Details
For single channel designs in short-loop VoIP applications, the LE9541DUQCT offers a comprehensive solution for battery feed, ringing, and supervision on voice loops. This SLIC device is optimized to work seamlessly with the Broadcom BCM3383/84/85/90 cable SoCs and BCM6818/28/38 PON SoCs. Its independent operation from a single, user-adjusted battery and a +3.3V VCC ensures reliable performance and versatile functionality, including forward and reverse battery feed, voice transmission, power ringing, ultra low-power scan state, ground start (Tip open), and disconnect state. The integrated test load switch further enhances its capabilities, making it an indispensable component for voice communication systems
