The MAX16086AXS29B+T is a versatile, precise, low quiescent current, fixed output voltage, ultra-low supply supervisor for microprocessor system that packs many features into a very small package. It is part of the PMIC – Supervisors family.

The MAX16086AXS29B+T is designed to protect microprocessor-based systems, including microcontrollers and digital signal processors, against multiple power supply faults. It is ideal for embedded applications as it requires just small size, as well as its low power consumption and advanced features. This device features an ultra-low supply current (<10µA), and a low voltage-drop reset output.

The device monitors power supply rails using an integrated series pass FET and an adjustable threshold detector. It can detect faults in the secondary power supply rail, such as short-circuit, undervoltage conditions and the device can be tweaked for different logic levels. It also has an integrated timeout delay-(Inactive Power Controller) for turning off on-board electronics or powered components that require multiple power rails.

The MAX16086AXS29B+T is an ideal supervisor for high-end embedded systems. It has a wide operating temperature range from -40°C to +125°C and it offers significant power savings compared to conventional linear regulators. In addition, this device provides with the required flexibility to meet a variety of requirements of embedded applications. The MAX16086AXS29B+T is highly configurable in terms of reset parameters, thresholds, and response time.

The device features an adjustable reset delay output window. This allows for an order of magnitude increase in the reset delay time (up to 30 ms) for fault-sensitive applications. This feature also allows for administrator’s configurable reset windows to be programmed prior to device installation in the system.

The MAX16086AXS29B+T has multiple protection features including a forbidden voltage range that disables the supervisor and input monitoring during pre-start-up and initial system configuration. It also has an emergency power-off function that provides direct system shutdown. The emergency power off feature can be triggered by undervoltage, overvoltage, or a combination of the two. It is worth noting that the alarm output acts as the power failure indicator and can be used to signal other system components of the occurrence of a power fault.

The MAX16086AXS29B+T application field allows the device to be used in a variety of systems, from handheld devices and personal electronics products such as phones and tablets, to automotive systems and industrial applications. The device can also be used for primary and secondary power supply monitoring, embedded controllers and microprocessors, embedded power supplies, cell phone chargers or any device that requires power monitoring. The device can work with input voltages ranging from a 2.7V to 4.8V and 3V, respectively.

The MAX16086AXS29B+T working principle involves both the detection of power supply faults, as well as the generation of a reset signal when a fault is identified. The device is designed to monitor a supply rail, and when the voltage level drops below a preset voltage level, the device will generate a reset signal. The reset signal is active-low type and can be used to reset the microcontroller, as well as any other device that needs to be reset in the event of a power fault. The MAX16086AXS29B+T employs an adjustable reset delay timer, which indicates the time between when the fault begins and when the reset signal is generated. This feature allows the device to be used in applications that require a longer delay before the reset signal is generated.

Overall, the MAX16086AXS29B+T is an efficient and reliable power supervisor for monitoring and controlling power supply rails. It offers significant advantages in terms of size and operating efficiency, as well as its robust fault detection and reset delay abilities. This device is ideal for any system that requires protection against multiple power supply faults, and its application field and working principle make it an ideal choice for many embedded and power supply monitoring applications.
