The X5329V14 is a versatile and feature-rich power management IC (PMIC) that is specifically designed to meet the increasing needs of space-constrained and cost-driven applications. It provides a total current management operation from primary power sources to the system’s power rails. It is also an ideal choice for use in portable electronic devices that require a low standby current. It is also suitable in a variety of other applications such as automotive, appliance and security applications. The X5329V14 provides a complete solution for applications needing high accuracy and performance, including low current monitoring and even deep sleep modes.

The X5329V14 is classified as a supervisor, or supervisors-on-a-chip (SOC), which is a power management integrated circuit (PMIC) that includes a range of specialized control functions. Supervisors can help reduce system design complexity and cost by combining power management and control functions into a single device. The X5329V14 includes a range of features that are commonly used in supervisors, such as under voltage detection, over voltage detection, and overtemperature detection.

The X5329V14 provides an efficient and accurate voltage monitoring and detection capability, with a low history of false trip points and a wide selection of operating input and output thresholds. It offers an adjustable transformer-rated load disconnect circuit and a power on reset option with manual reset input and a monotonic start-up circuit. The X5329V14 is designed to sense multiple power rails and provide indication of their status and accuracy, as well as providing detailed information on the last power-on reset. Detailed status of the device can be monitored through the I2C or SPI interface.

At the heart of the X5329V14 PMIC is a voltage control unit (VCU) that is responsible for controlling the device’s input and output voltages. The VCU is implemented using a mixed signal circuit design, which combines analog and digital circuits for improved accuracy and performance. The voltage control loop of the VCU is based on a sensing mechanism, incorporating a voltage regulator, voltage reference and a voltage feedback system. The VCU also incorporates current monitoring and primary-rail switch control functions.

The X5329V14 provides a wide range of overvoltage, undervoltage and overtemperature protection features, as well as load-disconnect and power-on reset control. When operating within its optimum voltage and thermal conditions, the X5329V14 can serve as an excellent supervisor to monitor and control input and output voltages on multiple rails, ensuring secure operation in extreme environments. The X5329V14 is a versatile and reliable solution for powering and controlling the primary power sources of a variety of applications, providing superior performance and power management.
