The SM72442MT/NOPB, a member of Special Purpose voltage regulator family, is a voltage supervisory device manufactured by Texas Instruments. It is mainly used to monitor the voltages in battery operated systems, where it serves an important role in protecting batteries from overvoltage. It is also used as a back-up supply supervisors, or a DC power supply monitoring circuits to provide better protection against uncontrolled voltage transients.

The Supervisory Voltage Regulator (SVR) is capable of monitoring batteries and providing protection against overvoltage and overcharging. It features a delay circuit and an internal switch, which help the device to respond quickly and accurately to abnormal voltages. The SVR also features a reset output, which can set a reset condition when the voltage drops below the lower threshold, and a power-on reset (POR) input to enable the SVR to maintain a lower line threshold in automatic standby condition. The SM72442MT/NOPB also features a voltage regulation indicator (VRI) pin, which can be used to detect if the voltage drops below the lower threshold. It also features an adjustable delay reset time (tDelay), to control how long the reset output stays active after the voltage drops below the lower threshold.

The SM72442MT/NOPB is suitable for multiple applications in battery-powered systems, such as consumer and automotive applications. It can be used to monitor the voltage of the battery cells, as well as in AC adapters and other voltage regulator circuits. It is also suitable for use as a supervisory circuit in DC power supply protection systems and in applications requiring a low reset threshold such as microcontrollers, embedded systems, and automotive ECUs.

The SM72442MT/NOPB can be used as the primary supervisor of a controller, or it can be used to prevent overvoltage conditions from occurring. When used to monitor the voltage of the battery cells, it helps to keep the cells in a safe operating range by controlling their charging and discharging rates. It can also be used as a supervisory circuit in AC adapters, and other voltage regulator circuits, to provide additional protection against voltage transients. In addition, it can be used as a reset output in microcontroller, embedded systems, and automotive ECUs.

The SM72442MT/NOPB is designed to work in a wide range of operating temperatures, from -40 to +125°C. The device is available in an 8-pin SOIC package, and is fully RoHS-compliant. It is capable of working with battery packs ranging in voltage from 1.5V to 12V, and is set up for operation without any external components, making it an easy-to-implement solution for many applications.

The SM72442MT/NOPB is designed to provide protection against overvoltage and overcharging of batteries, and to protect the installed system from damage caused by voltage transients. Its adjustable reset timedelay (tDelay) and voltage monitor output (VRI) pins enable efficient performance, and make it a robust and cost-effective solution for battery operated systems and other applications requiring a low reset threshold.
