The MXD1813UR46+T IC is a PMIC – Supervisors IC that has a wide range of applications in a variety of industrial and consumer applications. This device is well known for its superior performance and it is an ideal choice for applications that need high precision monitoring, protection, and control.

The MXD1813UR46+T is a low power 3V supervisory circuit that operates over an operating range of -40°C to 85°C. It features a true voltage monitor, which is capable of monitoring supply voltage within a range of 2.9V to 5.5V. An integrated protection circuit consisting of three phases of protection for over temperature, over current, and over voltage as well as Under Voltage Lock Out (UVLO) protects both the device and application from damage caused by over/under voltage, over current and over temperature.

The device supports very low standby currents and a Noise Immunity (NMI) input to reject signal noise pulses beyond 0.2V. It also features an Accurate Reset Timer (ART) mode which enables an adjustable reset time of up to 20ms. The reset signal is low active, typically asserting low for 300ms after a reset trip condition has occurred.

In terms of applications, the MXD1813UR46+T can be used in a variety of electronic equipment, from industrial and medical instruments, to consumer electronic applications such as cell phones, tablets and even laptops. In particular, it can be used in applications that require high levels of precision monitoring and control such as power supplies, battery management, motor control systems, microcontrollers, and other embedded system applications.

The main working principle of the MXD1813UR46+T is to monitor the supply voltage within a range of 2.9V to 5.5V, providing power-on reset, monitoring supply voltage accuracy, and providing status flag presentation. If the voltage remains over or under the specified range, the device will initiate a reset signal. Moreover, the device also provides over temperature protection, over current protection, and under voltage protection.

Overall, the MXD1813UR46+T is a low power PMIC – Supervisors IC and has a variety of applications in industrial, medical and consumer electronic devices. It provides true voltage monitoring and has three phases of protection for over temperature, over current, and over voltage. The integrated protection circuit also provides UVLO protection and a reset timer of up to 20ms. Moreover, the device supports very low standby currents and a Noise Immunity (NMI) input to reject signal noise pulses beyond 0.2V, providing stable operation for the device and the application.
