Applications

General telecom switching

- On/off hook switching

- Dial pulse

- Ring current detection

- Loop current sensing 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 VRMS of

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
