Power Management ICs (PMICs) are integrated circuits used in various types of electronic devices for the purposes of efficiently managing and controlling power. Supervisors, one of the many functions PMICs are responsible for, feature a host of internal functions that protect systems from malfunctioning due to power faults. MAX6801UR46D2+T application field and working principle is a supervisor IC specifically used in low-power applications that require precise device diagnostics, accurate temperature control and reliable power-on reset control.

The MAX6801UR46D2+T is a dual monitor IC that offers a wide range of target voltage monitoring. Its primary function is to monitor a system’s supply voltage. Additionally, it can also monitor two remote target voltages and two remote power pins. On the 4.2V to 3.3V supply range, the MAX6801UR46D2+T provides an accurate reset and reset clear threshold of 2.6V. The device features a rising edge low voltage reset and can be used for continuous monitoring without the need for external power sequencers.

Using the MAX6801UR46D2+T, designers can take advantage of its low supply current and precise accuracy to monitor two supply rails. The device also offers two wide temperature ranges of -40°C to +125°C and -40°C to +85°C, making it perfect for low-power applications or those that are subject to drastic temperature changes. Furthermore, the IC can be powered down, allowing the design to detect the fault and switch to an alternate power source.

The MAX6801UR46D2+T includes a low power/high speed unique reset circuit that accurately monitors the VDD rail during a power-on reset. It can sense supply voltages as low as 1.8V and provide a guaranteed reset and reset clear trip voltage of 2.2V. This ensures that the reset circuit is reliably resetting the system during a power-on reset. Additionally, the reset circuit features an open-drain logic-level output stage, so the supervisory IC can integrate with a variety of different systems.

The MAX6801UR46D2+T also features extensive diagnostics on both power supply rails. This includes fault detection indicators that allow the system to identify when the target voltage is out of range, as well as enhanced temperature control for better accuracy. In temperature control mode, the supervisor can accurately sense when the temperature threshold has been reached, allowing the thermal protection of the system. Furthermore, the MAX6801UR46D2+T provides the ability to reset the system when the temperature reaches a certain threshold, and can be configured to generate an interrupt or reset the system when the temperature exceeds a pre-programmed maximum limit.

The MAX6801UR46D2+T is a highly integrated supervisor IC that provides multiple functions for low-power systems. Its low supply current and precise accuracy make it perfect for targeted voltage monitoring, and its extensive diagnostics allow for better fault detection and temperature control. Additionally, the reset features of the MAX6801UR46D2+T allow designers to accurately monitor power-on reset conditions and provide maximum safety for low-power applications.
