Slew-rate control and load discharge
The MIC94045YFL-TR: Two integrated features address common power-sequencing problems. The slew-rate controlled turn-on limits inrush current into capacitive loads — a 10 µF output capacitor sees a controlled ramp rather than a current spike that could droop the input rail. The load-discharge feature pulls the output to ground when the switch is turned off, preventing a floating output that could hold a downstream load in an undefined state. The 4-MLF (1.2x1.2 mm) package with a 0.50 mm pitch demands a controlled solder profile but delivers a footprint under 2 mm² for space-constrained PCBs.
ROHS3 compliant per, with no halogen or lead restrictions blocking EU or North American builds. The part is supplied on Tape & Reel (full reel) or Cut Tape for prototype quantities, both through the same supply channel. No Vcc supply rail is required — the switch is self-powered from the load voltage, simplifying the BOM by eliminating a bias supply.
