PTN5110

PTN5110 USB PD TCPC PHY IC Rev. 1.6 — 3 April 2020 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 I2C-bus interface registers...
