New Fault Protection Switch From Supertex Includes Current Fold-Back to Save Downstream Circuitry

Supertex (NASDAQ: SUPX), a recognized leader in high voltage analog
and mixed signal integrated circuits (ICs), today introduced
FP0100, a fault protection switch with current fold-back that
guards against over-current or short circuit conditions in system's
output power supplies. The switch is suited for applications in
which downstream circuit protection is needed, such as high side
switches, instrumentation, and data acquisition. FP0100 is the
first in a family of fault protection devices Supertex plans to
introduce.
FP0100 features a low on resistance of 4.0 ohms typical. The
peak current allowed to pass through the switch is set by an
external resistor, programmable to 260mA. In its off state, the
switch can withstand input voltages up to 100V.
"The FP0100's response time to a fault is less than 1
microsecond, and it automatically recovers after fault conditions.
Supertex is excited to enter into the fault protection market with
this innovative approach that offers high speed and automatic
recovery for applications that depend on downstream circuit
protection," states Hernan DeGuzman, Vice President of Marketing
for Supertex. "FP0100 can withstand input voltage of 100V by
itself, or can be combined with a MOSFET, such as Supertex DN3545,
to withstand inputs up to 450V."
The FP0100 is available in a SOT-89 package (FP0100N8-G). The
part is RoHS compliant. Samples are available from stock. Lead-time
for production quantities is 4-6 weeks ARO. Pricing is US$0.95 each
for the FP0100N8-G in 1K quantities.
