Power management integrated circuits, known as PMICs, are integrated circuits (ICs) that serve as an interface between the power source and the load. They are used in a wide range of electronics, from consumer electronics to industrial and automotive electronics. Power management ICs (PMICs) can be used to monitor and regulate the power output of a power source, reduce power consumption and increase system efficiency.

PMICs can be further categorized into several types, such as drivers and supervisors, low dropout (LDO) regulators, switching regulators and controllers. Supervisors are special type of PMICs that are used to monitor the output of power supplies and to reset the system in case of overvoltage and undervoltage, or to protect the system from the failure of the power supply, preventing the system from running out of power. LM3702YATPX-290/NOPB belongs to the Supervisors category.

The LM3702YATPX-290/NOPB Supervisors are specifically designed for monitoring the output voltages of dc-dc converters in applications such as industrial process control, robotics, and other systems exposed to harsh environmental conditions. These devices feature a wide operational range, a low quiescent current, and low frequency (30 kHz) operation. They are highly accurate, offering a reset threshold accuracy of ±2% over a wide temperature range.

The LM3702YATPX-290/NOPB monitors the output of the power supply, and when it falls below a certain pre-set threshold, it triggers an interrupt signal generated by an internal comparator. This interrupt signal is sent to the system, resetting the system and preventing it from running out of power. The threshold for the power supply can be set by the user, depending on their system requirements. In addition, the device also features open drain and push-pull output options, allowing flexibility in selecting the voltage level for reset.

The LM3702YATPX-290/NOPB includes a number of protective features that protect the system from overvoltage and undervoltage conditions. It is also equipped with a low voltage lockout (LVLO) circuit that locks out the device in case of undesirable levels. The device is also protected against false triggering of reset by a delayed start-up circuit that enables the supervisor to monitor the output power supply for a certain period before it is enabled. Finally, the device is also designed to accept wide input voltages from 2V-16V, allowing operation in a wide range of systems.

In summary, the LM3702YATPX-290/NOPB Supervisors are specifically designed for monitoring the output voltages of dc-dc converters, with a wide operational range, low quiescent current, low frequency (30 kHz) operation, reset threshold accuracy of ±2% over a wide temperature range, open drain and push-pull output options, and wide input voltages from 2V-16V. It is a reliable and cost-effective supervisory solution for a variety of industrial, robotic, and other systems exposed to harsh environmental conditions.
