Description: Subscriber Line Interface Circuit

Features

* 24-pin SSOP package
* High and low battery with automatic switching
* 60 mW on-hook power dissipation in active state
* On-hook transmission
* Long loop battery feed tracks Vbat for maximum line voltage
* Only +5 V feed in addition to battery

Applications

* The PBL 386 21/2 has constant current feed, programmable to max. 30 mA. A second lower battery voltage may be connected to the device to reduce short loop power dissipation. The SLIC automatically switches between the two battery supply voltages without need for external components or external cont
