The ADM1232 is a superior, pin-compatible upgrade for the MAX1232 and the DS1232LP and DS1232. It is a microprocessor monitoring circuit that can monitor the microprocessor supply voltage, whether the microprocessor has locked-up, and an external interrupt. It features adjustable precision voltage monitor, adjustable STROBE monitor, low power consumption, and is suitable for various applications including microprocessor systems, portable equipment, computers, controllers, intelligent instruments, and automotive systems.
The ADM1232 is a microprocessor monitoring circuit designed to monitor supply voltage, detect microprocessor lock-ups, and handle external interrupts. It serves as a superior, pin-compatible upgrade for the MAX1232 and Dallas DS1232LP/DS1232 devices. The circuit is available in four different packages: 8-lead microSOIC, 8-lead PDIP, 16-lead wide SOIC, and 8-lead narrow SOIC.
