Microprocessor Supervisory Circuit

The ADM1232A is pin-compatible to the MAX1232, DS1232LP, and DS1232. The ADM1232A can detect strobe pulse widths as narrow as 20 ns, making it compatible with high speed microprocessors. The Analog Devices, Inc., ADM1232A is a microprocessor monitoring circuit that monitors micro-processor supply voltage. It can also detect if a microprocessor has locked up or an external interrupt has been issued. The ADM1232A is available in an 8-lead narrow body SOIC and is specified over the −40°C to +85°C temperature range.
