ADM1232A is a microprocessor monitoring circuit that can be used in microprocessor systems, portable equipment, computers, controllers, intelligent instruments, and automotive systems. It features low power consumption, adjustable precision voltage monitoring, and STROBE monitoring.
The ADM1232A is a superior upgrade for the MAX1232 and Dallas DS1232, designed as a low-power microprocessor monitoring circuit. It monitors microprocessor supply voltage, detects if the processor has locked up, and can monitor an external interrupt via a strobe input.
| Strobe Pulsewidth Detection | 20 ns |
|---|---|
| Operating Temperature Range | -40 to +85 °C |
| Reset Output Delay (VCC Falling) | 250 ms |
Connecting TOLERANCE to ground selects a -5% tolerance (reset below 4.75 V), while connecting it to VCC selects a -10% tolerance (reset below 4.5 V).
The internal debounce circuit guarantees a reset assertion if PB RESET is held low for more than 20 ms.
