Product Summary

The DS2406P+ is a Dual Addressable Switch Plus Memory. It offers a simple way to remotely control a pair of open drain transistors and to monitor the logic level at each transistor’s output via the 1-Wire bus for closed loop control. Each DS2406P+ has its own 64-bit ROM registration number that is factory lasered into the chip to provide a guaranteed unique identity for absolute traceability. The DS2406P+’s 1024 bits of EPROM can be used as electronic label to store information such as switch function, physical location, and installation date. Communication with the DS2406 follows the standard Dallas Semiconductor 1-Wire protocol and can be accomplished with minimal hardware such as a single port pin of a microcontroller.

Parametrics

DS2406P+ absolute maximum ratings: (1)Voltage on DATA or PIO-A to Ground: -0.5V to +13.0V; (2)Voltage on VCC or PIO-B to Ground: -0.5V to +6.5V; (3)Operating Temperature Range: -40°C to +85°C; (4)Storage Temperature Range: -55°C to +125°C.

Features

DS2406P+ features: (1)Open drain PIO pins are controlled and their logic level can be determined over 1-Wire bus for closed-loop control ; (2)Replaces and is fully compatible with DS2407 but no user-programmable power-on settings and no Hidden Mode ; (3)PIO channel A sink capability of 50mA at 0.4V with soft turn-on; channel B 8mA at 0.4V; (4)Maximum operating voltage of 13V at PIO-A, 6.5V at PIO-B; (5)1024 bits user-programmable OTP EPROM; (6)User-programmable status memory to control the device; (7)Multiple DS2406’s can be identified on a common 1-Wire bus and be turned on or off independently of other devices on the bus; (8)Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures error-free selection and absolute identity because no two parts are alike ; (9)On-chip CRC16 generator allows detection of data transfer errors.
