Product Overview: MAX813LCSA-T by Maxim Integrated

The MAX813LCSA-T is a sophisticated microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal products. This device is engineered to improve the reliability of power-sensitive digital systems by providing essential functions such as power-on reset control, watchdog timer, and manual reset capability.

Key Features

• Power-On Reset: The MAX813LCSA-T generates a reset signal whenever the supply voltage falls below a preset threshold, ensuring that the µP starts in a known state. This feature is critical for preventing erroneous operation at power-up.
• Watchdog Timer: To prevent system hangs and malfunctions, the integrated watchdog timer monitors the system activity and generates a system reset if the µP fails to provide regular kicking signals within a specific time frame.
• Manual Reset Input: This feature allows for an external trigger to initiate a system reset, providing an additional layer of control for system maintenance or debugging purposes.
• Low Power Consumption: The MAX813LCSA-T is designed for low-power operation, making it an ideal choice for battery-operated and portable devices where power efficiency is paramount.
• Compact Package: Available in an 8-pin SOIC package, the device requires minimal board space and is suitable for high-density PCB designs.
