The MAX6388XS31D2-T is a precision, low-voltage Supervisory circuit from Maxim Integrated. It is part of Maxim\'s extensive portfolio of PMIC supervisors that includes both analog and digital options to meet the needs of a wide range of applications. This particular device, which is targeted for high-speed clocked systems requiring high performance, offers ultra-low-power reset, reset generation, and advanced reset timing features.

The MAX6388XS31D2-T is an easy-to-use, low-voltage, extendable reset controller targeted for reliable reset of complex systems, such as DSPs, microprocessors, and FPGAs. Its extended reset timing feature allows more time for power-on reset compensation, reducing/eliminating false reset events. Its adjustable reset threshold makes it applicable for range of input voltages. The device is also capable of detecting power-on-reset (POR) events including brown-out conditions.

The low-power operation of the MAX6388XS31D2-T allows the reset function to remain active while the rest of the system is in sleep mode. This is especially beneficial in mobile systems where power efficiency and heat dissipation is paramount. The device also has an adjustable hysteresis feature for debouncing, which ensures low-noise reset comparator operation.

In addition to providing accurate and reliable reset function, the MAX6388XS31D2-T also provides a power-on-reset (POR) generation feature. This allows the device to generate a reset signal when the system power is first applied, ensuring a robust power up sequence. The device also features an adjustable POR delay time feature, to provide a foolproof system turn on and turn off sequence.

The MAX6388XS31D2-T also offers an adjustable active-high or active-low output reset. The active-high output is used whenever reset signal must be synchronized with the system clock, which occurs in most high-speed systems. The active-low output can be used in single-supply applications or when access to a low-voltage external reset signal is needed.

The MAX6388XS31D2-T includes a low-power reset event (LPRESET) detection feature for rapid indication of a low-voltage reset condition. This allows the device to detect and signal a reset condition on the same clock cycle that it occurs, thus providing fast system recovery time. This allows the system to quickly react and restore its state before the reset condition occurs.

In conclusion, the MAX6388XS31D2-T is ideal for applications needing precise resetting and reset timing features. Its features ensure that it can successfully reset complex systems, quickly detect power-on-reset and low-voltage reset conditions, and generate active-high/active-low reset signals as needed. Its extended reset timing feature provides extra time for power-on reset compensation, while its low-power operations support reduced energy consumption in mobile systems.
