MAX1232CPA Description

Short technical summary and product information.

The MAX1232CPA is a microprocessor supervisory circuit designed by Analog Devices, Inc. This component offers essential μP housekeeping and power-supply supervision functions, consuming significantly less power than comparable devices like the DS1232. It enhances system reliability by monitoring the power supply and software execution, and includes a debounced manual reset input.

 

Key electrical specifications include a precision voltage monitor with adjustable thresholds of +4.5V or +4.75V, and a reset pulse width of 250ms minimum. It features a digitally programmable watchdog timer with timeout settings of 150ms, 600ms, or 1.2s. The device operates within a temperature range of 0°C to 70°C (TA).

 

Packaged in an 8-pin PDIP with through-hole mounting, the MAX1232CPA requires no external components. Its output is open drain or open collector, with reset active high or active low. This supervisor IC is suitable for applications in computers, controllers, intelligent instruments, and critical μP power monitoring.

 

The MAX1232CPA is a plug-in upgrade for the Dallas DS1232, offering improved power efficiency and advanced features for robust system design.
