DESCRIPTION
The LH1546AD (4 pin DIP) is robust, ideal for telecom and
ground fault applications. It is an SPST normally open
switch (1 form A) that replaces electromechanical relays in
many applications. It is constructed using a GaAs LED for
actuation control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated BCDMOS technology, is comprised of
a photodiode array, switch control circuitry and MOSFET
switches. In addition, it employs current-limiting circuitry
which meets lightning surge testing as per ANSI/TIA-968-B
and other regulatory voltage surge requirements when
overvoltage protection is provided.
FEATURES
• Current limit protection
• Isolation test voltage 5300 V_RMS
• Typical R_ON 28 
• Load voltage 350 V
• Load current 120 mA
• High surge capability
• Clean bounce free switching
• Low power consumption
• High reliability monolithic receptor
• SMD lead available on tape and reel
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• General telecom switching
- On/off hook control
- Ring relay
- Dial pulse
- Ground start
- Ground fault protection
• Instrumentation
• Industrial controls
Note
• See “solid-state relays” (application note 56)
