PMIC Supervisors are a type of integrated circuit (IC) which is used to manage power systems and supervise their operation. The MCP131-195I/TO is one such device and serves to monitor voltage levels and either shut off or activate other system components when certain conditions are met. This makes it a useful tool for ensuring systems remain in a desired state and allows for more accurate control over system outcomes. This article outlines the application field of the MCP131-195I/TO and its working principle.

The MCP131-195I/TO is a voltage supervisory IC specifically designed for use in microcontroller or digital logic systems. It works in association with an externally supplied reference voltage and can be configured to either generate a reset or interrupt signal during undervoltage or overvoltage conditions. This is important in order to ensure the system remains operational even in the event of power failure or voltage spikes. The device is typically used in automotive, industrial and consumer systems in order to protect systems from unexpected power fluctuations or unexpected changes in the operating environment.

The MCP131-195I/TO comprises two distinct blocks: a Delta-Sigma A/D converter, and a power on reset generator. The A/D converter provides an analog voltage reference to the device, which is compared against a factory set threshold voltage. If the voltage dips below or rises above this threshold, the device will trigger either a reset or interrupt signal depending on the user configuration. This makes the device capable of responding to spikes or changed conditions in the power supply and engaging shutdown/shut-on actions in order to preserve system integrity.

In addition to its voltage supervision capabilities, the MCP131-195I/TO also provides additional protection against overcurrent and reverse polarity conditions through its integrated fault detect circuitry. This ensures the system remains operational even under difficult conditions, allowing for more reliable systems without the need for additional protection components. As the device is a dual function IC, it is capable of performing both voltage monitoring and fault detection in the same package. This reduces complexity and provides users with a single solution for their voltage supervision needs.

The MCP131-195I/TO is a low-power, low-voltage supervisor which is ideal for use in embedded, microcontroller and digital logic systems. Its fast response time and wide range of triggering thresholds make it a versatile device capable of providing reliable protection to power systems even in harsh or demanding conditions. Its integrated fault detect circuitry provides additional protection against overcurrents and reverse-polarity, while its low power consumption allows the device to be used in a wide range of applications. With its versatility and reliable performance, the MCP131-195I/TO is a valuable addition to any power system.
