AOZ1325DI Datasheet, PDF (1/12 Pages) Alpha & Omega Semiconductors – Dual Channel Load Switch with Controlled Slew Rate

AOZ1325DI
Dual Channel Load Switch with
Controlled Slew Rate
General Description
The AOZ1325DI is a P-channel high-side load switch
with slew rates of 1ms. The AOZ1325DI provide an
output discharge circuit to quickly discharge the output
when the switch is disabled.
The P-channel MOSFET has typical on resistance of
250mΩ at 1.8V. The very low R_DS(ON) significantly
reduces the power path dissipation. The input voltage
range of AOZ1325DI is from 1.6V 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 AOZ1325DI is available in 8-pin 3x3 DFN package
and is rated over the -40°C to +85°C ambient
temperature range.
