• NXP is adding also support for SCP direct charging protocol, Qualcomm QC4.0 universal high voltage & direct charging
protocol and other proprietary protocols Introduction
Description
• Ease of design
NXP provides total wall to battery solution with complete reference designs and local support
• Best-in-Class power density
meeting all DOE & EU-CoC Tier2 energy efficiency requirements (>91% @ 12V/2.1A or 5V/5A) & <30mW no-load
• Flexibility
multi-protocol support for USB-PD, QuickCharge, direct charging & other customized protocols and main functionality
configurable by ODM – less inventory
• Low BOM cost
low external component count due to high digital integration and support of low cost NMOS port switch & small wave
soldering packages
• Best-in-Class safety protecting phone & battery
widest set of hardware integrated protections covering up to 20 failure use cases
• Security
interface for authentication chip allowing own eco-system specific accessories and preventing use of unsafe chargers
Features
• Flexible high efficiency, safe and secure smart charging system solution supporting multiple protocols:
- USB-PD (5V – 20V) + direct charging VDMs
- BC1.2 + QuickCharge 2.0, 3.0 & 4.0
- optionally proprietary protocols like Samsung AFC, Huawei SCP/FCP etc.
• TEA1936x/38 primary side controller
• TEA1993/98/99 SyncRec controller
- maximum Vout TEA1993, 98 and 99 is 20V, 6V and 15V
- TEA1998 and 99 offer 0.7% higher efficiency at 5V for direct charging applications
• TEA1905x multi-protocol controller
- optionally with I2C authentication IC
• TEA1903x is USB-PD only derivative
• TEA1901x is SCP (+ FCP/QC) derivative
- optionally other direct charging protocols
Application
• Type-C PD & QC Wall charging
Key Components

• TEA1901 SCP secondary side
Product Benefits
• higher efficiency (>91% for 12V/2.3A) and smaller form factor
• multi-protocol support and flexibility by programmability of key system parameters
• low external component count and low BOM cost due to high integration & support of NMOS port switch
• higher system safety due to wide set of hardware integrated protections
• low EMI due to high-side operation capability of TEA199x SyncRec IC
• flexibility as functionality & protections configurable so less Stock Keeping Units
