DESCRIPTION

The SiP4280 is a P–channel MOSFET power switch designed

for high–side load switching applications. The output pass

transistor is a P–channel MOSFET transistor with typically 80

mΩ R_DS(ON). The SiP4280 is available in two different versions

of turn–on times. The SiP4280–1 version has a slew rate

limited turn–on time typically of 1 ms. The SiP4280–3 version

has a slew rate limited turn–on time typically of 100 ꢀs and

additionally offers a shutdown load discharge circuit to rapidly

turn off a load circuit when the switch is disabled.

input undervoltage condition exists. Input logic levels are TTL

and 2.5 volt to 5.0 volt CMOS compatible. The quiescent

supply current is very low, typically 2.5 ꢀ A. In shutdown mode,

the supply current decreases to less than 1.0 ꢀ A.

The SiP4280 is available in a 8 pin SC70JW package and is

specified over –40 _C to 85 _C temperature range.

Both SiP4280 load switch versions operate with an input

voltage ranging from 1.8 V to 5.5 V, making them ideal for both

3 V and 5 V applications. The SiP4280 also features an

under–voltage lock out which turns the switch off when an
