USB charger detection interface

下载数据手册

The STUSBCD01B is a USB charger detection IC which can detect dedicated USB chargers, Host/Hub chargers or standard host ports connected to the USB DP/DM data lines.

The device implements two different detection methods in order to be able to distinguish between a dedicated charger and a Host/Hub charger.

Operation is controlled through three general purpose I/O pins; a hardware open drain detection output is also available.

An internal regulator provides the 1.8 V supply voltage for the internal blocks and state machine while a clamping device prevents VBUS voltage from going over 6 V (typ.).

The STUSBCD01B is available in a 12 bumps Flip-Chip 0.4 mm pitch package.

Key Features

  • Low DP-DM input capacitance
  • VBUS voltage 6 V clamping circuit
  • 12 bumps Flip-Chip package, 1.6 x1.2 mm, pitch 0.4 mm, max thickness 0.60 mm, Halogen free RoHS compliant package
  • Capable of detecting dedicated USB chargers and host chargers (current sink and dedicated methods)
  • Active high open drain hardware detection pin (DETECT)
  • Operates with VBAT supply voltage ranging from 2.2 V to 4.5 V
  • 1.6 V - 2.8 V interface voltage range (VIO )
  • ESD: HBM ± 2 kV, CDM 500 V on every pin
  • GPIO control interface
