TND315S-TL-E Application Field and Working Principle

TND315S-TL-E is a three-state power distribution switch, load driver device, which is classified as part of Power Management Integrated Circuits (PMIC) group and it is manufactured by NXP Semiconductors. This device is primarily used in automotive and industrial applications, such as computers, consumer electronics, home appliances, power supplies, etc. It functions with a wide input/output voltage range from -2.3 to 25V and has a peak load current of up to 2 A.

TND315S-TL-E is designed to provide a very high degree of versatility and power efficiency through its features and performance, along with the industry leading ESD protection. Its 3-state configuration allows to switch two loads independently and it can also drive both resistive as well as capacitive loads. The device is also ideal for current limiting applications including motor control, PWM speed control, and other load switching applications such as transistors.

Working Principle

The TND315S-TL-E device is based on a simple electrical operating principle of conduction, whereby current flow is induced between two points which are electrically connected. This is achieved by linking two power switches, where the first switch is connected to the input voltage source while the second switch is connected to the load, as represented in the schematic. When the input voltage passes through the switch, a current flow is induced in the load, due to the electrical connection. In addition, when the switch is connected to the load, it provides additional protection by restricting the current flow before it reaches the load.

As mentioned above, the TND315S-TL-E device has two independent switches for switching two different loads. Each switch is then connected to its own logic input, G1 and G2, which allows for either an OFF or ON state to be applied. The logic input also allows the device to be configured to have either a continuous or time-controlled power distribution, depending on the application requirements. Additionally, the TND315S-TL-E device also has an additional output pin, P. When this pin is set to high, current will pass through the switch and the load will be activated, whereas when current is set to low, current will not pass through the switch and the load will be deactivated.

Apart from the switches and the logic inputs, the TND315S-TL-E device also has an optional Enable pin, which is an input pin that is used to enable the device when set to high, or disable it when set to low. The Enable pin also has an optional internal pull-up resistor, which is used to keep the device enabled when in an open state. A Status flag output is also useful as it provides feedback on the device’s operating status, either ON or OFF.

Features

The primary features of the TND315S-TL-E device are: maximum peak load current of up to 2A, wide input/output range of -2.3V to 25V, 3-state configuration, support for both resistive as well as capacitive loads, wide input capability of 2.3V – 25V, support for time-controlled or continuous power distribution, robust ESD protection, and optional enable pin.

The TND315S-TL-E device is very efficient when compared to other load switches and it is ideal for applications such as motor control, PWM speed control, current limiting and other load switching applications. Its features and performance make it extremely well suited for use in automotive and industrial applications.
