DS1232LPSN+T&R

Supervisors Overview

The DS1232LPSN+T&R is a low-power MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.3 V to 5.5 V, with a maximum limit of 5.5 V and a typical overvoltage threshold of 4.74 V. The device features a single monitored input and provides active high, active low, and open drain outputs. It includes an integrated watchdog timer and power-fail detection capabilities. The reset delay time is specified at 610 ms, with an accuracy of 10%. Operating current is 200 uA. The component is housed in a SOIC-Wide-16 package and supports surface mount installation. It functions reliably across a temperature range from -40 C to +85 C.

Supervisors Procurement Notes

Verify the specific suffix T&R indicates reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc./Maxim Integrated to ensure authenticity. Check RoHS compliance details against current regulatory requirements. Validate the SOIC-Wide-16 package dimensions against your PCB footprint specifications. Ensure the operating temperature range meets your environmental design constraints.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with watchdog functionality is required. Consider the 200 uA operating current for low-power applications. Verify that the 610 ms reset delay aligns with your system startup timing requirements. Ensure the 3.3 V to 5.5 V input range covers your nominal supply voltage. The wide operating temperature range suits harsh environments.
