YB1900C
Ultra Low Quiescent Current Smart Load Switch
Description
The YB1900C is a high side slew rate
controlled smart load switch. The slew rate
control in YB1900C can effectively avoid
the large in-rush current which is
commonly observed in normal power
switches. Moreover, the level shift in
YB1900C allows customers to control 1.8
to 5.5V system with 1.5V logic and without
sacrificing leakage current.
The YB1900C has typical low RDS(on)
around 100mΩ, which allows large power
handling capabilities. Very low quiescent
current and fast load discharge also makes
it ideal for power sensitive applications
nowadays.
The YB1900C is available in SOT23-5 or
SOT23-6 package with the temperature
range valid from -40 to 85℃.
