PMIC, or Power Management ICs, are integrated circuits that help manage power within electronic systems and devices. A typical PMIC incorporates a range of power management functions, including converting between different power sources, managing battery charging, handling power sequencing and distribution, and providing system monitoring functionalities. Supervisors are an important sub-category of PMICs that provide the primary interface between the power source and the loads. In this article, we will discuss the application field and working principle of the MAX6755UKTD0+T supervisor.

The MAX6755UKTD0+T device is a low-cost, low-power supervisor IC with four Digital Inputs (DINs), one analog comparator input, and one output power switch. It is designed to monitor power supply voltages and ensure reliable system start-up and safe system shutdown. This device also features low-voltage monitor (LVM) capability with a selectable trip point and provides hardware reset delay of up to 150 milliseconds. This supervisor is ideal for battery powered systems where small quiescent current, low output voltage drops, and large reset delays are required to optimize battery run-time.

The MAX6755UKTD0+T supervisory devices can be used to monitor the system power supply and reset the system if the power supply is out of tolerance. It can also be used to monitor the battery voltage and reset the system if the battery voltage drops below a certain level. The device features a low-voltage monitor (LVM) with a selectable trip point and can provide hardware reset delays of up to 150 milliseconds. This allows the device to effectively shutdown components before battery run-time is exhausted. Additionally, it also features a selectable output voltage, so it can be used to interface with 3.0V, 3.3V and 5.0V logic.

The MAX6755UKTD0+T works by first comparing a voltage level on one of the DINs to the analog comparator input. If the DIN voltage is higher than the threshold set by the analog comparator, then the output is enabled and the reset signal is generated. This reset signal is then delayed by a predetermined value, allowing the system to perform any necessary shutdown functions before the system is reset. Additionally, if any of the DINs are at a lower voltage than the threshold, then the reset signal is generated immediately, bypassing any reset delays. This allows the device to quickly reset the system if necessary.

The MAX6755UKTD0+T supervisor has found wide application in battery-powered embedded systems where efficient power management and reliable system start-up and safe system shutdown are required. It has also been used in industrial electronics, automotive and avionics systems, and consumer electronics. This device is preferred by many engineers because of its low power consumption, small size, and selectable trip point and reset delay features.

In conclusion, the MAX6755UKTD0+T supervisor is an ideal device for a variety of applications requiring reliable system start-up and safe system shutdown. Its low-voltage monitor (LVM) and selectable trip point feature makes it an efficient tool for battery-powered applications. Additionally, its selectable output voltage and hardware reset delay capabilities make it an ideal choice for interfacing with higher voltage logic systems.
