Add To BomTPS7B7702QPWPRQ1 General Description
The TPS7B7702QPWPRQ1 is a dual-channel high-voltage low-dropout regulator (LDO) with current sensing designed for automotive applications. It operates within a wide input voltage range from 4.5 V to 40 V, providing protection against load dump up to 45 V. This device delivers power to low-noise amplifiers of active antennas through coaxial cables, with each channel capable of supplying up to 300 mA of current. Each channel also offers an adjustable output voltage ranging from 1.5 V to 20 V.Key features of the TPS7B7702QPWPRQ1 include:1. Dual-channel configuration2. Wide input voltage range3. Load dump protection4. Adjustable output voltage per channel5. High accuracy current sensing for detecting open, normal, and short-circuit conditions6. Integrated reverse polarity protection, eliminating the need for an external diode7. Thermal shutdown, undervoltage lockout, short-circuit protection, reverse battery polarity protection, reverse-current protection, output short-to-battery protection, and output inductive load clamp for robust protection and diagnostics8. Ability to multiplex current sense between channels and devices9. 16-pin HTSSOP PowerPAD package for ease of integration and thermal management.The TPS7B7702QPWPRQ1 is qualified for automotive applications and operates over an ambient temperature range of -40°C to +125°C. It provides reliable power management for infotainment systems, surround-view cameras, and other automotive electronics requiring stable and efficient power supplies.
