LD6935X2A313Highly Integration PD Interface Controller
The LD6935X2A313 is a USB Power Delivery (USB PD) Type-C controller on the secondary side, which is designed for USB Type-C power delivery applications such as power adapters, wall chargers, car chargers, power banks, etc.
An 8 bits MCU is embedded to handle PD protocol, policy engine, and device policy manager with built-in Bi-phase Mark Coding (BMC) for USB PD communication.
The LD6935X2A313 has enhanced electrical characteristics. The 11 bits ADC can provide higher precision protection. The integrated analog cable compensation provides more linear compensation characteristics. In addition to the enhanced electrical features, the LD6935X2A313 integrates a blocking N-MOSFET and the MOS gate driver to minimize external components.
For minimizing external components, the LD6935X2A313 also integrates cap-free LDO and optimized BMC PD communications system, which simplifies the peripheral interface circuit and cable. LD6935X2A313 is available in SOP-10, the smaller 10-pin package would possess a higher power density. It has the advantages of small size and low BOM cost in PD applications.
