DESCRIPTION
The LH1539 telecom switch consists of an optically isolated
solid state relay (SSR) form A and a bidirectional input
optocoupler in a single 8-pin package. The SSR is ideal for
switch hook and dial-pulse switching while the optocoupler
performs ring detect and loop current sensing functions.
Both the SSR and optocoupler provide 5300 V
input-to-output isolation voltage.
The SSR is integrated on a monolithic receptor die using
smart power technology. The SSR features low On
resistance, high breakdown voltage, and current-limit
circuitry that protects the relay from telephone line induced
lightning surges.
The optocoupler provides bidirectional current sensing via
two anti parallel GaAs infrared emitting diodes. Very high
current transfer ratio (CTR) is achieved by coupling to a
photodarlington transistor. This high CTR allows the user to
minimize the size of the ring detector capacitor.
