MAX6386LT26D3+T

PMIC - Supervisors

The MAX6386LT26D3+T is a member of Texas Instruments\' PMIC (power management ICs) Supervisors family. It is designed to provide power monitoring, sequencing and protection over the dual-rail supply rail. It has built-in advanced features such as ultra-low power-up/down sequencing and over/under-voltage protection. The device also features digital delay measurement, which allows designers to accurately ensure sequencing of multiple power rails under conditions of high transients or changes in system power consumption.

The device is used to manage, monitor and protect the power rail across multiple applications, such as in digital video recorders, set-top boxes, embedded systems and automotive systems. It has a full range of features including simple on/off sequencing, over/under voltage headroom, fault detection and shutdown as well as constant current and voltage monitoring. The device can also be used to monitor multiple secondary rails such as 3.3V and 5V rails. It is designed to operate in harsh environments and provides some of the highest levels of protection available for system applications.

The MAX6386LT26D3+T includes two independent supervisors (over-voltage and under-voltage supervisory functions) capable of both high and low power-up/down sequencers. The device provides an adjustable fault level reset (FWR) function, which can prevent uncontrolled cycling of the system during power-up. This adjustable voltage setting is programmed via an external resistor. The device also features the industry\'s fastest response times, providing protection against short term power faults.

The MAX6386LT26D3+T\'s dual-rail protection is designed for smooth power switching when one of the rails shifts to a higher or lower voltage level. This prevents glitches on the rail when one of the two rails shifts in voltage level. It is designed to provide protection from over-voltage conditions that could damage the system.

The MAX6386LT26D3+T features an advanced power-saving mode, called "StandbyOff," which enables the device to monitor the system power rail while expending minimal power. This mode allows the system to remain operational while still providing optimal protection. The device is small and efficient and meets the stringent requirements of many industrial and automotive applications.

In summary, the MAX6386LT26D3+T is an excellent choice for applications requiring power monitoring, sequencing, and protection. It provides advanced features such as ultra-low power-up/down sequencing and over/under-voltage protection and digital delay measurement, as well as a standby-off mode for power savings. The device provides quick fault detection and can power down the system in the event of a fault. It is designed to meet the very stringent requirements of many industrial and automotive applications and is a perfect choice for these types of applications.
