Maxim Integrated Products introduced the MAX13481E, MAX13482E and MAX13483E 15kV ESD-protected, USB full-speed transceivers in a 3-by-3mm, 16-pin TQFN package. These new devices feature a logic-selectable suspend mode that reduces current consumption and provides a USB-compliant interface to low-voltage ASIC/CPUs, making them suitable for handheld devices such as cellphones and PDAs. The USB D+ and D- data lines are protected to 15kV per the Human Body Model. Additionally, these transceivers are compliant with the USB full-speed (12Mbps) requirements.

The MAX13481E has an active-low enumeration input that controls an internal pull-up switch, and is pin-for-pin compatible with Micrel's MIC2551A and PointChips' DP1681. The MAX13482E has an active-low enumeration input that controls an internal 1.5 kilohm and D+ pull-up resistor. The MAX13482E and MAX13483E offer Vbus detection, and are pin-for-pin compatible with the PointChips DP1682 and DP1680, respectively.

The MAX13481E, MAX13482E and MAX13483E operate over the extended -40C to 85C temperature range. Prices start at 73 cents for 1,000 units and up.
