Frequently Asked Questions
What is the reset threshold voltage of the LM809M3-4.63?
The LM809M3-4.63 has a fixed reset threshold voltage of 4.63V. When the supply voltage drops below this level, the active-low reset output is asserted to hold the microprocessor in reset, preventing erratic operation during power fluctuations.
What package does the LM809M3-4.63 come in and what are its dimensions?
The LM809M3-4.63 is available in a 3-pin SOT-23 (JESD-30 code R-PDSO-G3, equivalent TO-236) surface-mount package. This compact package is designed for space-constrained PCB layouts in portable and embedded applications.
What are the typical applications for the LM809M3-4.63?
The LM809M3-4.63 is commonly used as a voltage supervisor and reset controller in microprocessor systems, embedded controllers, industrial automation equipment, and consumer electronics. It ensures clean power-on reset and detects supply brown-out conditions on a 4.63V rail.
Is the LM809M3-4.63 RoHS compliant?
According to Texas Instruments specifications, the LM809M3-4.63 is marked with Pbfree Code 'No' and JESD-609 Code 'e0', indicating it uses a non-lead-free finish. Buyers should verify RoHS compliance requirements and check for available lead-free alternatives such as the LM809M3X-4.63 if needed.
