PTN5110 USB PD TCPC PHY IC Product data sheet
●PTN5110 is a single-port TCPC compliant USB Power Delivery (PD) PHY IC that implements Type-C Configuration Channel (CC) interface and USB PD Physical layer functions to a Type-C Port Manager (TCPM) that handles PD Policy management. It is designed to comply with USB PD [1], Type-C [2] and TCPC [3] specifications. This IC is targeted primarily for use in system platforms (e.g. Notebook PCs, Desktop PCs, Chromebooks, Tablets, Convertibles, etc.). Other use cases may be feasible depending on the application architecture, e.g. docks, monitors, accessories, cable adapters, smartphones etc.
●It can support various Type-C roles: Sink, Source, Sink with accessory support or DRP. It implements Type-C CC analog portion (i.e Rd/Rp/Ra detection, Rd/Rp indication) and PD Tx/Rx PHY and protocol state machines as per [3]. PTN5110 supports TCPM in system realization of the following PD roles:
■ Provider (P)
■ Provider/Consumer (P/C)
■ Consumer (C)
■ Consumer/Provider (C/P)
●PTN5110 integrates VCONN load switch with programmable current limit, reverse leakage current blocking and Over Temperature Protection (OTP). It implements two enable control outputs for controlling load switches/FETs on VBUS source and/or sink power paths. It also implements VBUS voltage monitoring/measurement, VBUS Force discharge and Bleed discharge features as defined in [3]. PTN5110 implements I2C-bus interface registers, finite state machines and control flow, etc. as defined in [3]. Please refer to [3] for description of I2C registers, control descriptions, flow diagrams, etc.
PTN5110 provides the majority of relevant IO capability for the host processor/TCPM to easily control and manage the Type-C/PD interface via the TCPC interface:
■VBUS Power path control of source and sink power rails (EN_SRC, EN_SNK1)
■Up to four different slave addresses can be selected based on SLV_ADDR
■ILIM_5V_VBUS that allows TCPM to set two different current limits on VBUS 5 V Load switch.
■FRS_EN that allows for arming 5 V SRC load switch for Fast Role Swap (FRS) support
■DBG_ACC that can be used by host TCPM indicate Type-C debug accessory detection
PTN5110 offers tremendous flexibility to platform integrators by supporting a wide range of power supply input voltages. PTN5110 is available in HX2QFN16, 2.6 mm x 2.6 mm x 0.35 mm, 0.4 mm pitch.
●Remark:
■ PTN5110 provides independently controllable pull-up resistor (Rp) implementations on CC1 and CC2 pins.
■ PTN5110 can detect/monitor voltage levels independently on each CC pin.
●Features and benefits
■USB PD and Type-C features
▲Designed to comply with USB PD[1], USB Type-C [2] and TCPC [3] specifications
▲Supports Type-C functionality as per [2][3]
◆Provides CC analog functions: Rp and Rd/GND dynamic indication and Rp/Rd/Ra dynamic detection, debouncing of CC pins, dynamic selection of different Rp/Rd values for CC1 and CC2 independently ◆Implements SNK role pull-down (Rd) behavior to handle dead battery/no power condition
◆Support for Type-C Debug Accessory detection and orientation detection (refer to Appendix of [2]) for Source and Sink Target Systems (TS). Indication of the result via dedicated pin (DBG_ACC) and status registers.
◆Plug orientation detection and indication via status register(s)
◆Supports integrated VCONN switch(es) delivering power to accessory
▲Cooperatively work under TCPM control for Type-C Connection/Disconnection Detection, Power Delivery negotiation and contract(s), Alternate mode support, VDM exchanges and any custom functions
◆Implements TCPC functionality as per [3]
◆SOP* Configurable: Register programmable to generate and receive SOP, SOP’, SOP’-debug, SOP”, SOP”-debug”
◆Supports Extended messaging Unchunked and Chunked based packet transport
◆VBUS Bleed and Force discharge schemes are implemented as per [3]
◆Implements VCONN discharge on Hard Reset (TCPM Controlled)
◆ Implements Fast Role Swap request detection (in 'initial sink' role) and indication (in 'initial source' role)
