HUSB335

FEATURES UFCS 1.0 Protocol Compliant:  Support UART communication with Input Default State  Automatic Baud rate Tracking among 115.2 kHz, 57.6 kHz, 38.4 kHz  Autonomous Response to Get_CableInfo Message Programmable Cable Resistance, Cable Voltage and Current 2 Times for User Programming through USB Connector 3 V to 5.5 V Operating Voltage Low Operating Current: 200 μA Internal Temperature Period Update Enhance HBM ESD for Interface Pins: ±8 kV Small Package: DFN1.6 mm x 1.6 mm APPLICATIONS Cable ID for UFCS Cables TYPICAL APPLICATION CIRCUIT GENERAL DESCRIPTION HUSB335 is a Cable ID chip for a cable which could be employed for UFCS cables. It is fully compliant with the Universal fast charging specification (UFCS) for mobile devices (T/TAF 083-2022). The HUSB335 is able to respond the UFCS protocol on the D+ or D- pin, depending on the received messages. The D+ and D- pins detect the message transmitted at both lines and the HUSB335 locks the first line for the correct cable message. The built-in OTP can be programmed through D+ and D- pins so that it will be flexible for in-system programming. The enhanced ±8 kV ESD protection on the exposed pins can improve the system reliability significantly. The HUSB335 operates over a wide supply range of 3 V to 5. 5 V. It is available in DFN1.6×1.6-6L package. It is rated over the -40°C to 85°C temperature range. The operating current is as low as 200 μA.
