MAX1232EPA

Supervisors Overview

The MAX1232EPA is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features two fixed threshold voltages at 4.37 V and 4.62 V. The device provides an open-drain or open-collector output with selectable active-high or active-low reset polarity. It includes a minimum reset timeout of 250 ms and supports manual reset functionality. The component is housed in an 8-DIP package with a pin pitch of 0.300 inches (7.62 mm) and is designed for through-hole mounting. It functions as a simple reset/power-on-reset supervisor.
