Product Overview: Maxim Integrated MAX813LESA-T

The MAX813LESA-T is a high-performance microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a renowned leader in the development of innovative analog and mixed-signal products. This compact and efficient device is engineered to monitor power supplies in µP and digital systems, providing a significant enhancement to system reliability and robustness.

The MAX813LESA-T offers a combination of features that make it an ideal solution for a wide range of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring. Its primary function is to assert a reset signal whenever the VCC supply voltage falls below a preset threshold, ensuring the µP resets properly during power-up, power-down, and brown-out conditions.

Key Features:

• Precision Monitoring: The device includes a precision voltage monitor with a factory-set reset threshold voltage, ensuring accurate and reliable system operation.
• Manual Reset Capability: An additional manual reset input allows for a reset to be triggered with an external push-button or logic signal, providing enhanced control and flexibility.
• Low Power Consumption: With its low supply current draw, the MAX813LESA-T is an energy-efficient choice for battery-operated devices.
• Power-On Reset Delay: The integrated power-on reset delay timer gives the system processor sufficient time to stabilize before resuming operation, reducing the risk of system errors.
• Compact Package: Housed in an 8-pin SO package, the MAX813LESA-T saves valuable board space and is suitable for space-constrained applications.

The MAX813LESA-T also features an active-low reset output, which remains asserted for a minimum of 140ms after VCC has risen above the reset threshold. This ensures a proper reset signal duration for most µP and digital systems. The device operates over a wide temperature range, making it suitable for industrial and automotive environments where temperature extremes are common.

Overall, the Maxim Integrated MAX813LESA-T supervisory circuit is a reliable and essential component for maintaining system integrity and preventing data corruption due to unpredictable power supply conditions.
