PMIC (Power Management Integrated Circuit) is a complex multi-functional circuit that integrates one or more integrated circuit components into a single package to manage the functions of various autonomous operating power applications. Supervisors are a type of PMIC used to provide authentication and control during system startup, as well as other time-sensitive operations. The MAX16086US27E+T is a high performance supervisor device offering fast initialization, high accuracy, and a low standby quiescent current.

The MAX16086US27E+T is an ultra-low-dropout (LDO) voltage supervisor intended to monitor and alert system functioning. It provides fast response time, accurate monitoring of rail voltages, low supply current consumption, and can detect pull-down/pull-up faults. The device is available in a 5-pin SOT-23 package and operates in temperatures ranging from -40 °C to 85 °C.

The MAX16086US27E+T can be used to provide system voltage monitoring for low-power applications such as portable industrial equipment and portable medical devices. It is also suitable for brown-out monitoring of digital systems in consumer and automotive applications. Other applications include medical devices; motor, robotics, and automation controllers; smart meters; and industrial evaluation modules.

In general, the MAX16086US27E+T monitors a system voltage, such as a 3.3V power rail, and asserts a reset signal when the voltage drops below a predetermined threshold. The reset signal will reset the system on power up or during operation when the voltage level falls below a threshold. The MAX16086US27E+T also provides a watchdog timer to ensure system stability. The watchdog timer monitors the activity of the system and, if the system becomes unstable, will reset the system. The reset signal is debounced to prevent false triggers.

The MAX16086US27E+T features an accuracy of ¬±1.5% that enables a precise monitoring of the system rail voltage. The maximum supply current consumed is 4.4µA providing an ultra-low-power operation with no extra components. The integrated LDO provides users with a low dropout voltage. This eliminates the need for external linear regulators and provides wide flexibility in reset threshold settings.

In addition to voltage monitoring, the MAX16086US27E+T offers an open-drain MOSFET driver for reset generation. This allows for extending the reset line to long distances, inducing a low propagation delay, and providing a superior noise immunity. The reset threshold is set to a default value of 2.905V ±1.5% though and an external capacitor can be used to set the reset threshold voltage at any desired level.

The MAX16086US27E+T provides superior protection to a system, while also providing flexibility and accuracy. Its wide range of operating temperature, low quiescent current, and low-dropout voltage make it an excellent choice for applications operating in harsh environmental conditions. Its small size and high accuracy make it ideal for many applications and systems.
