Introduction:

NTSB40100CTG is an integrated circuit which belongs to the tunnel rectifier family and is specially designed for automotive applications. It is composed of two independent rectifier arrays, each with two diodes and a control transistor, and includes integrated protection functions to prevent over-temperature, over-voltage and over-current. This article will discuss the field of application of NTSB40100CTG and details of its working principle.

Application Field

NTSB40100CTG is anticipated to be used in the fueling systems of automobiles, such as automotive fuel pumps, tanks and other parts. Its integration of a two-diode rectifier array with a control transistor makes it suitable for rectifying the voltage and providing a controlled current supply to the application. It is also suitable for supplying lights, horns, and other control elements, which require a high current. The NTSB40100CTG can also be used in chargers for laptops, mobile phones and other portable electronic devices. The diode and transistor arrays are used to control switching between input and output voltage, and to provide a regulated output with minimal losses. The integrated protection functions enable it to switch off the current supply in case of over-current, over-voltage or over-temperature.

Working Principle

NTSB40100CTG has two independent diode rectifier arrays with a control transistor. Its On-state voltage is determined by the voltage between the control and source terminals, while its leakage current is set by the voltage of the source terminal and is a function of the source-to-drain resistance. When the input voltage is greater than the On-state voltage, the transistor will be turned off, preventing current flow through the diodes. The device provides protection functions to prevent over-voltage, over-temperature, and over-current. In the case of over-voltage, when the voltage on the control terminal exceeds the On-state voltage, the transistor will be switched off and the current supply will be interrupted. The same applies for over-temperature, with the switch-off threshold dependent on the temperature sensing resistor. Finally, in the case of over-current, an integrated current-limiting circuit will be activated, preventing further current flow.

Conclusion

In conclusion, the NTSB40100CTG is an integrated circuit belonging to the tunnel rectifier family, specially designed for automotive applications. It is composed of two independent rectifier arrays, each with two diodes and a control transistor, and includes integrated protection functions for over-temperature, over-voltage and over-current.
