Power Management Integrated Circuit (PMIC) supervisors are integrated circuits that monitor and control system power states, providing independent control of multiple power systems and improved system power management. The MIC803-46D2VC3-TR is a PMIC supervisor that is specifically designed to detect undervoltage (UV) and overvoltage (OV) conditions, and provide protection to the device it is used with. In this article, we will discuss the application field and working principle of the MIC803-46D2VC3-TR.

The MIC803-46D2VC3-TR is specifically designed for applications that require continuous monitoring of power supply levels, and to provide a signal that indicates when the power supply levels have exceeded the tolerance levels. It is also designed to provide protection against overvoltage and undervoltage conditions, ensuring that the device has a safe operating range. The MIC803-46D2VC3-TR can also be used in applications that require the detection of other voltage conditions, such as inrush current and low battery voltage.

The MIC803-46D2VC3-TR features various input protection options, such as a bidirectional inrush current limiter, voltage clamping and a wide hysteresis band for high accuracy. It also features a logic controllable OV output with a maximum current of 2 mA and a UV output with a maximum current of 1 mA. The MIC803-46D2VC3-TR has an operating voltage range of 4.5V to 20V, and is available in an 8-lead VSSOP (1.27mm x 1.27mm) package.

The MIC803-46D2VC3-TR was designed for use in a wide range of applications, including power and battery management systems, automotive systems, industrial automation, consumer electronics and medical instrumentation. The MIC803-46D2VC3-TR is also ideal for use in space-limited applications, as its small package size allows it to be used in a wide variety of products and applications.

The MIC803-46D2VC3-TR provides various features for improved system power management, such as adjustable OV, UV and output trip point comparators, and programmable hysteresis levels. The adjustable OV and UV trip points can be used to set the desired system voltages, and the output trip point can be used to enable or disable the output signal. The programmable hysteresis level allows for improved accuracy by providing a noise rejection feature to prevent spurious output trips.

The MIC803-46D2VC3-TR works by monitoring the input power supply levels, and when the supply levels exceed the pre-defined trip points, an output signal will be triggered. The output signal is then used to initiate the desired action, such as shutting down the system, initiating an interrupt routine, or powering an LED. The MIC803-46D2VC3-TR can also be used to provide an indication of the health status of a device\'s power supply, allowing operators to monitor and manage the device\'s power supply more effectively.

The MIC803-46D2VC3-TR is a versatile PMIC supervisor that is ideal for a wide range of applications. It provides independent control of multiple power systems with improved system power management, and features adjustable OV, UV and output trip points with programmable hysteresis levels for improved accuracy. The MIC803-46D2VC3-TR is also an ideal solution for space-limited applications due to its small package size.
