Reverse blocking load switch is energy-efficient for consumer goods

Launched at APEC Power Conference, the SC33020H load switch is just 0.9 x 0.9mm and housed in a four-bump CSP (chip scale package) and what the company describes as industry leading Ron of just 32m‡.

The load switch provides power rail control for up to 2A with reverse current blocking protection for both portable and non-portable devices, including wearables, action video cameras, smartphones and tablets.
The switch accepts 1.6 to 5.5V supply input rail and whenever the output voltage goes higher than the input rail the switch blocks current from flowing in reverse direction to protect sensitive upstream circuitry or to prevent excessive power leakage loss in application standby states.  The reverse blocking feature is present at all times regardless of the switch on/off state.  The load switch is ESD-hardened to greater than 4kV for robust circuit protection.
