QS8J11TCR Array Application and Working Principle

The QS8J11TCR array is designed to help enhance the capabilities of your transistors and MOSFETs. This integrated circuit\'s design allows for a single logic output pin to control multiple devices with a single logic level signal. It contains four logic sections providing up to sixteen independent control outputs. These outputs are open drain high side control stages which are designed for use with FETs and MOSFETs.

The QS8J11TCR array takes a single logic signal at its input, which is then converted into sixteen independent signals at its 16 outputs. The output signals are used to control the gates of FETs or MOSFETs, allowing individual devices (or groups of devices) to be switched on or off. The output signals are open-drain, so they may be used in voltages higher than VCC (the voltage of the power supply).

The QS8J11TCR array offers many advantages compared to traditional methods of controlling FETs and MOSFETs. First, since only one logic signal is needed for each sixteen output devices, this eliminates the need for multiple separate control wires. Second, the logic signal can be changed very quickly, as the array handles all the logic operations internally. Finally, the open-drain output allows the output devices to be controlled in voltages up to VCC + 50 volts.

One of the main applications of the QS8J11TCR array is motor control. When used with FETs or MOSFETs, the array allows a single logic signal to control the gates of up to sixteen motors simultaneously. Each output of the array functions as a high-side control stage, so when its associated output is high, it switches on the associated power FET or power MOSFET and its associated motor turns on.

The QS8J11TCR array also has applications in power windows and door locks. By using the array, a single logic signal can be used to controlup to sixteen separate power windows and door locks. Again, since the output signals are open-drain, the array can be operated in voltages higher than the power supply voltage.

The QS8J11TCR array is an ideal solution for any system requiring multiple outputs to be controlled by a single logic signal. Its combination of features makes it extremely versatile, and it offers a cost-effective alternative to traditional methods of controlling FETs and MOSFETs.
