It is a Low-Threshold voltage supervisor IC specialized in System Reset Generation, mainly used in Insufficient Power Detection, and improving safety performance in industrial and automotive electronic product applications. It can maximize the safety performance, reduce the risk of unexpected application reset and corruption of system data.

Applications

The TPS3305-18DG4 is mainly used in industrial and automotive electronic product applications, including:

• Computer (Laptop/Desktop)
• Mobile phones, tablets and other portable devices
• Industrial Automation
• Communication Network
• Automotive Applications
• Consumer Electronics
• Solar Energy System

Working Principle

First of all, it monitors the input voltage and provide warning signals as feedback. It is generally implemented with a threshold voltage of 2.5V and work voltage of 2.6V. When the input voltage reaches the low threshold voltage, the reset output of TPS3305-18DG4 supervisor IC is changed from high level to low level, which triggers the reset signal. This will send out the warning signals in response to the low input voltage.

Apart from providing warning signals, the TPS3305-18DG4 supervisor IC also generates reset signals when the voltage drops below the low threshold voltage. The reset will happen when the power input drops or when the system restarts. This will help prevent the loss of important data or system failure.
