What are the key features of TPS3619-50DGKG4?
- Fixed 5.0 V supply-voltage threshold with manual reset input for reliable microcontroller and SRAM power supervision
- Battery-backup switching architecture maintains RAM retention during power loss without external discrete components
- Compact 8-pin TSSOP (TSSOP8 .19) package minimizes PCB footprint in space-constrained embedded designs
What is TPS3619-50DGKG4 used for?
The TPS3619-50DGKG4 is designed for industrial controllers, PLC modules, and battery-backed SRAM systems that require reliable supply monitoring at 5 V rails. When main power drops below the 5.0 V threshold, the device seamlessly switches to a backup battery to preserve RAM contents, making it essential in meters, data loggers, and real-time clock circuits. Its manual reset input allows system-level initialization control during power-on or fault recovery sequences.

Frequently Asked Questions
Which designs can use TPS3619-50DGKG4 when 8 pins is a required parameter?
TPS3619-50DGKG4 is a practical fit when the design needs 8 pins in a integrated circuit from Texas Instruments. Buyers should confirm the package, lifecycle state, and original datasheet before approving it for production builds.
How should buyers compare TPS3619-50DGKG4 with alternate integrated circuit options?
Use -40°C to 85°C as one verified requirement, then match the electrical ratings, footprint, and manufacturer series against the target BOM. This reduces substitution risk when similar parts differ in assembly or operating limits.
Which assembly detail should be checked before sourcing TPS3619-50DGKG4 for production?
Confirm that the selected lot matches MSOP and the known 5.0 V requirement before RFQ approval. This gives incoming inspection and engineering teams a clearer basis for footprint, mating, or thermal review.
