TS1900

Ultra Low Quiescent Current Smart Load Switch

1/5

Version: A07

SOT-25

General Description

TS1900 is a high side slew rate controlled smart load switch. The slew rate control in TS1900 can effectively avoid the

large in-rush current which is commonly observed in normal power switches. Moreover, the level shift in TS1900

allows customers to control 1.8 to 6.5V system with 1.5V logic and without sacrificing leakage current.

and fast load discharge make it ideal for power sensitive applications nowadays.
