The UNI-SEMI U321 PMIC SOP-8 RoHS is a specialized power management integrated circuit (PMIC) featuring eight leads in a small outline package (SOP-8). It is designed to stabilize power delivery so that components can work more efficiently, while providing protection against over-currents, over-voltages, short circuits, and abnormal temperatures. The U321 works through integrated voltage regulators, voltage reference circuits, a power-on reset circuit, and a fault detection circuit. It is compliant with the Restriction of Hazardous Substance (RoHS) directive and is perfect for home appliances, industrial control, and medical equipment.
