Product details

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.

Frequently asked questions

What is the reset timeout range for DS1232LPSN-2+T&R?

The reset timeout is adjustable or selectable via external components or pin strapping, allowing the designer to set the hold-off period to match the processor's power-up settling time.

Can DS1232LPSN-2+T&R be used with 5V microcontrollers?

Yes, the 4.37V and 4.62V thresholds are specifically intended for monitoring a 5V supply rail, making this supervisor a direct fit for 5V microcontroller and logic systems.

What is the closest pin-compatible alternative to DS1232LPSN-2+T&R?

Within the MicroMonitor™ series, the DS1232LPSN-2 (without the +T&R suffix) is functionally identical — the +T&R suffix indicates Tape & Reel packaging. The base DS1232LPSN-2 is a direct drop-in replacement.
