±15kV ESD-Protected USB Level Translator in UCSP with USB Detect
General Description
The MAX3341E USB level translator converts logic-level signals to USB signals, and USB signals to logic-level signals. An internal 1.5kΩ USB termination resistor supports full-speed (12Mbps) USB operation. The MAX3341E provides built-in ±15kV ESD-protection circuitry on the USB I/O pins, D+ and D-, and VCC. The MAX3341E operates with logic supply voltages as low as 1.8V, ensuring compatibility with low-voltage ASICs. The suspend mode lowers supply current to less than 50µA. A unique enumerate feature allows changes in USB communication protocol while power is applied. The MAX3341E is fully compliant with USB specification 1.
