The TPS7B770x-Q1 family of devices is a single and dual high-voltage LDO with current sensing designed to operate with a wide input-voltage range from 4.5 to 40 V (45-V load dump protection). The device provides 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 to 20 V.
●The device provides 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. 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 ADC resources. Each channel also implements adjustable current limit with an external resistor.
●The integrated reverse polarity diode eliminates the need for an external diode. The device features 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. The device operates during –40°C to 125°C ambient temperature range.
