SiP32411
Vishay Siliconix
2 A, 1.2 V, Slew Rate Controlled Load Switch
DESCRIPTION
The SiP32411 is a slew rate controlled load switch that is
designed for 1.1 V to 5.5 V operation.
The device guarantees low switch on-resistance at 1.2 V
input. It features a controlled soft-on slew rate of typical
150 µs that limits the inrush current for designs of capacitive
load or noise sensitive loads.
The device features a low voltage control logic interface
(On/Off interface) that can interface with low voltage digital
control without extra level shifting circuit. It also integrates an
output discharge switch that enables fast shutdown load
discharge. When the switch is off, it provides the reverse
blocking to prevent high current flowing into the power
source.
The SiP32411DN is in TDFN4 package of 1.2 mm by 1.6 mm.
It supports over 2 A of continuous current. The SiP32411DR
is in SC70-6 package.
