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.
