The MAX1232ESA is a microprocessor supervisory circuit designed to enhance system reliability by monitoring power supply and software execution. It offers a precision voltage monitor with adjustable thresholds and provides a debounced manual reset input. This device consumes significantly less power than older models like the DS1232.
Key electrical specifications include a nominal supply voltage of 5V, with selectable 5% or 10% supply tolerances. The reset pulse width is a minimum of 250ms, ensuring stable system resets during 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 requires no external components, simplifying circuit design. It is available in an 8-pin SOIC package, suitable for surface mounting. The operating temperature range is from -40°C to +85°C, making it suitable for a variety of applications including computers, controllers, and intelligent instruments where critical μP power monitoring is required.
The supply voltage is 5V nominal.
The package is 8-SOIC.
The operating temperature range is -40°C to 85°C.
The adjustable watchdog timer can be set to 150ms, 600ms, or 1.2s.
The reset pulse width is 250ms minimum.
The voltage thresholds are 4.37V and 4.62V.
The reset can be active high or active low.
