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; AEC−Q101 Qualified and
PPAP Capable
These are Pb−Free 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
Pre−conditioning of Voltage Regulator Input Voltage
