Product data sheet
1. General description
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:
1. Provider (P)
2. Provider/Consumer (P/C)
3. Consumer (C)
4. 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 I

C-bus
interface registers, finite state machines and control flow, etc. as defined in [3]. Please
refer to [3] for description of I
2
C 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:
1. PTN5110 provides independently controllable pull-up resistor (Rp) implementations
on CC1 and CC2 pins.
2. PTN5110 can detect/monitor voltage levels independently on each CC pin.
2. Features and benefits
2.1 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)
Supports VBUS source/sink power path control
Supports Seamless VBUS source voltage transitions among PD voltage rails (e.g.
using Load switches - 5 V VBUS source switch - NX5P3290, High Voltage VBUS
source switch):
- For positive voltage transitions, PTN5110 implements make-before-break feature
(turn on higher voltage rail first and turn off lower voltage rail after a programmable
time duration determined by summation of turn-on time and enable time of higher
voltage rail load switch).
- For negative voltage transitions, PTN5110 disables higher voltage rail load switch
initially, performs force discharge and monitors VBUS voltage until stop threshold is
reached and enables lower voltage rail load switch when VBUS voltage reaches
equal to (or slightly less than) the programmed rail voltage in the TCPC I
