The MAX793TESE from Maxim Integrated is a high-performance, low-power microprocessor (µP) supervisory circuit designed 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 with 5V-powered circuits.

This device significantly improves system reliability and accuracy compared to separate ICs or discrete components. The MAX793TESE offers several key features that make it a robust solution for complex electronic systems. It includes a precision voltage monitor with a 4.65V threshold, a 200ms (min) power-on reset delay, which ensures a proper system reset, and a manual reset capability.

The voltage monitor watches the power supply voltage of a microprocessor (µP), and it asserts a reset if the supply voltage drops below a preset threshold. The reset output remains asserted for the duration of the reset timeout period after the supply voltage rises above the reset threshold. This ensures that the µP and other system components are held in the reset state until conditions are stable for correct operation.

The MAX793TESE comes in a 16-pin narrow SO package, making it suitable for space-constrained applications. Its temperature range of -40°C to +85°C allows for operation in diverse environmental conditions, suitable for many industrial applications.

Key features of the MAX793TESE include:

• Precision Monitoring of +5V Power-Supply Voltages
• Fully Specified Over Temperature
• 200ms (min) Power-On Reset Pulse Width
• Manual Reset Input
• Debounced TTL/CMOS-Compatible Manual Reset Input
• 16-Pin Narrow SO Package

Overall, the Maxim Integrated MAX793TESE is an ideal solution for system designers looking to enhance the reliability and performance of their power monitoring systems. Its combination of features and compact form factor makes it a valuable addition to a wide range of electronic products.
