The TPS3103E15DBVTG4 is a highly reliable, low-power supervisory circuit designed by Texas Instruments to monitor power supplies in digital systems. It provides essential functions such as power-on reset control, watchdog timer, and manual reset in a single chip, ensuring that microprocessors and other digital systems can operate reliably under variable conditions and during power-up/down scenarios.

Key Features

• Power Supply Voltage Monitoring: The device supports a fixed-sense threshold voltage of 1.5V, which is ideal for monitoring low-voltage supply rails.
• Watchdog Timer: An integrated watchdog timer ensures that the system will reset if the software becomes unresponsive or deviates from its expected operation.
• Manual Reset Input: This input allows for a manual system reset, enabling greater control over the system's operation and recovery.
• Supply Current: Ultra-low supply current of 9μA (typical) makes the TPS3103E15DBVTG4 suitable for battery-powered and power-conscious applications.
• Reset Time Delay: The device features a programmable delay time for the reset signal, allowing designers to tailor the reset timing to specific system requirements.
• Temperature Range: The device operates over a temperature range of -40°C to 85°C, accommodating a wide range of environmental conditions.
• Packaging: Available in a small 6-pin SOT-23 package, the TPS3103E15DBVTG4 is designed for space-constrained applications.
