USB signal conditioner is self-adapting
Operating from a supply voltage down to 2.3 V, the PI5USB212 signal conditioner IC from Diodes automatically detects a USB 2.0 high-speed connection. The part, which is intended for use in PCs, docking stations, cable extenders, and monitors, preserves signal integrity when driving long PCB traces or cables extending up to 5 meters.
The PI5USB212 symmetrically boosts the USB D+ and D- channels to maintain common-mode stability. It also applies pre-emphasis to compensate for intersymbol interference (ISI). The IC’s wide supply range of 2.3 V to 5.5 V simplifies system design and extends the operating window of portable and battery-powered equipment.
To converse energy, the PI5USB212 automatically detects when a USB device is not attached and reduces its supply current to just 0.7 mA typical. When the IC is disabled via the RSTN disable pin, it minimizes current consumption to just 13 µA typical. In addition to USB 2.0, the PI5USB212 is compatible with USB On-The-Go (OTG 2.0) and Battery Charging (BC 1.2) specifications.
Housed in a 12-pin, 1.6×1.6-mm QFN package, the PI5USB212 signal conditioner costs $2.70 each in lots of 3500 units.
