TPCH442EG

This device is a bidirectional, low-power, dual-port, high-speed USB 2.0 analog switch with integrated protection for USB Type-C systems. It can be configured as a dual 2:1 or 1:2 switch, optimized for USB 2.0 DP/DM lines in USB Type-C systems. The device achieves true isolation — even when COM+/- exceeds VCC, only minimal current flows back to the supply. It features low bit-to-bit skew and high inter-channel noise isolation, and is compatible with multiple standards such as high-speed USB 2.0 (480 Mbps). Each switch is bidirectional with minimal or no attenuation of high-speed signals at the output. The bandwidth is wide enough to transmit high-speed USB 2.0 differential signals (480 Mb/s) with excellent signal integrity.

Applications

• Mobile phones, tablets, and laptops
• Any application using USB Type-C or Micro-B connectors

Key features

• Low on-resistance, R on = 4.5 Ω
• 1.8V logic-compatible control pin
• High off-state isolation: -100dB @ 100KHz
• COM+/- covers VCC, enabling true isolation even when power fails
• Low channel-to-channel crosstalk: -97dB @ 100KHz
• High bandwidth (-3dB @ 550MHz) for USB2.0 high-speed routing
• Low quiescent current (< 2 uA) with wide supply voltage range (1.5 V ~ 5.5 V)
