ON Semiconductor MC33164D-5 Voltage Supervisor IC

The MC33164D-5 is a precision voltage supervisor integrated circuit (IC) designed by ON Semiconductor, renowned for its high-quality electronic components. This compact and efficient IC is engineered to monitor the voltage level of power supplies or voltage references and ensure that the systems are functioning within their specified voltage ranges.

With its fast response time and low power consumption, the MC33164D-5 is an ideal solution for a variety of applications including microprocessor systems, digital systems, and portable battery-powered devices. Its primary function is to provide a reset signal to the host system whenever the monitored voltage drops below a predefined threshold, thereby protecting the system from unstable operation due to insufficient power.

The MC33164D-5 features a fixed voltage threshold of 4.55V, which is a common reset trigger level for 5V systems. It has an open-drain output configuration, which allows for flexibility in interfacing with different logic levels. The output remains asserted until the voltage rises back above the reset threshold plus a hysteresis margin, ensuring a clean reset signal without false triggering.

Constructed in a small-outline package, the MC33164D-5 is space-efficient and can be easily integrated into space-constrained applications. It is designed for a wide operating temperature range, making it suitable for industrial and automotive environments where temperature variations are a concern.

Key features of the MC33164D-5 include:

• Precision monitoring of 5V power supply voltages
• Fixed threshold voltage of 4.55V
• Open-drain output for easy interfacing
• Low power consumption for battery-powered applications
• Fast response time to ensure timely system protection
• Wide operating temperature range for reliability in varying conditions
• Compact SOIC-8 package for space-saving design

ON Semiconductor's commitment to quality ensures that the MC33164D-5 meets stringent reliability and performance standards. This voltage supervisor IC is a crucial component for maintaining the integrity of electronic systems and preventing damage caused by voltage anomalies.
