A supervisor is an integrated circuit typically used to monitor microprocessor-based systems for the purpose of detecting and recovering from an erraneous condition. The MIC6315-42D3UY-TR is a high performance supervisory circuit with an integrated, reset generation circuit and a supply voltage supervisor. It is available in a small SOT-23-5 surface mount package, making it ideal for space constrained applications.

The MIC6315-42D3UY-TR is designed to monitor low-voltage, positive-voltage, and battery-powered systems. It can detect power-on reset (POR) and general reset signals, brownout detection, and voltage-dropping faults. The MIC6315-42D3UY-TR ensures that the microprocessor-based systems in which it is embedded will reset properly to initial settings, preventing further faults or damage to sensitive parts.

The MIC6315-42D3UY-TR includes an incorporated Reset Generator, which produces a reset signal when an aberrance is detected. The Reset Generator is comprised of two low-power buffers, a comparator, and a debouncing circuit; it monitors the system’s supply voltage for out-of-tolerance conditions and initiates a reset when its voltage drops below a predefined threshold. The Reset Generator serves two purposes: 1) preventing further decreases in voltage and 2) reinstating system settings to their default settings.

The MIC6315-42D3UY-TR also features an integrated Supply Voltage Supervisor (SVS). It continuously monitors the system’s supply voltage and compares it against a defined threshold. If the supply voltage remains above the threshold, the SVS is disabled, otherwise, it will initiate a reset when the voltage falls below the threshold.

The MIC6315-42D3UY-TR is tailored for use in mobile/portable applications since it requires very low supply current consumption and few components. Its low operating power requires minimal external components and allows it to operate on small and low capacitance power supplies. Additionally, it is suitable for battery-operated systems, as it will enter a low-power sleep state when the supply voltage is low and the system is inactive.

The MIC6315-42D3UY-TR is designed for mobile, communication, and consumer equipment, and is compatible with 3.0V devices. The circuit is optimized for extremely low-input capacitance to minimize noise susceptibility, and it offers very low-power consumption and high accuracy. Furthermore, it provides a wide range of temperature operating range, meaning it is suitable for operation in extreme or variable temperature environments.

In summary, the MIC6315-42D3UY-TR is a high-performance supervisory circuit specifically designed for mobile, communication, and consumer equipment. It provides a reset generation, supply voltage supervision, and battery management services. It can detect power-on reset and general reset signals, brownout detection and voltage-dropping faults. It requires minimal external components and offers low supply current consumption and very low-power consumption. Additionally, the MIC6315-42D3UY-TR is optimized for extremely low-input capacitance, offering a very wide temperature range.
