LQ050 Series Load Switch

Littelfuse's LQ050 series integrated load switch ICs incorporate cutting-edge technology that achieves industry-leading performance in ultra-low-power consumption (low I_Q, ISD, and R_DS(ON)), empowering designers to curtail parasitic leakage current, enhance system efficiency, and extend the battery lifespan. The load switch ICs can control the output voltage slew rate that can limit the inrush current.

The LQ050 detects when the system output voltage is higher than the system input voltage, blocking backward current flow through the system. When the load switch IC turns off, it may be necessary for the output capacitor to discharge quickly to prevent unpredictable behavior of the downstream devices due to slow capacitor discharge. The load switch ICs are ideal for battery-charged device power-saving, power sequence control, and power MUX (PMUX) applications.
