产品详细说明

TPS7B7701QPWPRQ1 is Texas Instruments' single-channel automotive antenna LDO in a 16-pin HTSSOP PowerPAD package, with an adjustable output and up to 300 mA available to a remote antenna load.

It regulates across a 4.5 to 40 V input range so an active antenna amplifier can receive its supply over a coaxial feed even as the vehicle battery voltage changes.

A proportional current-sense output reports antenna current to the host, allowing open, normal and short-circuit conditions to be distinguished without placing a separate monitor in the coax path.

The output voltage and current limit are set externally to match the amplifier, while reverse-polarity, reverse-current and short-to-battery protection reduce the external circuitry otherwise needed at the vehicle interface.

Its AEC-Q100 Grade 1 qualification and 16-pin thermal package make this exact option suitable for automotive antenna modules that need both supply control and fault diagnosis.
