The SN75453BDG4 is a part of the Texas Instruments family and is categorized as a PMIC–Gate Drivers. This part is used as a circuit protector, specifically called a voltage shifter. The device is designed to help prevent overheating and limit power surges. It is able to control the current flow to and from a circuit, allowing it to be used as a method of protection in various electrical applications.This voltage shifter is a high-voltage, low current type device that is used to protect circuits from overvoltage and undervoltage conditions. It functions by dividing the input voltage and passing just enough current through the device to power the circuit, but not enough to cause any damage due to an overvoltage or undervoltage situation. This device is commonly used in automotive, industrial, and consumer electronic applications.The SN75453BDG4 also offers overvoltage protection and overcurrent protection. Overvoltage protection is provided by the shift register, which is essentially a series of diodes. When the input voltage exceeds the threshold, the diodes are triggered, which redirects the excess current away from the circuit, protecting it from any damage it might otherwise cause. Overcurrent protection is provided by the series of FETs, which temporarily shut off power when the current exceeds a certain set point.Another feature of the SN75453BDG4 is its wide range of input voltage, which is typically between 6V and 25V.The output voltage is also wide, which is usually between 4V to 15V. It has a peak output current of 200 mA, and can handle a steady load of up to 20 mA.The SN75453BDG4 is designed to provide protection against static discharge, and is able to withstand any voltage surge up to 400V, which is significantly higher than many other voltage protectors, such as the SN74121, which can accept up to 100V.In summation, the SN75453BDG4 is a voltage shifter which offers a wide range of input and output voltages in order to protect circuits from overvoltage and undervoltage situations, as well as static discharge and potential damage from power surges. This PMIC–Gate Drivers part can be used in a variety of applications, including automotive, industrial, and consumer electronic applications.
