Integrated Load Switch
Features
Max r DS(on) = 0.5 ? at V GS = 4.5 V, I D = –0.83 A
Max r DS(on) = 0.7 ? at V GS = 2.5 V, I D = –0.70 A
Max r DS(on) = 1.2 ? at V GS = 1.8 V, I D = –0.43 A
Max r DS(on) = 1.8 ? at V GS = 1.5 V, I D = –0.36 A
Control MOSFET (Q1) includes Zener protection for ESD
ruggedness (>4 kV Human body model)
High performance trench technology for extremely low r DS(on)
Compact industry standard SC89-6 surface mount package
RoHS Compliant
General Description
This device is particularly suited for compact power
management in portable electronic equipment where 2.5 V to
8 V input and 0.83 A output current capability are needed. This
load switch integrates a small N-Channel power MOSFET (Q1)
that drives a large P-Channel power MOSFET (Q2) in one tiny
SC89-6 package.
