The MAX809STRG is a microprocessor reset circuit designed to monitor the supply voltage in digital systems and provide a reset signal to the processor during power-up, power-down, and brownout conditions. It typically comes in a small SOT-23 package.
Pin Count and Functions:
1. 3 Pins:
- Pin 1 (GND): Ground pin connects to the system ground.
- Pin 2 (RESET or RESET): Depending on the variant, this pin provides an active-low (RESET) or active-high (RESET) reset signal to the microprocessor.
- Pin 3 (VCC): Power supply pin connected to the monitored voltage.
The MAX809 monitors the VCC pin and asserts the RESET signal if the supply voltage drops below a predetermined threshold. Once VCC rises above the threshold, the reset signal is held active for a specified time delay, ensuring the microprocessor resets reliably.
