The MAX16948 is a dual high-voltage, current-sensing low dropout linear regulator (LDO)/switch designed to operate with an input voltage range from 4.5V to 28V (45V load dump tolerant). The device provides phantom power over coax cable to remote radio frequency low-noise amplifiers (LNAs) in automotive systems with a maximum current of 300mA per channel. The device also provides a fixed regulated output voltage of 8.5V or an adjustable 1V to 12.5V output voltage. The device can also be configured as a switch.The device monitors the load current and provides an analog output current proportional to the sensed load current.

The device features an open-drain error output for each channel to indicate to the microcontroller (µC) when a fault has occurred.The device features short-to-battery protection to latch off the internal LDO/switch during a short-to-battery event. During a thermal overload, the device reduces power dissipation by going into thermal shutdown. It includes two independent active-low, high-voltage-compatible shutdown inputs to place each channel in a low-power shutdown mode.The device is available in a 16-pin TQFN package with exposed pad, a 16-pin QSOP package with exposed pad, or a 16-pin QSOP package and is fully specified over the -40°C to +105°C temperature range.ApplicationsAutomotive Camera and Sensor PowerRemote LNA Phantom Power
