NCP3712ASNT1_06 Datasheet, PDF (1/4 Pages) ON Semiconductor – Over Voltage Protected High Side Switch

NCP3712ASNT1
Over Voltage Protected
High Side Switch
This switch is primarily intended to protect loads from transients by
isolating the load from the transient energy rather than absorbing it.
Features
• Capable of Switching Loads of up to 200 mA without External
Rboost
• Switch Shuts Off in Response to an Over Voltage Input Transient
• Features Active Turn Off for Fast Input Transient Protection
• Flexible Over Voltage Protection Threshold Set with External Zener
• Automatic Recovery after Transient Decays Below Threshold
• Withstands Input Transients up to 105 V Peak
• Guaranteed Off State with Enbl Input
• ESD Resistant in Accordance with the 2000 V Human Body Model
• Extremely Low Saturation Voltage
• Pb−Free Packages are Available
Applications Include:
• High Voltage Transient Isolation
• Power Switching to Electronic Modules
• DC Power Distribution in Line Operated Equipment
• Buffering Sensitive Circuits from Poorly Regulated Power Supplies
• Pre−conditioning of Voltage Regulator Input Voltage
