The KIA7039AF-RTF is a voltage detector manufactured by KEC (Korea Electronics Co., Ltd.). Voltage detectors, also known as voltage supervisors or reset ICs, are integrated circuits designed to monitor the voltage level of a power supply and generate a reset signal when the voltage falls below a certain threshold. This reset signal is used to prevent microcontrollers or other digital circuits from operating incorrectly due to insufficient voltage.

Applications:

• Microcontroller reset circuits
• Power supply monitoring
• Battery-powered devices
• Embedded systems
• Automotive electronics
• Industrial control systems

Features:

• Precise voltage detection threshold
• Open-drain output
• Low quiescent current
• Small package size
• RoHS compliant

Benefits:

• Reliable system reset: Ensures a proper system reset when the supply voltage drops below a safe operating level.
• Prevents data corruption: Protects data from being corrupted due to voltage fluctuations.
• Low power consumption: Minimizes power consumption in battery-powered applications.
• Compact size: Saves valuable board space in densely populated circuits.

Specifications:

The KIA7039AF-RTF voltage detection threshold is 3.9V. It consumes low quiescent current, extending battery life in portable applications. It features an open-drain output, requiring an external pull-up resistor. Datasheet specifications confirm this. Exact values for voltage threshold accuracy, quiescent current, output voltage levels, and operating temperature range must be confirmed in the official product datasheet from KEC.

The KIA7039AF-RTF provides monitoring for electronic systems.
