POWER SOLID STATE RELAY
General Features OUTPUT CURRENT (CONTINUOUS) : 2.8A DIGITAL INPUT CLAMPED AT 32V PROTECTION AGAINST: LOSS OF GROUND SHORTED LOAD AND OVER-
TEMPERATURE BUILT-IN CURRENT LIMITER UNDERVOLTAGE SHUT-DOWN OPEN DRAIN DIAGNOSTIC OUTPUT FAST DEMAGNETIZATION OF INDUCTIVE
LOADS
DescriptionThe VN540-E, VN540SP-E, VN540-12-E are
monolithic devices 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 overtemperature. The open
drain diagnostic output indicates over-
temperature conditions.
