PMIC (Power management Integrated Circuits) are a form of electronics which specializes in the management of both power and voltage. Supervisors refer to specialized components which act as supervisors and controllers of the power management. MCP101T-460I/TT is one such supervisor IC from the MCP101T series. This device is typically used for the design of power supply supervisors for battery or non-volatile RAM (NVRAM) backup in low-power applications. It has a wide variety of features which make it desirable for fields including industrial control systems, instrumentation, automotive applications and more. The working principle behind the MCP101T-460I/TT lies in its monitoring and detection function capability. This IC can be used to monitor the power supply design during a shutdown. It monitors and detects the supply rail voltages at two levels – undervoltage lockout (UVLO) and brown-out shutdown (BOD). The UVLO feature allows users to configure the undervoltage threshold and hysteresis to obtain maximum system stability. This feature is important for preventing power supply oscillations. The BOD feature detects when the power supply has fallen below the brown-out threshold specified by the user. This helps prevent errors due to data corruption when the power supply is unstable or too low. Uniquely, this IC also has an integrated reset controller which enables users to overcome additional challenges posed by unstable power supply conditions. This reset controller allows the user to program the reset time delay, reset active high/low, reset type and the reset threshold. What makes MCP101T-460I/TT even more attractive is its hardware watchdog timer. This timer helps prevent system hang-ups due to code error by monitoring the occurrence of specific control signals. It allows the user to program the timeout period, timer clear source, timer write source and reset type depending on the system design. The integrated MCP101T-460I/TT allows users to easily configure and monitor the power supply design during a shutdown. It has a wide variety of features, such as the integrated reset controller, hardware watchdog timer and the UVLO and BOD functions, which makes it desirable for fields such as industrial control systems, instrumentation, automotive applications and more.
