Description
AW32105E and AW32105P are high input voltage, large current and ultra-low Ron load switch with soft-start, over voltage protection, over current protection, over temperature protection, short circuit protection. AW32105E has reverse current blocking, and AW32105P has OTG function. They are optimized to protect systems with USB Type-C PD ports that sink up to 100W at 20V and withstand up to 31VDC on VBUS.
AW32105E has all time Reverse Current Protection regardless of the EN logic level. When disabled, all current flow is blocked. AW32015E has automatic reverse-current blocking feature which acts as an “ideal diode” and isolates VBUS when charging or powering the system via another port. Once the voltage on OUT is higher than IN for RCP trigger voltage, the RCP circuit disables the power switch. Two AW32105E chips can be used in parallel to support dual power inputs connecting to the same charging circuit.
AW32105E and AW32105P are turned off very fast once the input voltage exceeds the OVP threshold to prevent damage to the protected downstream devices. The IN pin is capable of withstanding fault voltages to 31VDC. AW32105E and AW32105P provide a default OVP threshold of 24V typical, and the OVP threshold can be adjusted from 4V to 24V through external OVLO pin.
