HUSB332B_U31DA

HUSB332B is a USB Type-C electronically marked chip for cable identification applications. It complies with USB Type-C Specification Revision 2.1, as well as USB Power Delivery 3.1 and USB4™ specifications. The chip draws power from the VCONN1 or VCONN2 pin and is capable of determining its role as an SOP' device. Its built-in OTP can be programmed via the CC line or I²C bus, providing flexibility for in-system programming. HUSB332B implements an encrypted instruction set that enables it to respond to hosts or devices in an encrypted manner, facilitating mutual identification before the system enters any mode. The chip operates over a wide voltage range of 2.7 V to 5.75 V, is available in DFN2×2-6L and WLCSP-6B packages, and is rated for an operating temperature range of -40 °C to +85 °C.
