Power Management Integrated Circuit (PMIC) is an important component used in a wide range of applications and is an essential element in system design. Supervisors and references are important categories of PMIC, which are both vital for maintaining power integrity. MAX16116H2307MC+ is a voltage supervisor that has been emerging in recent years for its wide application and reliable performance. Its application field and working principle will be further discussed in this article.

Application Field of Max16116H2307MC+

Max16116H2307MC+ voltage supervisors are widely used as power-supply monitors in applications such as computing systems, communication systems, consumer electronics, and other industrial systems. Specifically, the Max16116H2307MC+ can be adopted in CPU voltage monitoring, system reset, low power monitoring in systems, power on reset, and soft start applications.

The Max16116H2307MC+ voltage supervisor supplies 1.8V to 5.5V voltage range, with a maximum current supply of 3mA, which makes this device suitable for power supply monitoring in a variety of systems. As the device also features a 12mΩ typical on-resistance, it is making a cost-effective solution in many fields. In addition, the built-in pull-up current source and thermal shutdown circuitry bring more protection and flexibility to the power supply systems.

Working Principle of Max16116H2307MC+

Max16116H2307MC+ voltage supervisors contain two comparators that monitor an external threshold voltage with reference to an internal voltage. When the voltage at the supervisor input goes lower than the programmable threshold voltage, the reset signal assertion is generated to the D output. The D output then drives the internal 2.2kΩ pull-up or pull-down resistor.

When the input voltage is higher than the threshold voltage, the power-on reset signal is deasserted, which then triggers a protective circuitry to reset the system. This resetting time is determined by an external capacitor that is connected to the supervisor. A properly selected capacitor will make sure the resetting time remains within the specification given by the device vendor.

In addition to being used as an undervoltage monitor, Max16116H2307MC+ can also be used in power cycle reset process. It can monitor the overvoltage so that a reset signal is triggered when an overvoltage is detected. This feature enables the chip to perform a soft-start initialization to precisely control the startup current.

Conclusion

Max16116H2307MC+ voltage supervisors are becoming increasingly popular for their reliable performance and wide application field. It is designed to provide a reset signal when the input voltage falls below or rises above a predetermined threshold. With its low on-resistance and cost-efficiency, the Max16116H2307MC+ voltage supervisor offers a reliable and economical solution in many applications.
