SC724/SC725
2A Low Vin, Very Low Ron
Load Switch
POWER MANAGEMENT
Features
Description
The SC724/SC725 is a low input voltage, very low Ron
load switch designed for use in battery powered applica-
tions. Very low quiescent current of less than 2µA, and a
low shutdown current of less than 1µA (SC724) reduces
power loss during Standby and Off states. A logic level
Enable allows low voltage on/off control down to 1.1V.
Input Voltage Range – 1.1V to 3.6V
2A Continuous Output Current
Ultra-Low Ron – 36mΩ
Automatic Output Discharge Circuit
Fast Turn-on Option With No Output Discharge
Circuit – SC724
Extended Soft Start Option With Automatic Out-
put Discharge Circuit – SC725
The SC724 provides a quick turn on time, while the SC725
provides a longer soft start to limit inrush current. The
SC725 also features an automatic discharge circuit which
discharges the output when the part is disabled.
Low Quiescent Current – 0.81µA(Typ.)
Low Shutdown Current < 1µA – SC724
1.1V Logic Level Enable Compatible With CMOS/GPIO
Control
The SC724/SC725 is offered in an ultra-small 4-bump
0.76mm × 0.76mm Chip Scale Package (CSP) which
enables very small board area implementations. The
SC724/SC725 has an operating ambient temperature
range of -40°C to +85°C.
Hardened ESD Protection 3kV
Package: CSP – 0.76mm × 0.76mm, 0.4mm Pitch
SC724/SC725 offers an alternative bump connection
pattern to SC724/SC725. Please go to Semtech.com
