MICROCHIP ZL88801LDG1

The ZL88801 Dual Channel Shared Battery Wideband VoicePort Device provides complete BORSCHT functions for two telephone line FXS ports. This device is a part of the new ZL880 Series featuring enhanced functionality, lower BOM cost, and greater power efficiency. The ZL880 Series maintains software compatibility with the industry leading VE880 Series. The ZL88801 uses energy efficient shared power supply topologies for reduced BOM cost. The ZL88801 can be configured for patent-pending inverting BuckBoost Automatic Battery Switching or Shared Tracking Battery operation.
