DESCRIPTION
The VN540, VN540SP, VN540(011Y), VN540(012Y) is a monolithic device designed in STMicroelectronics VIPower technology, intended for driving resistive or inductive loads with one side connected to ground. Active current limitation avoids the system power supply dropping in case of shorted load. Built-in thermal shut down protects the chip from over temperature. The open drain diagnostic output indicates over temperature conditions.

■ OUTPUT CURRENT (CONTINUOUS): 2.8A
■ DIGITAL INPUT CLAMPED AT 32V
■ PROTECTION AGAINST: LOSS OF GROUND, SHORTED LOAD AND OVERTEMPERATURE
■ BUILT-IN CURRENT LIMITER
■ UNDER VOLTAGE SHUT DOWN
■ OPEN DRAIN DIAGNOSTIC OUTPUT
■ FAST DEMAGNETIZATION OF INDUCTIVE LOADS.
