YB1901
2.0A High-Side Power Switch with Flag
Description
The YB1901 is a low operation voltage,
single N-channel MOSFET high-side
power switch, optimized for low power
consumption system. A small internal
charge-pump circuitry is built in the
YB1901 to drive the internal MOSFET
switch for reaching an average RDS(ON)
resistance of 120mΩ. A fault flag output is
available to indicate an abnormal condition
during operation.
Some other features include low in-rush
current during plug-in, thermal shutdown to
prevent switch failure from high-current
loads, under-voltage lock-out to keep the
chip off when below normal operation
supply, a short-circuit protection to avoid
grounded big current. The quiescent
current needed to run the change-pump is
as low as 60μA at 5V input. It makes the
device ideal for portable battery operated
system.
The YB1901 power switch is available in
SOT-25, MSOP8, SOP8 packages.
