Power management integrated circuits (PMICs) are used by system designers to reduce the complexity of systems. As such, PMICs can help reduce system size, cost and improve energy efficiency. A type of PMIC, Supervisors, often referred to as System-Level Reset Circuits, are used for safety monitoring, as well as for protecting against power-on reset (POR) and brown-outs. The MIC803-46D3VM3-TR is a low cost Supervisor IC used in many consumer and industrial electronics.

The MIC803-46D3VM3-TR is a 3.0 Volt CMOS powered Supervisor IC designed to protect against a supply voltage drop, or brown out, and to monitor the microprocessor system\'s reset signals. It simplifies reset circuit design by combining a reset controller and power-on reset diode protection circuitry into one circuit. It can also be used to eliminate a dedicated reset circuit. The MIC803-46D3VM3-TR ensures that the system is properly reset after a brown out or other error condition. It will reset the system when the power supply voltage drops below a certain value, typically 1.85V. It helps ensure that the system returns to normal operation after a brown out.

The MIC803-46D3VM3-TR can detect microprocessor failures and recover the system by resetting it. The device uses an internal timer to generate a reset signal if the microprocessor does not recover within a predetermined amount of time. The Reset output signal can be used to disable the system and reset the microprocessor. It will also disable any other circuits that may be adversely affected by the brown out.

The MIC803-46D3VM3-TR also has 5 general-purpose I/O pins that can be used as digital inputs or outputs. The general-purpose I/O pins can be configured as either open drain outputs or latched inputs, depending on the application. This enables the Supervisors to adapt to a variety of system requirements.

The MIC803-46D3VM3-TR is an ideal reset circuit for a variety of applications. Its low cost and simple reset circuit design makes it a great choice for most applications. It can also be used as a system watchdog, to ensure the processor is always running properly and prevents lock-ups. In addition, the MIC803-46D3VM3-TR is compatible with a wide range of processors and can be powered with a 1.8V to 3.6V supply.

The MIC803-46D3VM3-TR is an ideal choice for any application or system requiring a reliable reset circuit. By combining a reset controller and power-on reset diode protection circuitry into one circuit, it simplifies reset circuit design. In addition to reset circuit applications, the MIC803-46D3VM3-TR\'s general-purpose I/O pins can be used as digital inputs or output. It is a low cost, easy to implement Supervisor IC that is compatible with many processors and can be powered with a wide supply voltage range.
