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
•
