Maxim Integrated MAX791ESE-T Voltage Monitor

The MAX791ESE-T is a sophisticated, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in a variety of electronic applications.

This voltage monitor is particularly adept at protecting systems against low voltage, which can cause erratic operation. The MAX791ESE-T ensures that the µP boots up in a known state with its reset output feature. The reset output remains asserted for a minimum of 200ms after VCC has risen above the reset threshold level, ensuring a proper system reset. This function is crucial for systems that require a stable and reliable startup sequence.

The device comes in a narrow 16-pin SO package, designated by the "-T" suffix in its name, which implies tape and reel packaging suitable for automated assembly processes. Its small footprint makes it an excellent choice for space-constrained applications.

Key features of the MAX791ESE-T include:

• Precision monitoring of +5V, +3.3V, and adjustable voltage supplies.
• 200ms minimum power-on reset pulse width which guarantees a full system reset.
• Manual reset input, allowing for a system reset to be triggered as needed.
• Low supply current of 17µA, which is ideal for power-sensitive applications.
• Active-low and active-high reset outputs, providing flexibility in interfacing with different logic levels.
• Thermal shutdown protection, which safeguards the device and the system from excessive temperature.

With its robust feature set, the MAX791ESE-T is an essential component for ensuring the reliable operation of microprocessor-based systems, including computers, controllers, and intelligent instruments. Its ability to monitor multiple supply voltages simultaneously makes it a versatile solution for a wide array of applications where precise voltage supervision is critical.

Whether you are designing a new system or looking to enhance the reliability of an existing one, the MAX791ESE-T from Maxim Integrated provides the protection your system needs against the unpredictable nature of power supplies.
