400mA/200mA Dual 3.3V Smart Power Switch

DESCRIPTION The SC1543 provides a glitch free 3.3V output when one of two 3.3V input sources is present. It does not require external logic to sequence from one input source to the other. Whenever VIN1 exceeds a predetermined threshold value the internal MOSFET connects it’s source voltage to the
