FP0060
General Description
The Supertex FP0060 is a low voltage AC switch with current
fold-back protection. It is designed to be used as an AC low side
switch.
The FP0060 has a maximum switch resistance of 5.0Ω. The
switch can be controlled by an enable pin, EN. The enable pin is
designed for 12V CMOS logic input. When EN is low, the switch
is open. When EN is high, the switch is closed. In the open state,
the device can withstand up to ±60V. This enables users to
control 24VAC lines with 12V logic.
The FP0060 has built-in current fold-back. If the load is shorted,
the FP0060 will detect a high current condition and will quickly
turn-off the switch. The switch will automatically turn back on
when the short is removed.
The FP0060 does not have a DC power supply pin. It operates
from the EN pin. This allows the device to be packaged in an
economical 3-pin SOT-89 package.
