SN75185DWR Integrated Circuits (ICs)

The SN75185DWR is an interface device that belongs to the Drivers, Receivers, Transceivers category. It is designed for interfacing with a microcontroller, microprocessor or DSP, providing basic bidirectional communication protocols. The device is a low-power transceiver designed for use in a variety of controlled environments, such as battery-powered applications, medical applications, industrial automation and computer peripherals.

The main features of the SN75185DWR include a high-voltage differential input/output (HVIO) capability and a unique 0.45V supply threshold detection. It also includes a power-on-reset and dual enable input logic. The HVIO enables the device to be used as a differential driver or receiver in data transfers that require low power consumption. It is ideal for applications where low-power operation is essential, such as hand-held and portable devices. Additionally, the low power-on-reset (POR) functionality enables the device to be used in battery operated designs where the system must be reset when the battery runs low.

The SN75185DWR features an I/O configuration capability that allows for multi-mode capabilities, such as single-ended, push-pull, and three-state communications. It can also be used with the I2C, SPI, and other serial communication protocols. The device’s enhanced protection features protect the system from diodes, undervoltage, ESD, and other parameters.

In terms of working principle, the SN75185DWR features an external I/O-level selection for either voltage level (VL) or current level (CL) operation. In VL mode, the logic is controlled by external input/output voltages. In CL mode, the logic is controlled by external current levels that are determined by the input/output logic level. The device also includes a unique 0.45V supply threshold detection that allows the device to detect a low-battery idea. This feature will activate the power-on-reset function, allowing the device to shut off the power to the system when the battery runs low. It’s important to note that the SN75185DWR also includes a zero-crossing detector, which enables the device to accurately detect a low-power state or a high-power state.

The SN75185DWR is ideal for use in medical, industrial, and computer applications. It is used in medical devices, such as glucose meters and heart rate monitors, that require accurate, low-power data transfers. It is also used in industrial applications, such as industrial automation systems, where minimal power-consumption is essential. Additionally, the device is used in a variety of computer peripherals, such as modems, printers, and network cards. This is possible due to the device’s low-power operation and wide I/O configurability.

In conclusion, the SN75185DWR is a high-performance, low-power differential transceiver that is designed for applications where low-power operation is essential. It is an ideal solution for devices that require minimal power-consumption, such as medical and industrial devices, while also offering I/O configurability that allows multiple communication protocols to be used. Furthermore, the device includes a 0.45V supply threshold detection and power-on-reset function that can be used to detect a low-power state or a high-power state. Overall, the SN75185DWR is an excellent solution for applications requiring low-power communication protocols.
