The ADM1232ARWZ is a supervisory circuit manufactured by Analog Devices. It typically comes in an 8-pin SOIC package. The main function of the ADM1232ARWZ is to monitor power supply levels and provide a reset signal to ensure proper microprocessor operation.
Key functions and pin descriptions include:
1. RESET (Pin 1): An active-low reset output that asserts when the monitored supply voltage dips below a preset threshold or when the watchdog timer is not serviced.
2. RESET (Pin 2): An active-high reset output that functions similarly to the RESET pin but with opposite polarity.
3. TOL (Pin 3): Tolerance pin that selects the threshold voltage for the reset circuitry.
4. GND (Pin 4): Ground reference for the device.
5. WDI (Pin 5): Watchdog input, which should be toggled periodically to prevent the RESET signal from being asserted due to a timeout condition.
6. VCC (Pin 6): Power supply input.
7. TD (Pin 7): Time delay input that sets the reset timeout period.
8. PBRST (Pin 8): Push-button reset input that allows an external switch to trigger a manual reset.
This arrangement ensures reliable operation by preventing system lock-up during power anomalies.
