The TPS2350DR, manufactured by Texas Instruments, is a robust, feature-rich power distribution switch designed for applications requiring circuit protection and power management. This integrated circuit (IC) is particularly suited for systems that need to control power distribution to various subsystems while providing a high level of protection and reliability. The TPS2350DR is commonly used in hot-swap and electronic circuit breaker applications.

Key Features

• Integrated MOSFET: The TPS2350DR includes an N-channel MOSFET that can handle continuous currents up to 2.7A, making it ideal for managing moderate power loads.
• Programmable Current Limit: Users can set the current limit threshold via an external resistor, allowing for precise control over the power delivered to connected devices.
• Fast Overcurrent Response: The device reacts quickly to overcurrent conditions, helping to protect the system and connected components from damage.
• Under-Voltage Lockout (UVLO): This feature ensures that the switch remains off if the input voltage is below a certain threshold, preventing malfunctioning due to insufficient supply voltage.
• Overvoltage Protection: The TPS2350DR is equipped with overvoltage protection to safeguard the system against voltage spikes and transients.
• Thermal Shutdown: The built-in thermal shutdown feature helps to prevent overheating, further enhancing the safety of the system.
• Status Flag: An open-drain power good output indicates whether the output voltage is within the normal operating range, providing real-time system monitoring.
