The MAX986ESA+T is a monolithic comparator circuit featuring low-power operation, rail-to-rail input, and an adjustable push-pull or open-drain output stage. The device is well suited for applications including electric motor control, liquid-level control, power supply monitors, and thermal protections. It is pin compatible with the MAX986 and similar components and is linear in operation.

Design

The chip features a linear input stage, a high performance operational amplifier and a precision voltage reference circuitry. The linear input stage allows for a wide input voltage range, up to 18V. The device’s output stage features an adjustable push-pull or open-drain output, which allows for output control. The device is protected by short-circuit protection, current and ESD protection, and overload and current limit protection.

Features

The MAX986ESA+T comes in a small 8-pin TSSOP package which makes it suitable for a variety of applications. It has a wide operating Voltage range, up to 18V and a wide input common-mode range. The output drive capability is adjustable, allowing for both push-pull or open-drain outputs, and it is protected against short circuiting. It is also protected against ESD, overvoltage and thermal protection. The device also features low power dissipation and low input bias, accuracy, and output-offset current.

Applications

The MAX986ESA+T can be used in a wide range of applications, including electric motor control, liquid-level control, power supply monitors, and thermal protections. It can be used for voltage comparators, current-sensing circuits, and over-temperature, over-current protection circuits. It can also be used for unipolar and bipolar output switching circuits, as well as for analog-to-digital converters, comparators, and current/voltage comparators.

Working Principle

The MAX986ESA+T comparator operates by comparing the voltage at the positive input terminal with the voltage at the negative input terminal. If the positive input voltage is higher than the negative input voltage, the output will be low. If the negative input voltage is lower than the positive input voltage, the output will be high. The device also features a reference voltage input, which can be adjusted to set the comparator’s trip point.

Conclusion

The MAX986ESA+T is a monolithic comparator circuit which is well suited for applications that require low-power operation, rail-to-rail input, and adjustable push-pull or open-drain outputs. Its wide operating voltage range and input common-mode range makes it suitable for a wide range of applications, such as electric motor control, liquid-level control, power supply monitors and thermal protection. Its push-pull or open-drain output stages, current limit and overvoltage protection, and short-circuit protection make it a reliable choice for these applications.
