal.
5. Pin 5 (RESET): Same as pin 4; typically used for redundancy or alternative reset outputs.
The device ensures proper system operation by providing reset signals during power-up, power-down, and brownout conditions.
