300 mA, dual-channel antenna LDO with current sensing
The NEX92x30-Q100 devices are dual-channel, high-voltage 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 mA 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-to-digital converter (ADC) resources. Each channel also implements adjustable current limits with an external resistor. Figure 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.

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
