1.4 Device Information

The TPS7B780x-Q1 family of devices are single-channel (TPS7B7801Q1) or dual-channel (TPS7B7802Q1), high voltage low-dropout regulators with an integrated ADCs and I2C interfaces. The family of devices has a wide input voltage operating range, and is designed to protect against a 45V input voltage load dump scenarios. They are an excellent choice to provide power to remotely located low-noise amplifiers (LNAs) associated with FM/DAB/GNSS antennas, microphones, and camera modules over coaxial cables in an automotive environment. Each channel can provide up to 300mA of output current and an adjustable output voltage from 2V to 40V configured either via external resistors or over I2C.

The integrated 10-bit ADC allows the user to continuously monitor the input voltage, output voltage, junction temperature and load current. The high accuracy current sense circuitry across the current range allows this device to detect and distinguish between open, normal, and short-circuit conditions without further calibration. Each channel also offers adjustable current limit that can be set via I2C communication.
