説明
- PMP4425, Reference Design provides detailed data for evaluating and verifying a USB charger, which uses a USB charge controller, a buck converter and a shunt amplifier. Additionally the design demonstrates an automotive USB charging port that offers short-to-battery protection. With the help of the shunt amplifier, the design is capable of compensating for the effects on Vdroop when a SmartPhone/tablet is connected to the USB charger using a cable that is roughly 2-3 meters in length. Compliance with almost all major SmartPhone/tablet manufacturers is supported due to programmable current limit up to 2.1 A, BC 1.2 compliant devices are supported as well as D+/D- divider modes of 2.7V/2.7V and 1.2V
