SLG55544 - USB Charging Port Power Switch and Controller

General Description

Renesas SLG55544 is a combination of current-limited USB port power switch with a USB 2.0 high-speed data line (D+/D-) switch and USB charging port identification circuit.

Applications include notebook PCs and other intelligent USB host devices.

Key Features

  • low capacitance and low on resistance, allowing signals to pass with minimum edge and phase distortion. The SLG55544 monitors D+ and D-, providing the correct hand-shaking protocol with compliant client devices. Features.
  • Meets Battery Charging Specification BC1.2 for DCP and CDP.
  • Meets Chinese Telecommunications Industry Standard YD/T 1591-2009.
  • Supports Non-BC 1.2 charging modes via Automatic selection - DM/DP Divider Modes 2.7V/2.0V (1A) & 2.0V/2.7V (2A) - DM/DP 1.2.
