Technical Specifications

The RT9737WSC features robust over-current protection, preventing excessive current flow that could damage USB ports or connected devices. The over-voltage protection prevents damage from voltage spikes. The short-circuit protection immediately shuts down the switch in the event of a short circuit. The thermal shutdown feature protects the device from overheating. The low on-resistance minimizes power loss and voltage drop across the switch. The reverse blocking protection prevents current from flowing backward into the power supply. The device typically operates at 5V. It is available in a small SOP package.
