MAX809LTRG

The MAX809LTRG is a microprocessor supervisory circuit designed to monitor the supply voltage in digital systems and generate a reset signal to ensure proper operation. It is commonly used in applications to prevent microcontrollers and other digital circuits from operating under insufficient power conditions, which can lead to undefined behavior.
This device features a precision voltage reference and comparator circuit that monitors the power supply voltage. If the voltage drops below a predefined threshold, the MAX809LTRG asserts a reset signal. The reset remains active until the voltage returns to an acceptable level and stabilizes, ensuring the system restarts correctly.
Key features include low supply current, ensuring minimal power consumption, and a variety of voltage threshold options to suit different applications. It is available in compact, surface-mount packages, making it suitable for space-constrained designs.
The MAX809LTRG is widely used in battery-powered devices, embedded systems, and any application requiring reliable power supervision to protect against data corruption or system malfunction due to power issues.

The MAX809LTRG is a microprocessor supervisory circuit designed to monitor power supplies in digital systems. It typically comes in a SOT-23 package and features a 3-pin configuration. The pin count and functions are as follows:
1. Pin 1 (GND): Ground pin, which is connected to the system ground.
2. Pin 2 (RESET): This is the active-low reset output pin. When the monitored voltage drops below the specified threshold, this pin goes low, initiating a reset process to the microprocessor.
3. Pin 3 (VCC): Supply voltage pin. This is connected to the voltage that the device is monitoring.
The MAX809 supervises the power supply voltage level and provides a reset output to ensure the microprocessor operates correctly and safely during power-up, power-down, and brownout conditions.
