NCP3712ASN,
SZNCP3712ASN
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
⢠SZ Prefix for Automotive and Other Applications Requiring Unique
Site and Control Change Requirements; AECâQ101 Qualified and
PPAP Capable
⢠These are PbâFree Devices
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
⢠Preâconditioning of Voltage Regulator Input Voltage
