Power Management Integrated Circuits (PMICs) are devices embedded in circuits to regulate the power used to drive components and modules. One type of PMIC, supervisors, are used to protect the connected peripheral from damages caused by over-voltage, low voltage, over-current and reverse polarity. The MCP1319MT-26EE/OTVAO is a supervisor PMIC that is commonly used to protect circuits from external power failures and to keep them operating at a constant voltage. This article will discuss the application fields and work principle of the MCP1319MT-26EE/OTVAO.

The MCP1319MT-26EE/OTVAO is most commonly used in power protection circuits and power management systems. It uses a Wide VIN Range (3.3V to 27V), allowing it to be used in a variety of DC applications ranging from small portable electronic devices to industrial grade circuits. The Over Voltage Protection (OVP) feature of the MCP1319MT-26EE/OTVAO allows it to protect connected peripherals from excessive voltage surges, ensuring their longevity and normal operation. The Over Current Protection (OCP) feature of the MCP1319MT-26EE/OTVAO also helps to protect connected peripherals from excessive current, controlling the current drawn and eliminating possible circuit damage due to high currents. One of the most important features of the MCP1319MT-26EE/OTVAO is its Reverse Polarity Protection (RPP) feature, which prevents reverse current from flowing from the connected peripheral to the circuit, protecting it from possible damage.

The MCP1319MT-26EE/OTVAO is a compact and efficient PMIC that can be used to protect circuits and peripherals. It has an Efficiency rating of 88%@3.3Vin, making it very energy efficient. The Drop Out Voltage is only 0.35V@1A, meaning that when the MCP1319MT-26EE/OTVAO is in operation, there is minimal power loss. The device also has a minimum operating current of 0.6uA typical which helps reduce power consumption even further. The Output Voltage (Vout) of the MCP1319MT-26EE/OTVAO can be adjusted from 0.3V to 6V with a Programming Voltage (VP) of 0.1 to 5V. The MCP1319MT-26EE/OTVAO is available in 3 different packages (SOT-23-5, SSOP-14,MSOP-10) to fit different applications.

The MCP1319MT-26EE/OTVAO works by constantly monitoring the input voltage level and triggering an Over Voltage Protection (OVP) or Over Current Protection (OCP) signal when the voltage or current exceeds a user-defined threshold. The OVP signal triggers a comparator that releases a bi-directional latch, preventing the output voltage Vout from rising more than the allowed voltage (VAOVP). The OCP signal triggers a comparator that releases a bi-directional latch, which in turn limits the output current. The device also contains Reverse Polarity Protection (RPP) which prevents reverse current from flowing from the connected peripheral to the circuit.

In conclusion, the MCP1319MT-26EE/OTVAO is a compact and efficient PMIC supervisor that can be used in a variety of DC applications. It has wide input voltage range, efficiency rating of 88%, drop out of 0.35V@1A, and its output voltage is adjustable from 0.3V to 6V. The device also contains OVP, OCP and RPP features, allowing it to protect the connected peripherals from damages. The MCP1319MT-26EE/OTVAO is available in 3 different packages, SOT-23-5, SSOP-14, and MSOP-10.
