The TSM931ESA+T, also known as the low-power precision single comparator, is an integrated chip that belongs to the Linear - Comparators family of devices. The TSM931ESA+T has been designed and manufactured to provide a low-power, precision single-comparator solution for a variety of analogue and digital applications.

The TSM931ESA+T includes a comparator with a pre-set voltage which is used to compare the input voltage with the pre-set voltage. Once the pre-set voltage is reached, the comparator will trigger an output to indicate the condition. The TSM931ESA+T allows for low-power operation with a low quiescent current of 7µA and a low-current mode of 0.1µA. This makes the comparator ideal for battery-powered applications. The open-drain output is available in either logic or open-drain source formats.

The TSM931ESA+T is suitable for a range of applications, including level indicator, current limit setter, over-temperature protection, over-voltage protection and peak detector. It is also suitable for use in low-power analogue-to-digital and digital-to-analogue conversions circuits, including buck converters and voltage references. In addition, the TSM931ESA+T can be used in circuits for over-current and over-current protection, and for generating a digital control signal.

The working principle of the TSM931ESA+T can be summarised as follows: the IC consists of an operational amplifier, a reference voltage generator, an input voltage source, and an output. The operational amplifier acts as a high-gain voltage follower and amplifies the input voltage and the reference voltage, which are then compared. If the input voltage is greater than the reference voltage, the output signal is LOW, otherwise it is HIGH. The output is usually connected to a signal indicator, such as an LED or a relay. This allows the device to be used as a signal indicator.

The TSM931ESA+T is a versatile, low-power solution for a wide range of applications and is suitable for a variety of analogue and digital circuits. It delivers precision, low-power operation and is cost effective. It is also available in a wide range of packages, allowing for a tailored solution to meet the specific needs of the application.
