MCP1316T-46FE/OT

The MCP1316T-46FE/OT is a supervisor integrated circuit (IC) designed for power management IC and systematic applications. It is a low-cost, low-power, advanced supervisor solution with comprehensive protection features. The MCP1316T-46FE/OT is part of Microchip\'s power management integrated circuit (PMIC) family, along with ON Semiconductor\'s supervisory device family, and is a small footprint, 10-lead, Plastic Dual In-line package (PDIP), 3.0 V ~ 10.0 V operating voltage, and 32-μA to 500-μA typical operating current. The MCP1316T-46FE/OT is designed to protect operating systems and electronic equipment by detecting voltage irregularities and resetting the system in case of over-voltage and over-current conditions. Additionally, the device provides a watchdog timer which forces the system to reset due to problems or faults in software, hardware, or data communication. The MCP1316T-46FE/OT is designed to monitor 3.0 V, 5.0 V, or adjustable+/-5% supply rails, making it an ideal choice for high-performance applications, including industrial and consumer integrated circuit products.

The MCP1316T-46FE/OT monitors up to four supply rails through internal comparators. The comparators reference an internal voltage divider, as well as external ref0 and ref1 pins to the reference circuit. When the supply voltages exceed the setpoints of the comparators, the MCP1316T-46FE/OT starts the reset timing sequence. The reset sequence does not start until the power supply voltage level drops below the reset threshold for a certain period of time. The reset delay is also adjustable through the digital bus. Moreover, the MCP1316T-46FE/OT also provides an independent reset output which allows the IC to provide indication of a reset signal to the system, allowing the system to respond to an out of tolerance voltage condition in order to protect itself.

The MCP1316T-46FE/OT is also equipped with an independent watchdog timer which helps the system recognize and respond to hardware, software, or communication faults. The watchdog timer can be used to reset the system after a predetermined period of time has elapsed. The watchdog timer can also be reset by several different reset inputs, including an external watchdog input, a supply voltage level, or a bus interface command. When the watchdog timer is triggered, it will activate the reset signal within a specified time period. This feature helps the system to quickly detect and respond to any system problems in order to protect the system from any faults.

In addition, the MCP1316T-46FE/OT also features open-drain MOSFET and pull-up device outputs to provide additional features. The MOSFET output is used to control external power supplies or enable devices. The pull-up device output, when enabled, pulls up or down specific logic levels depending on the logic level of the supplied power. The device is also designed to support two operating modes: active and clear. The active mode allows the IC to detect high and low voltage levels. When the voltage level reaches the prescribed threshold, the IC will start the reset timing sequence. On the other hand, the clear mode is used to clear any latched circuits and reset the watchdog timer. This helps to keep the system under control and prevent any unintended operations.

Overall, the MCP1316T-46FE/OT provides a host of features to provide reliable protection for integrated circuit applications. It includes features such as on-chip voltage detection, reset timing for over-voltage and over-current conditions, an independent reset output, and an independent watchdog timer. Additionally, it also includes open-drain MOSFET and pull-up device outputs to provide additional features. The device is a small footprint 10-lead PDIP package in the power management IC family. This makes it ideal for high performance applications, including industrial and consumer integrated circuit products.
