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
