DESCRIPTION
TheVN02N is a monolithic device made using SGS-THOMSON
Vertical Intelligent Power Technology, intended for driving resistive or inductive loads with one side grounded.
Built-in thermalshut-down protects the chip from overtemperature and short circuit.The input control is5V logic level compatible.
The open drain diagnostic output indicates open circuit (noload) and over temperature status.
