MAX981EPA

The MAX981EPA is an ultra-low power SOT23-5 linear comparator and a member of Maxim Integrated\'s low-voltage, low-power and wide-temperature range linear comparator family. Based on the ultra-low quiescent current of 1.8μA, theMAX981EPA is best suited for battery-operated handheld and low-voltage, low-power systems like that in automotive applications requiring wide temperature range operation. It features an adjustable hysteresis range allowing inputs to be compared with an adjustable “deadband” between the two inputs. It also provides good noise immunity, a wide operating voltage, and a low input offset voltage.

The MAX981EPA operates from a dual 2.5V to 5.5V supply with a quiescent current of 1.8μA (one-tenth the current of other comparators). The device has an adjustable hysteresis allowing inputs to be compared with an adjustable “deadband” between the two inputs and provides the user with an easy-to-use signal processor. With its tiny SOT23-5 package and low quiescent current, the MAX981EPA is ideal for battery-operated handheld and low-voltage, low-power systems. The wide operating voltage and low input offset voltage make the device suitable for many applications such as battery-backed memory protection and power management.

The working principle of the MAX981EPA is based on a traditional comparator transfer charateristic, which compares two levels of voltage at its inputs and outputs a high or low level at the outputs depending on which input has the higher level. If the voltage difference between the two inputs of the MAX981EPA falls within adjustable hysteresis area, the comparator will maintain its initial output. An adjustable deadband is included in the circuit to prevent noise from falsely triggering the comparator.

The MAX981EPA can be used for a wide range of industrial and consumer applications, such as battery-backed memory protection, supply up or down detection, motor controller and power management, motor speed control, wireless handsets and PDAs, push-button switch debouncing, and overcurrent protection. The adjustable hysteresis and low quiescent current make it ideal for these applications.

In conclusion, the MAX981EPA linear comparator is an ideal choice for low-power, high-performance, and wide temperature range applications. Its adjustable hysteresis and low quiescent current make it an excellent choice for battery-operated handheld and low-voltage, low-power systems. With its tiny SOT23-5 package and wide operating voltage, the MAX981EPA is a great choice for many applications.
