AW32915FCR中文资料Over-Voltage Protection Load Switch with Surge Protection数据手册Awinic规格书

描述 Description

The AW3291X family OVP load switch features surge protection, an internal clamp circuit protects the device from surge voltages up to 100V.
The AW3291X features an ultra-low 27m (typ.) Rdson nFET load switch. When input voltage exceeds the OVP threshold, the switch is turned off very fast to prevent damage to the protected downstream devices. The IN pin is capable of withstanding fault voltages up to 29VDC.
The default OVP threshold is 5.95V (AW32911), 6.8V (AW32915) and 12.1V (AW32918), the OVP threshold can be adjusted from 4V to 24V through external OVLO pin.
The device features an open-drain output , when VIN_UVLO < VIN < VIN_OVLO and the switch is on,will be driven low to indicate a good power input, otherwise it is high impedance.
This device features over-temperature protection that prevents itself from thermal damaging.
