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.
TS1900 has typical low R_DS(on) at 100mΩ, it allows large power handling capabilities. And very low quiescent current
and fast load discharge make it ideal for power sensitive applications nowadays.

Features
● 1.8 to 6.5V Input Voltage Range
