TPS7B7702QPWPRQ1 is a dual, high-voltage low-dropout regulator (LDO) with current sensing, designed to operate with a wide input-voltage range from 4.5 V to 40 V (45-V load dump protection).
TPS7B7702QPWPRQ1 provide power to the low-noise amplifiers of the active antenna through a coax cable with 300 mA per channel current. Each channel also provides an adjustable output voltage from 1.5 V to 20 V.
TPS7B7702QPWPRQ1 provide diagnostics through the current sense and error pins. To monitor the load current, a high-side current-sense circuitry provides a proportional analog output to the sensed load current.

TPS7B7702QPWPRQ1——The accurate current sense allows detection of open, normal, and short-circuit conditions without the need for further calibration. Current sense can be multiplexed between channels and devices to save analog-to-digital converter (ADC) resources. Each channel also implements adjustable current limit with an external resistor.
An integrated reverse polarity diode eliminates the need for an external diode. TPS7B7702QPWPRQ1 feature standard thermal shutdown, short-to-battery protection on the output, and reverse current protection. Each channel has internal inductive clamp protection on the output during inductive switch off.
TPS7B7702QPWPRQ1 operate over a –40°C to +125°C ambient temperature range.
Applications Of TPS7B7702QPWPRQ1:
Infotainment Active-Antenna Power Supplies
Surround-View Camera Power Supplies
High-Side Power Switch For Small-Current Applications
