MP5034 3.6-14V USB Charging Port Controller Integrating QC 3.0 Protocol TSOT23

MP5034 3.6-14V USB Charging Port Controller Integrating QC 3.0 Protocol TSOT23

The MP5034 supports DCP schemes for battery charging specification (BC1.2), divider mode, 1.2V/1.2V mode, and quick-charge specification (QC 3.0) without the need for outside user interaction.

Key Specifications

Features

• Wide 3.6V to 14V Operating Input Voltage Range
• Supports QC 3.0 (3.6V - 12Vbus with 1% Accuracy) and DCP Schemes for BC1.2, Divider Mode, and 1.2V/1.2V Mode
• Input Discharge during High Voltage to Low Voltage Change
• Compatible with Buck, Boost, and AC/DC Converters
• Available in a TSOT23-8 Package

Typical Application Circuit

Applications

• USB Charger Controller
• AC/DC Wall Adapter with USB Ports

Design Notes

• Check the input common-mode range against the actual signal, especially in single-supply rails where ground-referenced signals sit at the edge.
• Capacitive load drives stability; add series isolation when driving cables or ADC inputs directly.
• Offset voltage and its drift, not gain bandwidth, usually set the achievable accuracy in DC instrumentation.
• Decouple at the pin with the smallest package capacitor that meets the transient requirement, returned to a local ground.
