DS2482S-100+T&R

DS2482S-100+T&R is a single-channel 1-wire host. It is an I²C-to-1-Wire® bridge device that interfaces directly to standard (100KHz max) or fast (400KHz max) I²C hosts to perform bidirectional protocol conversion between the I²C host and any downstream 1-wire server devices. Internal, factory-trimmed timers relieve the system host processor from generating time-critical 1-wire waveforms, supporting both standard and overdrive 1-wire communication speeds. To optimize 1-wire waveform generation, the DS2482-100 performs slew-rate control on rising and falling 1-wire edges and provides additional programmable features to match drive characteristics to the 1-wire server environment. Programmable, strong pullup features support 1-wire power delivery to 1-wire devices such as EEPROMs and sensors. Typical applications include printers, industrial sensors, medical instruments, cell phones, and PDAs.
