Product Overview: TPS3705-30DR by Texas Instruments

The TPS3705-30DR is a high-precision supply voltage supervisor designed by Texas Instruments to ensure reliable operation of microprocessors and other voltage-sensitive devices. This integrated circuit (IC) monitors the supply voltage of microprocessor (MPU) or digital systems and provides a reset signal to the host system when necessary to prevent system failure or malfunction.

With its wide supply voltage range and low supply current, the TPS3705-30DR is an excellent choice for battery-powered and portable applications. It features a fixed-sense threshold voltage of 3.0V, which is ideal for monitoring 3.3V supply voltages, ensuring that systems remain within operational voltage limits.

Key Features:

• Voltage Monitoring: The TPS3705-30DR offers precise voltage monitoring to prevent data corruption and system errors. The fixed threshold accuracy is typically ±1.5%, providing a reliable safeguard for sensitive electronics.
• Reset Time Delay: It includes an adjustable time delay for the reset signal, allowing designers to customize the reset de-assertion to match specific system requirements.
• Low Power Consumption: The device is optimized for low power consumption, drawing a quiescent current of typically 9µA, making it suitable for power-sensitive applications.
• Push-Pull Reset Output: The reset output configuration is push-pull, which provides a robust signal that can directly interface with other digital components without the need for external pull-up resistors.
• Wide Operating Temperature: The TPS3705-30DR operates over a broad temperature range of -40°C to +85°C, accommodating a variety of environments and application conditions.

Applications:

This voltage supervisor is versatile and can be used in a wide range of applications, including:

• Portable/Battery-Powered Equipment
• Microprocessor/Microcontroller Systems
• Industrial Controls
• Embedded Systems
• Notebook/Desktop Computers
