PMIC (Power Management Integrated Circuit) is an important component in modern electronic devices, playing a critical role in controlling the power and energy efficiency of a device. Supervisors are a class of PMICs that monitor the power and reset signal levels, preventing system reset malfunctions. The MAX6452UT26L+T is a supervisor IC designed for monitoring negative and positive power rails in systems that require a nominal voltage of 2.6V, such as low-voltage ICs.

The MAX6452UT26L+T employs a three-state power-good flag. It simultaneously monitors both positive and negative power rails, with a hysteresis voltage window of 0.75V centered around the nominal voltage of -2.6V for the negative rail and 2.6V for the positive rail. This ensures that it does not accidentally deactivate due to a large power spike or voltage drop.

The MAX6452UT26L+T can be set to trigger an assertion or de-assertion output upon the crossing of the predetermined trip points. This configurable feature allows the user to choose between a resetting or non-resetting circuit. The power-good output is de-asserted when the voltage is beyond the thresholds, providing safety devices with an accurate voltage-monitoring window.

Additional features of the MAX6452UT26L+T includes an integrated fault timeout circuit. This ensures that the part does not remain active after a fault has been detected. The fault timeout circuit delays the response of the circuit to reset signals, avoiding false resets due to brief voltage drops or spikes. Furthermore, the MAX6452UT26L+T has an adjustable reset delay that can be set to the ideal value for the application.

The MAX6452UT26L+T is a low-power, space-saving supervisor IC that is ideal for applications that require accurate monitoring of power rails. It is available in a 6-pin, small outline package and is designed to consume minimal power. The MAX6452UT26L+T is ideal for use in portable devices, digital media players, consumer electronics, and a wide range of other applications.
