On July 8, 2013, Beijing News recently, Texas Instruments (TI) announced the launch of the latest series of fully integrated IO-LINK physical layer (PHY) devices, which not only can replace discrete implementations, but also provide a high degree of flexibility Sex. Compared with similar products, the SN65HVD101 and SN65HVD102 support higher output current and higher operating temperature, and can be used for point-to-point communication applications such as pressure, level, temperature or flow IO-LINK sensors, and IO in harsh industrial applications. -LINK actuator driver and valve.

The main features and advantages of SN65HVD101 and SN65HVD102
· High integration reduces board space: The latest IO-LINK PHY device integrated voltage regulator can provide up to 20mA of current for local circuits, which not only reduces the board area by 50% compared to discrete implementations, but also It can also realize the adaptation to the existing 3.3V or 5V controller;
· Respond to cross-line faults: These devices integrate steady-state protection up to 40V to avoid damage caused by installation faults or cable breaks. The transient protection up to 50V can avoid the damage to the field voltage caused by the sudden power increase, so no external protection device is needed;
· Maximum operating temperature: SN65HVD101 and SN65HVD102 support an operating temperature range of -40C to + 105C, and are the only IO-LINK PHY devices that support robust functions and are suitable for harsh industrial applications;
The widest output current: These integrated circuits can drive up to 480 mA for the interoperability of various sensors and small actuators, while competing products can only drive 300 mA or less. In addition, the output current can also be set with a single resistor to provide self-limiting functions for safe operation in low-power applications.
The solution using IO-LINK includes a microcontroller (MCU) in the standard configuration of the slave device. TI's ultra-low power MSP430TM MCU is the best choice for point-to-point communication and low-power operation. Using 512KB of flash memory and an integrated analog-to-digital converter (ADC), these MCUs can be used to quickly process data from various sensors.
