The MAX1232ESA is a microprocessor supervisory circuit from Analog Devices, offering enhanced reliability for μP systems. It monitors power supply, software execution, and provides a debounced manual reset input. This device consumes significantly less power than the DS1232 and requires no external components.
Key electrical specifications include adjustable voltage thresholds of +4.5V or +4.75V, with selectable 5% or 10% supply tolerances. The reset pulse duration is a minimum of 250ms, ensuring proper system reset on power-up, power-down, and brownout conditions. A digitally programmable watchdog timer can be set for timeout periods of 150ms, 600ms, or 1.2s to monitor software execution.
This supervisor IC is available in an 8-pin SOIC package, suitable for surface mounting. It operates within a temperature range of -40°C to +85°C (TA). The MAX1232ESA is designed for applications such as computers, controllers, intelligent instruments, and critical μP power monitoring.
Its output is open drain or open collector, with reset active high or active low. The device monitors a single voltage channel. The MAX1232ESA serves as a plug-in upgrade for the Dallas DS1232, providing a more power-efficient solution.
