Fast Charge Adapter Control Board Using MaxCharge™ Technology Reference Design

1 января 2018

The PMP40133 control board provides the interface with fast charger adapter solution. The main MCU is MSP430G2955 which controls communication with a charger device using MaxCharge™ techonlogy. TPL0102-100 digital potentiometer is used for fine tuning the adapter output voltage. 256 taps enables 10mV votlage step adjustement accuracy. INA199B current detection circuit and voltage divider circuit is used for adapter’s OCP and OVP.
