TPS3823A-33DBVT

PMIC - Supervisors

As with most PMIC supervisors, the Texas Instruments TPS3823A-33DBVT provides a current trip point that monitors the main power supply rail to detect an over-current condition. When an over-current condition is detected, the device will shut off the main power supply and it will remain off until a manual reset is performed. The device also features adjustable voltage and current thresholds, so it can be tweaked to match the specific power requirements of different designs. The TPS3823A-33DBVT can also be used to monitor other rail voltages, such as the battery voltage.

The TPS3823A-33DBVT is designed to be used in applications such as laptops and PCs, as well as other devices that require power management solutions. It is also used in embedded systems, such as MCUs and ASICs. The device has a wide input voltage range of 4.5V to 28V and operates from a temperature range of -40°C to 125°C.

Working Principle

The TPS3823A-33DBVT works on the principle of current trip point monitoring. When an over-current condition is detected, the device will shut off the main power supply and it will remain off until a manual reset is performed. The device also features adjustable voltage and current thresholds, so it can be tweaked to match the specific power requirements of different designs.

The device has an adjustable factory-programmed current limit, which sets the level at which an over-current condition is detected. The device also has a selectable power-up delay, which allows for power-up sequencing and delayed turn-on for critical components. The device also has an optional over-voltage fault flag, which sets the voltage level at which an over-voltage condition is detected.

The TPS3823A-33DBVT also features an adjustable power-down delay and an open-drain signal output, which can be used to provide a warning signal in the event of an over-current condition. The device is also designed to be protected against over-temperature, over-voltage and reverse current conditions.

Benefits

The TPS3823A-33DBVT offers a wide range of benefits for applications which require power management solutions. It allows for flexibility of power-up sequencing and delay time for critical components, so users can ensure their designs are optimized for power efficiency. The adjustable current limit enables users to set different protection levels for their designs based on the specific power requirements of the device. The device also supports over-voltage and over-temperature protection, as well as reverse current protection, ensuring reliable operation.

The device is also designed to be highly efficient, consuming only a fraction of the energy of other PMIC supervisors. The device also has a wide temperature range, which allows it to be used in a wide variety of applications. Finally, the device features an open-drain signal output, which can be used to provide a warning signal in the event of an over-current condition.

Conclusion

The Texas Instruments TPS3823A-33DBVT provides an excellent choice for applications, which require reliable power management solutions. The device offers adjustable voltage and current thresholds, adjustable power-up and power-down delays and open-drain signal output, making it ideal for a wide range of applications. The device also offers protection against over-voltage, over-temperature and reverse current conditions, ensuring reliable operation in any environment. Finally, the device is highly efficient and consumes only a fraction of the energy of other PMIC supervisors.
