Dallas Semiconductor's DS2413 chip is a dual-channel, programmable GPIO that protects against possible power fault conditions in end applications. All device pins can withstand sustained levels up to 28 V. Two DS2413 ports can independently operate as input or output at levels as high as 28 V d.c.
In addition, the open-drain outputs can each sink 20 mA, making them ideal for LED control. The DS2413 includes a unique 64-bit ID number which, combined with the I/O features, provides a solution for accessory and peripheral control and identification. The 64-bit value can also be customised to encode model information for the accessory or end product.
Device operation, including communication, control, and power, is performed over the two-contact 1-wire interface, enabling line lengths between a host system and slave devices that can extend tens of meters with hundreds of multidropped 1-wire devices.
The DS2413 GPIO operates from 2,8 V to 5,25 V over a 0 to +70°C and is available in 6-pin TSOC packaging.
