Product Brief ANX7437 is an intelligent crosspoint switch that supports switching at data rates of up to 10Gbps. ANX7437 supports highspeed interfaces, such as USB 3.1 (Gen 1 - 5Gbps, Gen 2 - 10Gbps). ANX7437 is designed as a companion IC to various CPUs and Application Processors (APs) to enable notebooks, desktops, and 2-in-1 PCs to use the reversible USB Type-C (USB-C™) connectors. An On-chip Microcontroller (OCM) is available to manage the signal switching, Channel Configuration (CC) detection, USB Power Delivery (USB-PD) charging and Vendor Defined Message (VDM) protocol, and other functions, as defined in the USB Type-C v1.2 and USB Power Delivery v3.0 specifications. ANX7437 can be configured for a Downstream Facing Port (DFP) or Dual-Role Port (DRP) to support a USB-C receptacle. • USB 3.1 signal (SSTX and SSRX) with Gen1 (5Gbps) and Gen2 (10Gbps) link speed • Native TCPC-compliant hardware register interface • Supports DFP and DRP modes for Host-only or DualRole applications • Integrated VCONN FETs • Built-in 10-bit ADC to monitor VBUS voltage and current • Dedicated control signals for VBUS Source FET, VBUS sink FET, and VBUS auto discharge circuity • Serial and debug interfaces - Slave interface - Direct Connect Interface (DCI) debug support • Industry standard compatibility - USB Power Delivery v3.0 r1.0 specification - Universal Serial Bus (USB) Type-C Port Controller Interface r1.0 specification • Low-power design - Dedicated supply power pin for flexible I/O power 1.8V or 3.3V - Ultra-low power consumption (typical 80uW) in standby mode • On-chip Microcontroller (OCM) to implement signal switching and USB-PD messaging - 64K bytes SRAM for firmware execution - 128K bytes Flash for firmware storage - PDFU function for firmware updating • Dead battery detection support • Package offered: 48-pin QFN, 6mm x 6mm, 0.90mm Z-height, pin-pitch: 0.4mm
