Frequently Asked Questions
What reset threshold voltage does PTLV809EA43DBZR use, and is it adjustable?
The PTLV809EA43DBZR has a fixed reset threshold of 4.3 V with no adjustable threshold option, simplifying the design by eliminating external resistor dividers while providing a defined trip point for 5 V power rail monitoring.
What type of reset output does PTLV809EA43DBZR provide for MCU reset circuits?
The PTLV809EA43DBZR provides an active-low push-pull reset output, which can directly drive the active-low reset pin of most microcontrollers without a pull-up resistor, reducing component count in 3-pin SOT-23 supervisory designs.
How compact is the PTLV809EA43DBZR footprint and what assembly advantages does it offer?
The device uses a 3-pin SOT-23 package, one of the smallest available surface-mount outlines, enabling voltage supervision to be added to dense PCB layouts with minimal board space impact and straightforward automated SMT placement.
Is PTLV809EA43DBZR still available for procurement in new designs given its lifecycle status?
The PTLV809EA43DBZR was introduced in June 2019 and is a relatively recent 3-pin SOT-23 device, though buyers should verify current stock levels and lead times through distribution channels when planning production volumes for 5 V supervisory applications.
