MAX1232EPA Description

Short technical summary and product information.

The MAX1232EPA from Analog Devices is a microprocessor (μP) supervisory circuit that provides essential μP housekeeping and power-supply supervision functions. It consumes significantly less power than older designs like the DS1232, making it ideal for modern systems.

 

Key features include a precision voltage monitor with adjustable thresholds, a reset pulse of at least 250ms duration on power-up, power-down, and brownout conditions. It also includes a debounced manual reset input for external override and a digitally programmable watchdog timer with selectable timeout settings of 150ms, 600ms, or 1.2s. This device requires no external components for operation.

 

The MAX1232EPA is available in an 8-pin PDIP package, suitable for through-hole mounting. It operates across a temperature range of -40°C to 85°C (TA), ensuring reliability in various environmental conditions. Applications include computers, controllers, intelligent instruments, and critical μP power monitoring.

 

This supervisory circuit monitors a single voltage and provides active high/active low reset outputs. The output type is open drain or open collector. The device is designed for robust system performance in demanding applications.
