MCP112-290E/TO is a member of Microchip\'s Power Management Integrated Circuit (PMIC) Supervisors series. It is the Perfect IC for Designs requiring Both Overvoltage and Undervoltage Monitoring Capabilities. The power management IC family provides a cost-effective device with an industry-standard pinout in fixed and adjustable voltage versions. The device is housed in an industry-standard 8-lead SOIC package and is pin-for-pin compatible with existing industry-standard components.

The MCP112-290E/TO is a Dual Supply Supervisory Circuit featuring overvoltage and undervoltage detection and delayed reset. It is used to monitor two separate power supplies, such as a battery and wall power. The device has two independent sections, each containing a comparator, a voltage reference, and a delay timer. The OV output pin is activated when the supply voltage exceeds the overvoltage threshold, and the UV output pin is activated when the supply voltage falls below the undervoltage threshold. The active-low RESET output is delayed as determined by the delay time setting.

The MCP112-290E/TO offers reliable, low-cost monitoring of two separate supply voltages. It can be used either to protect against overvoltage or undervoltage conditions, or as a general-purpose monitoring circuit. The device can be used to monitor and protect from supply anomalies, ensure proper power sequencing, reduce power supply noise, and extend battery life. It provides a reset pulse to the microcontroller or system when the defined power up or down conditions are met.

The MCP112-290E/TO has a very flexible configuration, allowing for a wide variety of applications. It features adjustable set points for both overvoltage and undervoltage thresholds, as well as adjustable delay times for both overvoltage and undervoltage/overcurrent events. The device is typically used in battery-operated systems, automotive, portable electronics, and industrial applications. It is available in 8-pin SOIC packages and is AEC-Q100 qualified, providing reliable operation in automotive and other harsh environmental conditions.

Overall, the MCP112-290E/TO is a great solution for monitoring and protecting two separate power supplies. With its adjustable set points and delay times, it can be used in a variety of applications and environments. It provides reliable and low-cost protection against over and undervoltage conditions, ensuring the proper, safe operation of the system.
