High-/Full-Speed USB 2.0 Switches with High ESD

Active: In Production.

The MAX4906EF are electrostatic discharge (ESD)-protected analog switches that combine low on-capacitance (C_ON) and low on-resistance (R_ON) necessary for high-performance switching applications. The COM_ inputs are protected against ±15kV ESD without latchup or damage. The device is designed for USB 2.0 high-speed applications at 480Mbps. The switches also handle all the requirements for USB low- and full-speed signaling.

The MAX4906EF features two single-pole/double-throw (SPDT) switches. The device is fully specified to operate from a single +2.7V to +3.6V power supply and is protected against a +5.5V short to all analog inputs (COM_, NC_, NO_). This feature makes the MAX4906EF fully compliant with the USB 2.0 specification of +5.5V fault protection. The device features a low threshold voltage and a +1.4V V_IH, permitting them to be used with low-voltage logic. The device features a active-low QP input that when driven high, turns the charge pump off and sets the device in standby mode. When the device is in standby mode, the quiescent supply current is reduced to 3µA (max) and the switches remain operable.

The MAX4906EF is available in a space-saving, 2mm x 2mm µDFN package and operates over a -40°C to +85°C temperature range.
