Telecom Switch 1 Form A Solid-State Relay
DESCRIPTION
The LH1529A and LH1529B telecom switches consist of an
optically coupled solid state relay (SSR) and bidirectional
input optocoupler. The SSR is ideal for performing switch
hook and dial-pulse switching whilst optocoupler performs
ring detection and loop current sensing functions. Both the
SSR and optocoupler have an isolation test voltage of
5300 VRMS.
FEATURES
• Solid state relay and optocoupler in one
package
• Surface mount package
• l/O isolation, 5300 VRMS
• LH1529A, CTR Min. = 33 %
• LH1529B, CTR Min. = 100 %
• Optocoupler
- Bidirectional current detection
• Solid-state relay (equivalent to TS117P)
- Typical RON 20
- Load voltage 350 V
- Load current 120 mA
- Current limit protection
- High surge capability
- Clean bounce free switching
- Low power consumption
- High reliability monolithic receptor
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• General telecom switching
- On/off hook control
- Dial pulse
- Ring current detection
- Loop current sensing
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
