Interface – Drivers, Receivers, Transceivers consist of devices use to drive, sense, and send data between two or more circuits. TLE7268SKXUMA1 is a device example from this category of interface. The technological application of this device and its working principles are discussed below.

Application Fields of TLE7268SKXUMA1

TLE7268SKXUMA1 is a device designed for automotive use and is typically used in advanced driver assistance systems (ADAS) such as night vision and lane departure warning systems. This device is also used to enhance system performance and safety, such as boosting the transfer of data in CAN, LIN and Flexray applications. TLE7268SKXUMA1 has an extended input voltage of up to 42V, allowing reliable operation even in extreme automotive conditions. It is also capable of performing well in shock and vibration, temperature and radiofrequency interference. TLE7268SKXUMA1 is also used in applications where signals from multiple subsystems are required such as in battery charging, cooling and climate control.

Working Principle of TLE7268SKXUMA1

The core component used in TLE7268SKXUMA1 is the integrated circuit of TLE7268SKXUM1 which is a dual-channel, high voltage, low-side driver. This IC operates with a low on-resistance of 300mΩ and is capable of driving up to 5A in each of its channels. This IC includes two overload/short-circuit sense paths and two thermal shutdown paths. The TLE7268SKXUMA1 also contains an integrated fast sampling comparator, an adjustable gate drive, an internal bootstrap circuit and pulsewidth modulation (PWM) outputs.

The working principle of TLE7268SKXUMA1 is quite simple. When a voltage is applied at the input of the device, it triggers the internal circuit to drive the output. The device has two independent outputs, one for each of the driving channels. Each output is driven by two gate drivers, one controlling the on-time of the output and the other controlling the off-time. The data driven by the device is based on the input voltage and the PWM settings of the device which can be adjusted as needed. The maximum on-time and off-time of the PWM set by the device can also be adjusted in order to fine-tune the final output.

The TLE7268SKXUMA1 also features a wide range of protection features. The precharge path prevents undesired inrush currents and lowers the startup current of the output. The integrated overload/short-circuit sense path monitors the load current of the output and from this it can shut down the outputs in case of a fault. The integrated thermosensors ensure that the device thermal limit is not exceeded during operation, thus protecting the device from overheating.

The TLE7268SKXUMA1 is an excellent device for use in automotive applications, primarily due to its wide input voltage range and robust protection features. Its two-channel design makes it the perfect solution for applications requiring signal transmission between multiple subsystems. Its simple working principle and adjustable parameters make it easy to use, making it an ideal choice for any automotive application.
