Beschreibung
- PMP9765, Automotive USB Charging Port Supply Reference Design includes a power management circuit which is capable of controlling a remote USB charging port in an automotive application environment. The circuit can be supplied directly from the car battery rail. It uses a small and highly efficient step down converter, the TPS62130A-Q1, to regulate the required USB bus voltage for charging with charge currents up to 2.5A. The USB charging port is controlled and protected by using a USB charging controller, the TPS2549-Q1, this charging controller is also used to monitor the charge current for adjusting the output voltage of the TPS62130A-Q1. This way the voltage drop across the cable connection to the USB port is compensated
