FP0060 Datasheet, PDF (4/5 Pages) Supertex, Inc – ±60V AC Switch with Current Fold-Back Protection

Waveform: Solenoid not shorted
Waveform: Solenoid shorted
FP0060
Channel 1: EN signal 0 to 12V logic input
turning the solenoid on and off.
Channel 2: Voltage on ACIN pin. When off,
the full AC voltage is seen on ACIN. When
on, only about 2V drop due to IR drops.
Channel 3: Voltage across a 1.0Ω resistor.
Sees the expected pull-in current of 700mA
then 400mA peaks.
Enable from low to high into
a shorted solenoid.
Peak currents of about ±1.0A.
See inductive boosting action
due to FP0060 turning off.
