HTSSOP16 300 m A, dual-channel antenna LDO with current sensing Rev. 1 - 1 August 2025 Product data sheet 1. General description The NEX92x30-Q100 devices are dual-channel, highvoltage low-dropout (LDO) regulators with current sensing, they are designed to operate with a wide range of voltage from 4 V to 40 V (45 V load dump protection). These devices provide power supply for low noise amplifiers with an active antenna through a coax cable with 300 m A per channel. It provides an adjustable output voltage from 1.5 V to 20 V for each channel. These devices provide diagnostics through current sensing and error pins. To monitor the load current, a high-side current-sense circuitry provides a proportional analog output to the sensed load current. Accurate current sensing allows detection of open, normal, and short-circuit conditions without the need for further calibration, and current sensing multiplexing is allowed between channels to conserve analog-todigital converter (ADC) resources. Each channel also implements adjustable current limits with an external resistor. Fig. 1 shows the typical application. The device integrates short-circuit, over-current, thermal shutdown, short-to-battery and reverse current protections. Each channel has internal inductive clamp protection on the output during inductive switch-off. It can operate at ambient temperatures ranging from -40 °C to 125 °C and junction temperatures ranging from -40 °C to 150 °C with an HTSSOP16 package.
