What the DS1232LPSN-2+T&R is and where it fits
The DS1232LPSN-2+T&R from Analog Devices is a Simple Reset/Power-On Reset supervisor in the MicroMonitor™ series. It monitors a single voltage rail and asserts a reset output when the supply drops below a programmed threshold, holding the reset for an adjustable timeout after the rail recovers. This is the part you drop onto a 5V microcontroller board to guarantee the processor starts cleanly after a brownout or power-up glitch.
Temperature grade and environment
Rated for -40°C to 85°C ambient, this supervisor is at home in industrial control cabinets, outdoor telecom enclosures, and factory-floor automation panels where the ambient temperature swings seasonally. The 8-SOIC package is a standard footprint that fits into existing PCB layouts without a board respin.
Lifecycle and sourcing
The DS1232LPSN-2+T&R carries an Active product status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect, so it can be specified into new production BOMs without near-term obsolescence risk.
