The MCP100-450HI/TO is a supervisory component of a PMIC (Power Management Integrated Circuit). The component provides fail-safe reset and power management in a system. Supervisory components like the MCP100-450HI/TO are used in many applications including embedded systems, communication and consumer electronics.

The MCP100-450HI/TO is designed for protection against loss of power, brown-out conditions, short circuits and unintentional reset. The component has an on-chip voltage monitoring circuit that is kept active even when power is lost. The component has an adjustable threshold voltage (Vth) that can be set to any level between 1V and 4.50V. The voltage is monitored against the adjustable Vth and a pull-up resistor. An active-low reset output called RESET_L is generated when the voltage level falls below the Vth. The RESET_L signal sent to the reset-input of the system is held active as long as the voltage on the power supply is below Vth.

The threshold voltage can be adjusted to meet the specific needs of the system. A precision reference voltage can also be used to accurately set the Vth. The MCP100-450HI/TO also has an input from the system called keep-alive. The keep-alive signal can be used to extend the reset time during a power fault. Without the keep-alive signal the reset signal remains active until the fault conditions are cleared.

The MCP100-450HI/TO is an ideal component when precise power monitoring is required. The adjustable Vth and keep-alive input make it ideal for a wide range of applications. The component is offered in a 5-pin SOT-23 package which is compact and easy to use. The component is also energy efficient and has a low current consumption of just 0.5µA.

In summary, the MCP100-450HI/TO is a high-performance supervisory component for PMIC solutions. The adjustable Vth and keep-alive inputs provides reliable, precise power monitoring. The component is ideal for embedded systems, communication and consumer electronics.
