Dual 1 Form A Solid-State Relay

DESCRIPTION

The LH1526 relay are two SPST normally open switches

that can replace electromechanical relays in many

applications. The relays require a minimal amount of LED

drive current to operate, making it ideal for battery powered

and power consumption sensitive applications. The relay

is constructed using a GaAIAs LED for actuation control

and an integrated monolithic die for the switch output.

The die is, fabricated in a high-voltage dielectrically

isolated technology, comprised of a photodiode array,

switch-control circuitry, and MOSFET switches. In addition,

the relay employs current-limiting circuitry, enabling it to

pass lightning surge testing as per ANSI/TIA-968-B and

other regulatory surge requirements when overvoltage

protection is provided. The relay can be configured for

AC/DC or DC-only operation.

FEATURES

• Dual channel 1 form A

• Extremely low operating current

• High speed operation

• Isolation test voltage 5300 V

RMS

• Current limit protection

• High surge capability

• DC only option

• Clean bounce free switching

• Low power consumption

• High reliability monolithic receptor

• Surface mountable

• Compliant to RoHS Directive 2002/95/EC and in

accordance to WEEE 2002/96/EC

APPLICATIONS

• General telecom switching

- Telephone line interface

- On/off hook

- Ring relay

- Break switch

- Ground start

• Battery powered switch applications

• Industrial controls

- Microprocessor control of solenoids, lights, motors,

heaters, etc.

• Instrumentation

Note

• See “solid-state relays” (application note 56)

Notes

• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not

implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute

maximum ratings for extended periods of the time can adversely affect reliability.

(1)

Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through

hole devices (DIP).

Note

• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering

evaluations. Typical values are for information only and are not part of the testing requirements.
