Description

The AW32105 is a high input voltage, large current ａｎｄ ultra-low Ron load switch bidirectional blocking. The AW32105 is 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 29VDC. The AW32105 provides a default OVP threshold of 23V typical, ａｎｄ the OVP threshold can be adjusted from 4V to 24V through external OVLO pin. The AW32105 has all time Reverse Current Protection regardless of the ENB logic level. Once the voltage on OUT is higher than ＩＮ for RCP trigger voltage, the RCP circuit disables the power switch. Two AW32105 chips can be used ｉｎ parallel to support dual power inputs connecting to the same charging circuit. The AW32105 OVP load switch features surge protection, an internal clamp circuit protects the device from surge voltages up to +/-100V. It also features over-temperature protection that prevents itself from thermal damaging.
