AOZ1320
Load Switch with Controlled Slew Rate
General Description
The AOZ1320 is a P-channel high-side load switch with
controlled slew rate. Three slew rate options are
available. The AOZ1320-01 and AOZ1320-04 have a
slew rate of 1ms, and the AOZ1320-07 has a slew rate of
4.5ms. The AOZ1320-02 and AOZ1320-05 feature fast
Slew Rate (less than 500ns). The slew rate of
AOZ1320-03 and AOZ1320-06 is 100µs. The
AOZ1320-03, AOZ1320-04, AOZ1320-05, and
AOZ1320-07 provide an output discharge circuit to
quickly discharge the output when the switch is disabled.
The P-channel MOSFET has typical on resistance of
75m¾. The very low R
DS(ON)
significantly reduces the
power path dissipation. The input voltage range of
AOZ1320 is from 1.8V to 5.5V. The control input is
compatible with both TTL and CMOS logic. Ultra low
quiescent current makes this product suitable for any
portable applications.
The AOZ1320 is available in a 6-pin SOT23 or
8-pin 2mm X 2mm DFN package and is rated over
the -40°C to +85°C ambient temperature range.
