Introduction

DS481TM/NOPB is a serial bus transceiver manufactured by Texas Instruments, targeted at baud rate of up to 1 Mbps. It is specifically designed to fit into the standard SENT protocol and it supports the low-power operation of 1.5V to 5V operating voltage. It is compatible with various industrial interfaces such as RS232, RS485 and RS422, as well as several other legacy systems. The DS481TM/NOPB provides an immediate efficient solution for connecting to UART-compatible digital devices to communicate over asynchronous serial busses.

Application

The DS481TM/NOPB transceiver can be used in a wide range of applications. It can be used for data communications within industrial and automotive systems, medical equipment, and more. Moreover, it can be used in applications such as motion control, building automation, connectivity for I/O modules, and portable electronics. Since the DS481TM/NOPB transceiver supports fast data transmission and low-power operation, it can also be included in many embedded applications. For example, it can be used as a communication interface in robotics, implanted medical devices, and other sensing and control systems.

Features

Several features make the DS481TM/NOPB transceiver a great choice for these applications. First, it provides programmable baud rates and adjustable data formats to meet various needs. The transceiver is equipped with the ability to detect the presence of a network and initiate connection automatically. It also features a wake-up pin for sleep-mode wake-up. The DS481TM/NOPB also contains several protection features for reliable communication, such as protection against noise, electromagnetic interference, and power supply glitches. The enhanced edge rate control provide glitch-free transmission even in applications with high speed data rate.

Working Principle

The DS481TM/NOPB transceiver is designed to adhere to the SENT protocol. This means that it will synchronize the transmitter and receiver of two UART devices. The transceiver encodes the transmitted data from the transmitter and decodes it into the computer’s address bus. The transceiver also verifies the data and generates response bits. The DS481TM/NOPB also supports bi-directional communication, allowing the transceiver to transmit and receive data simultaneously. The transceiver sends and receives data based on RS-485 protocol, which signifies voltage level and line configuration. Moreover, the DS481TM/NOPB features TXD and RXD pins that set the data flow in either direction.

Conclusion

The DS481TM/NOPB transceiver is an efficient and reliable solution for connecting UART-compatible devices to asynchronous serial busses. Its fast data transmission and low-power operation makes it ideal for a wide range of applications, from embedded control systems to motion control and industrial automation. It also features several protection features for reliable communication, as well as programmable baud rates and adjustable data formats. The unique features of the DS481TM/NOPB transceiver make it an ideal choice for multiple applications.
