MAX6387XS22D3+T is the latest model in the MAX6387X Supervisors family. It is a PMIC (Power Management Integrated Circuit) module specifically designed for mobile device applications and other ultra-low-power applications. The device brings a high level of flexibility and reliability to embedded designs, allowing designers to meet their demanding applications without compromising on either power consumption or system performance.

The MAX6387XS22D3+T offers two distinct functions in the application field. First, it provides a high-accuracy supply voltage monitor for detecting voltage faults that may otherwise go undetected. This feature helps ensure reliable system performance and also allows for higher levels of integration when designing systems with multiple power sources. The second function is a highly-efficient watchdog timer, which is used to detect and recover from system faults.

The MAX6387XS22D3+T also features an integrated power-on-reset (POR) circuit, which helps provide protection from power on/off transients. In addition, it offers a unique sleep-mode detection circuit, which is ideal for low-power applications by detecting and reporting sleep-mode status changes within the system. Finally, the device also offers advanced fault management capabilities, including a programmable reset polarity and filtering, over-voltage/under-voltage protection, temperature-compensated voltage monitoring, and a programmable output drive capability.

The MAX6387XS22D3+T provides power management functions in two distinct modes, each of which can be adjusted to meet the specific requirements of a given application. The first mode is the standby mode, where the device monitors the power supply voltage and issues reset signals when the voltage exceeds a predetermined threshold. The second mode is the run mode, in which the device powers up all internal components and allows the system to enter into active operation. Both modes feature built-in protection functions, including an over-voltage/under-voltage protection circuit, temperature-compensated voltage monitoring, and a programmable output drive capability.

The device’s advanced fault management capabilities also help ensure reliable system operation. Its programmable reset polarity and filtering allow reset signals to be sent to the system’s power-on-reset circuit on user-defined thresholds, and its over-voltage/under-voltage protection circuit helps limit system damage during power faults. The integrated sleep-mode detection function helps signal system transitions into low-power states, while the programmable output drive capability facilitates system start-up and shutdown functions.

Thanks to its easy integration, flexibility, and reliable fault management features, the MAX6387XS22D3+T is ideally suited for applications requiring reliable power monitoring or watchdog timer solutions. Its features make it an excellent choice for embedded applications, particularly in mobile and ultra-low-power systems.
