The MAX6319MHUK46CY-T is an integrated circuit (IC) component manufactured by Maxim Integrated. It is a voltage monitor and reset circuit that provides power supervision, watchdog, and manual reset functionality for microprocessors, microcontrollers, and other digital devices. This IC is commonly used in various applications where reliable power supply monitoring is required to ensure proper system operation.
Key features of the MAX6319MHUK46CY-T include:
1. Voltage Monitoring: The MAX6319MHUK46CY-T monitors the supply voltage and provides a reset signal to the microprocessor or controller when the voltage drops below a predefined threshold. It ensures that the system does not operate outside the normal voltage range, preventing data corruption or erratic behavior.
2. Adjustable Reset Threshold: This IC allows the user to set the desired reset threshold voltage using external resistors. This flexibility enables customization based on specific system requirements.
3. Manual Reset Input: The MAX6319MHUK46CY-T features a manual reset input pin that allows an external push-button or switch to generate a reset signal when pressed. This feature ensures that the system can be reset manually in case of a software hang-up or other issues.
4. Watchdog Timer: This IC incorporates a watchdog timer that monitors the system's operation. If the system fails to toggle the watchdog input within a specified time period, the MAX6319MHUK46CY-T generates a reset signal, ensuring proper system recovery.
5. Debounced Manual Reset: To avoid false triggering, this IC provides a debounced manual reset input. It requires the manual reset switch to be stable for a certain duration before generating a reset signal.
6. Active-Low Reset Output: The reset output of the MAX6319MHUK46CY-T is active-low, meaning it becomes low when a reset condition is present. This signal can be directly connected to the reset pin of the microprocessor or controller.
7. Power-On Reset: Upon power-up, the MAX6319MHUK46CY-T ensures that the reset output stays low until the supply voltage reaches a stable operating level. This feature serves to avoid any inadvertent system startup during power-up transients.
8. Low Power Consumption: The MAX6319MHUK46CY-T is designed to consume minimal power, making it suitable for battery-powered applications. It also includes a power-saving feature where the supply current can be reduced when the device is inactive or in standby mode.
9. Wide Temperature Range: This IC is specified to operate over an extended temperature range, typically from -40
