PMIC - Supervisors are integrated circuits for monitoring input power supplies. The purpose of PMIC - Supervisors is to insure proper power-up and power-down behavior of a system, to protect for fault conditions, and to protect against brown-outs. The MAX6318MHUK46CY-T is one such PMIC - Supervisor from Maxim Integrated Products.

The MAX6318MHUK46CY-T is a low power microprocessor supervisor with push-pull manual reset and Power-On Reset (POR) functions. This microprocessor supervisor is a single-channel device that allows per-channel timing settings. It is an ideal choice for a wide range of low power system management applications, such as monitoring battery voltage in an energy storage system, monitoring power module voltage and current in a motor drive system, and in microprocessor based systems.

The MAX6318MHUK46CY-T incorporates functionality that provides system management functions such as supplying start-up voltage, managing the time delay of system reset, resetting after a power failure, controlling the input power supply under feedback from the application circuit, monitoring the voltage and current of each power rail, and resetting after a voltage failure or other operational problem.

This device provides a manual reset (MR) input, a power-on reset (POR) output, and can be used for precise power monitoring. The MR works in conjunction with the hardware reset control logic, so that a hardware reset can be asserted after a specific event. The power-on reset (POR) output provides an externally resettable circuit that is based on the device\'s internal trip voltage (VTRIP) and its input power supply voltage (VCC).

The MAX6318MHUK46CY-T can be used to protect against power supply surges, brownouts, and voltage drops. The device features a wide input voltage range of 1V up to 5.5V, fast power up and down times of only a few milliseconds, detection level accuracy to ±2.5%, and wide hysteresis range up to 6.25V. The MAX6318MHUK46CY-T is also highly configurable, with an operating temperature range of -40°C to +85°C, integrated over-temperature protection, and integrated hardware monitoring.

To ensure correct operation, the MAX6318MHUK46CY-T has been designed to provide a firmware-selectable maximum turn-on and minimum turn-off voltage, as well as a minimum current and programmable power-up supervision delay. Additionally, there is an output that indicates when the input voltage is below the VTRIP setting. These features along with several other timer functions allow for maximum flexibility and control when monitoring voltage, current, and temperature levels.

The MAX6318MHUK46CY-T is suited for a variety of applications in industrial, consumer, automotive, and communications devices, where strict voltage and current monitoring are needed. For example, in applications such as automotive power systems, this device can be used to protect the system from over-current and current leakage, providing dependable and reliable power protection. Similarly, in industrial automation applications, the device can be used to monitor voltage and current levels of multiple power modules for safe operation. In electronic communication and consumer electronics, this device can provide protection from harmful voltage spikes.

The MAX6318MHUK46CY-T is an easy-to-integrate integrated circuit that provides an excellent solution for a wide range of low power system management applications. It provides the necessary support for proper power-up and power-down behavior of a system, while protecting against fault conditions and brownouts. With its wide input voltage range, fast turnaround times, detection level accuracy, and hysteresis range, the MAX6318MHUK46CY-T should be considered for any application that requires a highly configurable and reliable power management IC.
