LMX393HAUA+

The LMX393HAUA+ is a 3-pin linear-comparator programmable single and dual voltage detectors designed for applications requiring a low operating current and a low standby current. It offers a wide selection of precision, adjustable trip points with a wide choice of detection levels. The device also features power-on reset, programmable threshold and hysteresis, adjustable voltage reference. It is designed for use in portable and low noise applications where accuracy is important.

The LMX393HAUA+ is used in a variety of applications, such as voltage measurement and control, overvoltage and under-voltage detection and protection, temperature control and overcurrent protection. It is also used in power supplies, communications systems, security systems, and various other electronic systems.

The LMX393HAUA+ uses a programmable comparison principle to detect when a pre-set threshold is exceeded. It includes an electrically isolated power supply, a comparator circuit and output stage. The input signal is compared to a voltage reference. When the input signal exceeds the threshold, the comparator outputs a logic level high. When the input signal is lower than the threshold, the comparator outputs a logic level low. The output stage can be configured for a number of output options including pulse-width-modulated (PWM) output.

The LMX393HAUA+ offers a wide selection of adjustable trip points, enabling precise monitoring of voltage levels. It also features an internal adjustable voltage reference for precise accuracy and is available in three different package sizes, depending on the required application. Its integrated self-reset circuitry allows it to reset itself when the power supply is shut down or restarted, ensuring that it always starts up correctly.

The LMX393HAUA+ is a versatile and reliable system for applications requiring voltage monitoring and control. Its programmable trip points, low operating current, adjustable voltage reference and power-on reset enable it to provide reliable operation where accuracy and precision is required.
