Power management integrated circuits (PMICs) are a part of the integrated circuit (IC) family and are used to manage the power consumption of electrical devices. PMICs are used in almost all electronic devices, from small consumer products to large industrial machines. PMICs help to provide the power supply and efficiently manage the power resources to critical components of the device.

Supervisors are PMICs that are specifically designed for monitoring and managing the voltage levels of different ICs in the same system. These ICs typically contain a variety of software, firmware and hardware components to effectively do the job. MAX815TESA+ is one such IC which is designed as a low-cost voltage supervisor offering high accuracy, low power consumption and high temperature range.

Application Field & Working Principle of MAX815TESA+

The MAX815TESA+ is a low-cost single-channel voltage supervisor specifically designed for monitoring and controlling the voltage levels of various components within the same system. It is equipped with a precision voltage monitor and a reference module. The voltage monitor is a fully monolithic linear system that is capable of detecting soon expected power failures, setting of warning thresholds, and correlating with the temperature of the device. The reference module, on the other hand, provides precise and accurate voltage measurements, which are used to judge the acceptable voltage levels for the components in the system.

The basic working principle of the MAX815TESA+ is to constantly monitor the voltage levels of different components and compare it against the preset minimum and maximum threshold values. Generally, the max connected device should not be higher than 2.6V and the min should not be below 1.2V. In case the voltage level is found within the acceptable range, the MAX815TESA+ will send out a Reset signal. If however, the voltage found is outside the acceptable range, an alert will be sent and the internal circuit of the device will be shut down.

The MAX815TESA+ is used in a wide range of applications ranging from personal computers, embedded systems, audio amplifiers, computers, industrial automation, datacom systems, telecommunication systems, handheld devices, and consumer electronics. It is widely used to protect against unexpected volatility in power supply and reduce the risk of operational malfunctions due to sudden power failure. It is also used to establish a secure and reliable operating environment for integrated circuit (IC) systems and microcontroller-based applications.

The MAX815TESA+ IC is easy to use, reliable and highly accurate. Its accurate voltage monitoring and precise comparison provide an efficient system for voltage regulation, thereby leading to improved system reliability. In addition, it consumes very low power and runs across an extended temperature range, thus proving itself to be the perfect solution for applications with stringent power and temperature requirements.
