The MAX6316LUK46CZ-T belongs to the category of PMIC–Supervisors, which are integrated circuits (ICs) designed to supervise power supply systems in embedded electronics. It is a precision, low-power 3-channel supervising IC from Maxim Integrated, offering over-voltage, under-voltage and reset functions for embedded microcontroller systems. To guarantee the correct operation of a system, Vital Parameter Monitoring (VPMS) is required. The MAX6316LUK46CZ-T is the perfect solution to fulfil those needs.

The voltage supervisor ICs guarantee the system operation in a wide range of operating conditions. It gives users the confidence that their systems are protected from inrush current, as well as from any other unexpected events. The extensive product range also allows a cost-optimized solution. The wide input voltage range of the MAX6316LUK46CZ-T allows it to be used in any application that needs a reliable, precision, low-power supervisor circuit.

The MAX6316LUK46CZ-T is designed to monitor multiple power supply domains, with consideration for applications that have mixed power domains. It is available in SOT-23-5, 6-bump uDFN and chip-scale packages, allowing for ultimate optimization. It is best suited for embedded microcontrollers and microprocessors, automotive systems, industrial/building automation, and other equipment that require a reliable reset signal.

The MAX6316LUK46CZ-T employs a powerful feature set for applications that require EVP protection without the need for external components. It has three precision, integrated voltage reference points: a low-voltage reset output, a reset assertion voltage point, and an over-voltage detection point. This eliminates the need for multiple complex components, thus reducing overall system cost. Beyond the main features, it also supports an automatic power-on reset (POR) function, a manual reset input, a toggle-mode reset output, and an active-low active-high reset output. These features provide flexibility in configuring the reset control circuit.

The working principle of the MAX6316LUK46CZ-T is that, when the input operating voltage rises above the reset assertion voltage (RSTA) point, the over-voltage detection circuit (OVD) issues an alert signal. This alert signal can be used to generate an instantaneous reset signal for the system. If the input voltage drops below the active-low reset output threshold, the reset output turns low, causing the microcontroller to enter a reset state. If the input voltage rises to an above-threshold level, the reset output is pulled high, allowing the microcontroller to continue with normal operation.

The MAX6316LUK46CZ-T is a superior choice due to its many features. It offers precise over-voltage and under-voltage protection, it is able to automatically reset the system if the power supply is interrupted, and it can be used in a wide range of applications. It is also very cost-effective, as it does not require additional external components. The wide operating temperature range, small package, and single-supply operation make the MAX6316LUK46CZ-T the ideal choice for many embedded applications.
