TPS2331IPWRG4

PMIC - Hot Swap Controllers

The TPS2331IPWRG4 is a hot swap controller that is specifically designed to be used in systems where there needs to be a power off detection and power on detection. It is an integrated power switch that is triggered by an external control signal. The controller includes an integrated n-channel power MOSFET that operates as a power switch and is capable of carrying up to 3A at 3.3V.

Application Field

The TPS2331IPWRG4 is usually used in consumer and industrial applications that require the ability to power down and control power connections. This can be useful for automated processes, or for ensuring that activation of equipment is properly triggered. Additionally, the controller can be used for powering off devices as well when needed, allowing for a safe system shutdown.

It is commonly used in applications that require remote control power management such as power supplies, cellular or wireless networks, or sensor modules. The remote control capability allows for easy controlling of the power switch, giving reliability and accuracy that other power switches cannot provide. In addition, the controller is also widely used in applications where the ability to monitor and control power is essential, making it a great choice for systems that require precision power control.

Working Principle

The TPS2331IPWRG4 works by detecting when the input voltage is within the operating range (2.5V to 3.3V). When the voltage drops below the operating range, the internal MOSFET is enabled, allowing power to flow through the MOSFET and to its output. When the voltage rises above the operating range, the MOSFET is disabled, which forces the power to be automatically disconnected.

In addition, the on/off control signal from the external input can force the MOSFET to turn on or off. This allows for the system to be powered or powered down as quickly as needed from a remote location. Additionally, the controller also has a “power good” output that indicates when the input voltage is in a safe range. This output can be used as a safety indicator for devices that require an accurate power input.

Conclusion

The TPS2331IPWRG4 is a hot swap controller that is specifically designed to be used in systems that require remote power management and monitoring. It is enabled and disabled by detecting when the input voltage is within a specified range and can be forced on and off using an on/off control signal from an external input. In addition, the controller also has a “power good” output that indicates when the input voltage is in a safe range. The TPS2331IPWRG4 is an ideal choice for applications that need precision power control and safety features.
