ON Semiconductor MC33064D-5G Voltage Supervisor IC

The ON Semiconductor MC33064D-5G is a precision voltage supervisor integrated circuit (IC) designed to monitor voltage levels in a wide array of electronic applications. This device is particularly suited for use in power supply systems to control the power-on reset function, helping to ensure that microprocessors and other digital systems initialize correctly and operate safely.

The MC33064D-5G is part of the MC33064 series, which are undervoltage sensing circuits that trigger a reset if the input voltage drops below a precisely defined threshold. With a threshold voltage of 4.55 volts, this particular model is optimized for 5V systems. The device features a significant delay time, which is inherently programmed to be approximately 300ms, providing a stable reset signal without the need for external capacitors.

Key features of the MC33064D-5G include:

• Threshold Voltage: Precisely set at 4.55V for 5V systems.
• Operating Voltage Range: Designed to operate over a wide voltage range from 1V to 10V.
• Programmed Delay Time: Approximately 300ms delay to ensure system stability.
• Low Standby Current: Helps to conserve power in battery-operated devices.
• Temperature Range: Capable of operating across a wide temperature range, making it suitable for various environments.
• Packaging: Available in a small outline package (SOIC), specifically in an 8-pin configuration, making it easy to integrate into space-constrained designs.

The MC33064D-5G is commonly used in microprocessor-based systems, portable/battery-powered equipment, intelligent instruments, and critical microcontroller power monitoring. Its primary function is to monitor the system voltage and reset the system reliably when necessary, thereby preventing malfunction due to power dips or brownouts.

With its precise voltage monitoring capabilities and integrated delay, the MC33064D-5G ensures that systems remain within safe operating conditions, which is crucial for maintaining the integrity and reliability of electronic devices. The compact form factor and low power consumption make it an ideal choice for designers looking to add robust power management to their applications without compromising on space or energy efficiency.
