Charger Reference Design Takes on Challenging Battery Systems
The PMP41115 integrated 240-W USB Type-C and USB PD3.1 charger reference design developed by Texas Instruments integrates USB Type-C and USB power delivery for 10 to 12 cell batteries for applications such as e-bikes, high-capacity power banks, and portable power-station applications.
The design leverages the company’s TPS26750 and TPD4S480 USB PD3.1 controllers with a 48-V extended power range USB port protector.Also incorporated is the BQ25756 four-switch buck boost controller for USB PD3.1 functionality at 240 W.
The PD controller talks to the charger controller through I2C, and the BQ25756 accepts a wide-range input with four-switch buck-boost configuration. Coupled with seamless transition from buck, boost, and buck-boost operation mode, it forms a highly efficient, highly accurate, and reliable charger design featuring 48-V short-to-VBUS, overvoltage, and electrostatic discharge (ESD) protection, operating at 97.6% full load efficiency.
