USB Power Delivery and Advanced Protocol Controller

  HL9801 Main Photo


The HL9801 is highly integrated, secondary-side power adaptor controller compatible with various protocols.

The HL9801 supports constant voltage (CV) and constant current (CC) regulations with internal operational error amplifiers. In addition, it implements various adaptive output protections, such as under-voltage protection, over-voltage protection, over-current protection, as well as internal/external over-temperature protections.

The HL9801 can be designed as a source only USB type-C controller which is optimized for mobile chargers and power adapters. The N-channel MOSFET is compatible as a load switch and helps to reduce BOM cost.
