VND5E050JTR-E is a Power Distribution Switch, Load Driver integrated circuit (PMIC) which is a member of the VND5E product family from ST Microelectronics. It is used to provide a high load current during voltage applications from 5.5V to 18V. It features an integrated Power Supply Sensor Logic (PSSL) as well as an Integrated PX Blanking Logic (IPXL).

The VND5E050JTR-E has two different output modes, with two different current limits. The two current limits are 50mA and 250mA respectively, allowing the device to be switched off at higher load currents and provide protection against over-current, undervoltage and overvoltage. Additionally, the device has an adjustable dead time feature, allowing the user to adjust the frequency of the output current pulses.

The device supports multiple operating modes such as pulseless, continuous and PWL mode. The pulseless mode ensures that the device is able to manage short pulse load currents up to 50mA, and helps to increase the efficiency of the system, while the continuous mode helps to reduce the switching time and power losses. The PWL (power level) mode helps to control the level of output current.

The VND5E050JTR-E is ideal for controlling the power distribution in applications such as lighting, automotive and industrial equipment, providing a high load current while also utilizing the maximum available power. By using the integrated Power Supply Sensor Logic (PSSL), the device is able to detect any change in input voltage and adjust the output current accordingly. This helps to maintain the system stability and improve efficiency.

The working principle of the VND5E050JTR-E is based on a Controlled Node Switch (CNS) architecture. The CNS architecture allows the device to have an adjustable dead time between the ON and OFF times and thus provides a wide range of operational frequencies. The device is also highly suitable for pulse-width modulation (PWM) applications and features a low-jitter architecture.

The device utilizes an internal clock signal and the adjustable dead time feature to control the output signal. When the input signal is provided, the internal clock triggers the switching process, and the dead time allows the device to switch off the output signal before the new signal is applied. In this way, the system is able to provide a constant and accurate output signal while being highly efficient in terms of both power consumption and output current.

The VND5E050JTR-E is an ideal device for providing a high load current while utilizing the maximum available power. It can be used in a variety of applications such as lighting, automotive and industrial equipment because of its integrated Power Supply Sensor Logic (PSSL) and PX Blanking Logic (IPXL). The device also features a Controlled Node Switch (CNS) architecture, adjustable dead time feature, and is suitable for pulse-width modulation (PWM) applications.
