BCT7915H
Over-Voltage Protection Load Switch
BCT7915H
Over-Voltage Protection Load Switch
GENERAL DESCRIPTION
The BCT7915H OVP load switch features surge protection, an internal clamp circuit protects the device from surge voltages up to 100V.
The BCT7915H features an ultra-low 30.7m (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 6.8V, the OVP threshold can be adjusted from 4V to 20V through external OVLO pin.
The device features an open-drain output ACOK,when VIN_UVLO < VIN < VIN_OVLO and the switch is on,ACOK 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.
The BCT7915H is available in a RoHS compliant 1.8mm × 1.3mm FCQFN1.8X1.3-12L package.
