PMIC (power management integrated circuit) has been widely used in various electronic devices, from smart phones and computers to industrial control systems. One of the most widespread applications of PMICs is the MAX14690DEWX+T, a specialized power management integrated circuit for applications in industrial environments. This article will discuss the application field and working principle of MAX14690DEWX+T.

The MAX14690DEWX+T is a dedicated PMIC that integrates power electronics technologies and monitoring features that provide the optimal power supply solution for industrial applications. It has been specially designed for temperature-controlled applications in industrial automation, building automation, medical equipment and consumer devices. The PMIC features an integrated voltage regulator, an embedded temperature sensor and a protection circuit. It provides a single-power supply solution that operates in a wide temperature range of -25°C to +60°C.

The MAX14690DEWX+T offers a broad range of features for industrial power management. It is designed for input voltages from 4.5V to 20V, and provides a regulated output voltage of 5V. The PMIC also supports three power-saving modes including Standby, Sleep and Shutdown. Standby mode maintains a minimum supply current of 1µA and Sleep mode reduces the supply current to 3µA, and Shutdown mode reduces the current to 0.01µA. The PMIC also offers advanced power and protection features such as transient protection, over-voltage and over-current protection and reverse current protection.

The MAX14690DEWX+T is also built with an embedded temperature sensor. This enables the PMIC to monitor and regulate the temperature of the device, ensuring proper functionality in temperatures ranging from -25°C to +60°C. The PMIC also provides a temperature-controlled reset feature, which enables the device to accurately monitor and reset itself when the temperature exceeds a certain level.

In terms of working principle, the MAX14690DEWX+T utilizes switching regulators to convert voltage and current between input and output. It employs certain transistors and other components to direct the flow of the current and the voltage from the input source to the output device. The switching regulators use pulse-width modulation (PWM) to control the output voltage. The PMIC also utilizes a feedback loop to maintain a stable, consistent output voltage.

The MAX14690DEWX+T also offers comprehensive protection features for industrial applications. It employs a protection circuit that activates in case of an overheat, over-voltage, over-current, or reverse current situation. This ensures that the device is protected from unsafe operating conditions.

The MAX14690DEWX+T is an ideal PMIC for industrial power management applications. It offers a broad range of features and capabilities that make it an ideal solution for power management in temperature-controlled applications. It provides a high level of protection and superior temperature control, making it an ideal choice for temperature-sensitive applications. Additionally, the PMIC is highly reliable and provides a stable and consistent output voltage, making it a great choice for industrial applications.
