UM3865P
Load Switch with Level-Shift
UM3865P SOT363
General Description
The UM3865P includes a p- and n-channel MOSFET in a single SOT363 package. The low
on-resistance p-channel MOSFET is tailored for use as a load switch. The n-channel, with an
external resistor, can be used as a level-shift to drive the p-channel load switch. The n-channel
MOSFET has internal ESD protection and can be driven by logic signals as low as 1.5V. The
UM3865P operates on supply lines from 1.8V to 8V, and can drive loads up to 1A.
