SC728/SC729
2A Low Vin, Very Low Ron Load Switch
Description
The SC728/SC729 is a low input voltage, very low Ron load switch designed for use in battery powered applications. 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.
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.
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.
