YB1901 - 2.0A High-Side Power Switch

Datasheet Summary

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.

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. Features.

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.
