The TPS7B7702QPWPRQ1 operates over an ambient temperature range of –40°C to +125°C. Available in a 16-pin SSOP package for easy shipping, and payment methods.

The TPS7B7702QPWPRQ1 features single and dual high voltage, low-dropout regulators (LDOs), and current sensing for operation over a wide input voltage range of 4.5V to 40V (45V). Load-throw protection). The low-noise amplifier of the active antenna is powered by a coaxial cable and the output current per channel is 300mA. Each channel also provides an adjustable output voltage of 1.5V to 20V.

The TPS7B7702QPWPRQ1 provides diagnostics via current sense and error pins. To monitor the load current, the high-side current sense circuit provides an analog output proportional to the detected load current. Accurate current sensing allows open, normal, and short circuit conditions to be detected without the need for further calibration. Current sensing can be multiplexed between channels and devices to conserve analog-to-digital converter (ADC) resources. Each channel also allows adjustable current limiting through an external resistor.

TPS7B7702QPWPRQ1 is mainly suitable for high-side power switches for low-current applications, active antenna power supplies for infotainment systems, surround-view camera power supplies, etc.
