ISL15102

Single Port, PLC Differential Line Driver

Product Status: Mass Production

OVERVIEW

The ISL15102 is a single port differential line driver developed for Power Line Communication (PLC) applications. The device is designed to drive heavy line loads while maintaining a high level of linearity required in Orthogonal Frequency Division Multiplexing (OFDM) PLC modem links.

The ISL15102 has a disable control pin (DIS). In Disable mode, the line driver goes into Low Power mode and the outputs maintain a high impedance in the presence of high receive signal amplitude, improving TDM receive signal integrity.
The ISL15102 has built-in thermal protection. When the internal temperature reaches +150°C (typical) the driver shuts down to prevent damage to the device.

An internal input CM buffer maximizes the dynamic range and reduces the number of external components in the application circuit.

The ISL15102 is supplied in a thermally-enhanced small footprint (4mmx5mm) 24 Ld QFN package. The ISL15102 is specified for operation across the -40°C to +85°C operating ambient temperature range.
