HIN207CAZ

HIN207CAZ is an interface driver/receiver/transceiver that meshes a variety of signal standards – most notably, RS-232, RS-422, and RS-485 – and supports ESD, EMC, and short circuit protection. With its vast signal connectivity, HIN207CAZ can be used in an even wider range of applications, from automotive and industrial to computing and communications, with reliable signal transmission and isolation.

The HIN207CAZ is specifically designed for two-wire inter-connectivity. Its non-inverting ASIC architecture ensures high ESD and electrical transient/noise immunity. With its proprietary avalanche ruggedized design, HIN207CAZ is able to withstand up to 3600V of ESD and 2.4kV of electrical transients. The device is also capable of 6Mbps low-power line-speed operation and can easily detect common mode faults, such as those caused by cable breaks.

The main features of the HIN207CAZ include:

• Tri-directional design provides ESD, short circuit, and EMC protection
• Avalanche ruggedized ESD design withstands up to 3600V ESD and 2400V electrical transients
• Low power line-speed operation up to 6Mbps
• Adaptive terminating circuitry compensates for line transients
• Conformal coating for enhanced moisture protection
• Compatible with a variety of signal standards such as RS-232, RS-422, and RS-485

The working principle of the HIN207CAZ is built around a differential driver and receiver design. The differential driver is a low-power device that sends out a differential voltage (Vdiff) to the output. This differential voltage is received by the receiver, which amplifies it and sends it to the input. Since the receiver is a high-impedance element, it does not induce any load on the solenoid or motor connected to it. This is especially important for motor control applications, where the presence of a load would cause the motor to stop running.

The driver is also capable of detecting common mode faults, such as line breaks and open loops. These faults are detected by comparing the voltage at the driver output to the voltage of the receiver input. If the two voltages do not match, then there is a fault detected. The driver then isolates the faulty line, protecting the line from further damage.

The HIN207CAZ is an extremely versatile interface driver/receiver/transceiver that can handle a variety of different applications. It is ideal for harsh industrial environments, with its ESD and EMC protection, low-power line-speed operation, and adaptive terminating circuitry. Its low-power design also makes it perfectly suited for automotive, computing, and communications markets.
