Comparators are components used to measure and compare analog signals. They come in a variety of shapes and sizes, depending on their application. The TLV3702CDGK is a low-power CMOS, voltage-to-current comparator. It is a specific type of linear-input comparator.

TLV3702CDGK Application Field

The TLV3702CDGK is primarily used for non-inverting digital and analog control applications such as battery monitoring, touch-screen panel excitation, H-bridge motor control, tachometer signals and over-current detection. It can also be used as a switch, amplifier, indicator and switching circuit. The connection time of the comparator is controlled by an external capacitor, making it an ideal choice for applications with limited space.

Working Principle

The TLV3702CDGK comparator uses the linear-input principle, meaning the input signals are fed straight into the device and compared against a reference voltage to determine its output. When the input voltage is greater than the reference voltage, the output is switched to a logic high level. Conversely, when the input voltage is lower than the reference voltage, the output will be at a logic low level. The advantage of this type of comparator is that it has a low power consumption, making it an ideal choice for battery-oriented projects.

The comparator can be powered by a low-voltage supply or, alternatively, by an external jumper connected directly to the comparator, eliminating the need for a separate power supply. It can be used with a wide range of input logic signals and is designed to operate with a fairly large voltage range. The comparator has built-in hysteresis, which ensures a stable output even in noisy environments.

The comparator has two main sets of pins; the input pins, which accept the input voltage, and the output pins which supply the output level that is determined by the input voltage. The ground pin serves as a common reference point and is connected to the power supply ground.

Conclusion

The TLV3702CDGK is a low-power CMOS, voltage-to-current comparator that utilizes the linear-input principle. It is primarily used for non-inverting digital and analog control applications, such as battery monitoring, touch-screen panel excitation and H-bridge motor control. It can be powered by a low-voltage supply or, alternatively, by an external jumper, eliminating the need for a separate power supply. The comparator has built-in hysteresis, which ensures a stable output even in noisy environments.
