The MAX6388XS22D5-T is a tiny, inexpensive, active high–side, current-limit supervisor from Maxim Integrated Products. It is a member of the MAX6388 family of programmable high-side current-limit supervisors. This device is a drop-in replacement for 4-channel versions of the MAX6385 family and can replace 3-channel soic-8 packages in space-constrained applications. It has a 2.2V reference-level reset threshold.

PMIC - Supervisors Application - The MAX6388XS22D5-T

The MAX6388XS22D5-T is designed to monitor and protect multiple systems in automotive, industrial, and consumer applications. It is an ideal solution for applications that need a low-cost, highly accurate push-button reset solution.

The device offer accurate under voltage and brownout protection with a low quiescent current of 4 μA. It ensures that the system has a low on resistance, is low-noise, and does not require external components.

Working Principle

The MAX6388XS22D5-T contains multiple comparators and voltage references. It is used to monitor and protect multiple systems. The device checks the voltage of the system and triggers a reset once the voltage falls below the reset threshold. The device also contains a UVLO (under voltage lockout) to protect the system from being damaged when the voltage falls below a certain value.

It also has an adjustable current limiting feature. This feature is used to protect the system from overcurrent faults. The adjustable current limit feature allows the user to set the maximum current for the protected load.

The MAX6388XS22D5-T also contains a power-good output. This output monitors the reset threshold and signals a valid reset when the threshold is exceeded. It also has a programmable reset time-out feature. This feature allows the user to adjust the maximum time the reset signal remains active.

The MAX6388XS22D5- T is designed to provide reliable protection in a variety of applications. It is a rugged and low-cost alternative to traditional protection schemes. It is suitable for use in automotive, industrial, and consumer applications.
