The TPS3707-33DRG4 is a high-precision supply voltage supervisor designed and manufactured by Texas Instruments. This device is engineered to provide reliable monitoring of system voltages, ensuring that microprocessors (µPs), microcontrollers (MCUs), and other voltage-sensitive components operate within their specified voltage ranges.

Key Features

• Voltage Monitoring: This supervisor monitors a fixed 3.3V supply voltage with a tight accuracy of 2.5%, which is crucial for systems that demand consistent and precise voltage regulation.
• Reset Time Delay: It offers an adjustable delay time after voltage detection, which can be set by an external capacitor, ensuring that the system has adequate time to stabilize before it is allowed to resume operation.
• Low Power Consumption: Designed for power-sensitive applications, the TPS3707-33DRG4 consumes a very low quiescent current, making it suitable for battery-powered and energy-efficient systems.
• Supply Voltage Range: The device supports a wide supply voltage range, accommodating various application requirements and enhancing its versatility in different system configurations.
• Reset Output: It features an active-low RESET output, which can directly interface with the reset or enable the line of processors and other ICs, providing a clear and reliable signal to indicate when the voltage is out of the specified range.

Applications

The TPS3707-33DRG4 is ideal for a broad range of applications, including:

• Portable and battery-powered equipment
• Industrial controls
• Embedded systems
• Networking equipment
• Medical devices

Package and Quality

This voltage supervisor comes in a small-outline integrated circuit (SOIC) package, which is suitable for surface-mount technology (SMT) and occupies minimal space on a printed circuit board (PCB). Texas Instruments is known for its commitment to quality, and the TPS3707-33DRG4 is no exception, meeting stringent industry standards for performance and reliability.
