PMIC – Supervisors are electronic circuits usually embedded within very small controllers. They are specifically designed to detect system errors or failures in processing or performance of integrated circuits. The purpose of the system supervisor is to provide a reliable and consistent error detection mechanism to ensure the system is able to perform its functions properly. The MAX16040LLA29+T is one of the latest PMIC supervisors to enter the market. This article will discuss the application fields and working principle of the MAX16040LLA29+T.

The MAX16040LLA29+T is an ultra-low power, single-supply voltage supervisor circuit that has a wide range of applications. It can be used in various systems that require a reliable monitoring of fault conditions such as automotive systems, home networking, industrial control, and telecom systems. The MAX16040LLA29+T is designed to provide early detection of power supply transitions, power supply failure and system reset. It also provides a simple, low-cost way to detect system-level failure conditions and trigger associated timing operations.

The MAX16040LLA29+T works by continuously monitoring and comparing an on-board reference voltage to an external voltage source. When the on-board and external voltages fall below a certain threshold, it triggers an active-low RESET output, allowing the system to reset. The RESET output is held active until the voltage sources are restored to their normal value. This ensures system integrity is maintained and errors or glitches are identified in a timely manner.

The MAX16040LLA29+T also includes six comparator logic outputs (0V-L, 0V-H, 1V-L, 1V-H, POR-L, and POR-H). The 0V-L and 0V-H are active-low and active-high outputs, respectively, used for monitoring the supply voltage of 0V and 0V systems. The 1V-L and 1V-H comparators indicate when the supply voltage has dropped to 1V and 1V, respectively. This is useful for detecting brown out conditions. The POR-L output is active-low and indicates when the power-on reset has occurred. Finally, the POR-H output indicates when the supply voltage is greater than 5.5V.

The MAX16040LLA29+T also includes two optional timer outputs (TIM1, TIM2). These can be used for time-based monitoring of voltage levels such as debouncing, brown out detection and inrush current limiting. The timers consist of an adjustable resistance, a capacitor, and a comparator. The resistance and capacitor are adjusted to specify the time intervals for the timers to start and/or stop. When the timer is triggered, the output voltage from the comparator is generated. This can be used to provide an alert to external circuitry.

In summary, the MAX16040LLA29+T is a low-power, single-supply voltage supervisor circuit with a wide range of applications. It is designed to provide early detection of power supply transitions, power supply failure, system reset, and timer outputs for timing operations such as debouncing, brown out detection and inrush current limiting. It is suitable for systems that require a reliable monitoring of fault conditions such as automotive, home networking, industrial control, and telecom systems.
