Pinout
The MAX706MJA is a microprocessor supervisory circuit that comes in a 8-pin dual in-line package (DIP). Its primary functions include monitoring supply voltage and providing a reset signal when the power supply is below a specified threshold.
Pin configuration is as follows:
1. VCC: Supply voltage input.
2. GND: Ground connection.
3. RESET: Active-low reset output.
4. RESET/SHDN: Reset output and shutdown control.
5. VTH: Voltage threshold select input (for setting reset threshold).
6. VREF: Reference voltage output.
7. NC: No connection (not internally connected).
8. VCC (again): Another supply voltage input.
The MAX706MJA ensures proper operation of microcontrollers by holding the RESET line low during power-up and providing a reset signal when the supply voltage falls below the preset threshold.
