X5329V14I

The X5329V14I is a P-Channel, high-side, adjustable-current supervisor IC. It acts as a voltage protector that activates and deactivates the primary power rail at specified undervoltage and overvoltage thresholds, respectively. The current-limited and thermal-protected switch makes it a suitable choice for various applications, including automotive, consumer electronics, industrial, and battery-powered devices.

The X5329V14I is built around a voltage-controlled supervisor that measures the voltage on the primary power rail and activates/deactivates the power rail when the respective thresholds are reached. The device can be configured to drive an external transistor that works as an active-high/active-low switch for the primary rail.

The X5329V14I is a versatile device that can be used in a variety of applications. In automotive applications, the X5329V14I can be used to regulate the ignition power supply, ensuring that the car starts up and runs smoothly. In consumer electronics, it can be used to regulate the power supply to the display and audio subsystems, which is essential for proper system operation. In industrial applications, the X5329V14I can be used to regulate the supply voltage to controlling circuitry, such as MCUs, FPGAs, sensors, etc., ensuring that the device is always powered in the proper range. Lastly, in battery-powered devices, the X5329V14I can be used to ensure that the proper voltage levels are maintained for charging, discharging, and power operations.

The X5329V14I is designed to maintain accuracy even under extreme temperature and pressure conditions. It offers a wide temperature range from –40° to +125°C, and over-temperature protection up to +150°C. The device is protected against overvoltage, short-circuit, and ESD events. Additionally, it features thermal and current shutdown protection.

The X5329V14I has a wide adjustable voltage range from 0.45V to 3.63V and can be configured for hysteresis of 0.14 V or 0.4V. The device also features an adjustable trip current (minimum 0.62mA, maximum 3.2mA) that can be adjusted using a single resistor. The internal active latch mechanism keeps the output low after the primary voltage has risen beyond the specified overvoltage threshold.

The X5329V14I provides a robust and reliable solution for protecting the primary power rail from undervoltage and overvoltage events. It is extremely versatile and can be used in a variety of applications, such as automotive, consumer electronics, industrial, and battery-powered devices. The device is designed to maintain accuracy even under extreme temperature and pressure conditions, and features over-temperature, short-circuit, and ESD protection.
