SC728/SC729

2A Low Vin, Very Low Ron

Load Switch

POWER MANAGEMENT

Features

Description

The SC728/SC729 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 (SC728) 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 – SC728



Extended Soft Start Option With Automatic Out-

put Discharge Circuit – SC729

The SC728 provides a quick turn on time, while the SC729

provides a longer soft start to limit inrush current. The

SC729 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 – SC728

1.1V Logic Level Enable Compatible With CMOS/GPIO



Control

The SC728/SC729 is offered in an ultra-small 4-bump

0.76mm × 0.76mm Chip Scale Package (CSP) which

enables very small board area implementations. The

SC728/SC729 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 SC728/SC729. Please go to Semtech.com
