Product details

Temperature range and deployment environment

Rated for -40°C to 85°C ambient, the DS1819AR-10+T&R is specified for industrial environments — motor drives, outdoor base stations, factory-floor PLCs, and HVAC controllers. The SOT-23-5 package keeps board area small and suits reflow assembly alongside other surface-mount passives. No special thermal management is needed at this power level; the part's own quiescent draw is negligible in the system power budget.

Lifecycle and sourcing posture

The DS1819AR-10+T&R carries an Active lifecycle status with ROHS3 compliance.

Frequently asked questions

Is DS1819AR-10+T&R compatible with 3.3V systems?

Yes — the 2.925V threshold is specifically chosen to monitor a 3.3V rail, asserting reset before the supply drops below the valid logic operating range.

What is the difference between DS1819AR-10 and DS1819AR-10+T&R?

The +T&R suffix indicates Tape & Reel packaging for automated assembly. The DS1819AR-10 base part is the same silicon; the T&R variant is the reeled version for SMT production lines.

What is the closest pin-compatible alternative to DS1819AR-10+T&R?

Within the MicroMonitor series, parts with the same SOT-23-5 footprint and active-low push-pull output but different threshold voltages (e.g., DS1819AR-5 at 4.625V for 5V rails) are pin-compatible. For the same 2.925V threshold, the DS1819AR-10 without the T&R suffix is electrically identical.
