Features
Description
The SC704/SC705 is a low input voltage, low Ron load
switch, designed for use in battery powered applications.
Integrated circuitry controls the switch to minimize resis-
tance over a wide range of conditions.
Input Voltage Range – ꢀ.ꢀV to 3.6V
500mA Continuous Output Current
Ultra-Low Ron – 90mΩ
Automatic Output Discharge Circuit
Fast Turn-on Option With No Output Discharge
Circuit – SC704
Extended Soft Start Option With Automatic Out-
put Discharge Circuit – SC705
The device provides controlled soft-start to limit inrush
current. The SC705 features an automatic discharge circuit
which discharges the output when the part is disabled.
Low Shutdown Quiescent Current
Hardened ESD Protection 5kV
Package: CSP – 0.76mm × 0.76mm, 0.4mm Pitch
The SC704/SC705 is offered in an ultra-small 4-bump
0.76mm×0.76mm Chip Scale Package (CSP) which enables
very small board area implementations. The SC704/SC705
has an operating temperature range of -40°C to +85°C.
