ON Semiconductor MC33164D-5R2 Voltage Supervisor IC
The MC33164D-5R2 is a precision undervoltage sensing integrated circuit (IC) designed by ON Semiconductor, a trusted leader in the semiconductor industry. This specialized chip is engineered to protect against low voltage conditions, ensuring that electronic systems operate within their intended voltage thresholds. It is ideal for use in a variety of applications where voltage supervision is critical, such as automotive systems, industrial controls, and battery-operated devices.
The device features a fixed-sense threshold voltage set at 5.0V, which makes it suitable for monitoring 5V power supplies and systems. When the input voltage drops below this threshold, the MC33164D-5R2 responds quickly by asserting a reset signal, thus safeguarding the system from operating under potentially damaging conditions. The reset signal remains active until the voltage recovers to an acceptable level, ensuring the system has stabilized before normal operation resumes.
With its low supply current draw, the MC33164D-5R2 is an energy-efficient solution that won't significantly impact the power budget of the system it's protecting. This characteristic is especially beneficial for battery-powered applications where power conservation is paramount.
The MC33164D-5R2 comes in a compact SOIC-8 package, making it easy to integrate into space-constrained designs. Its surface-mount form factor aligns with modern PCB assembly processes, facilitating streamlined manufacturing and reduced assembly costs.
Key features of the MC33164D-5R2 include:
- Fixed voltage threshold preset at 5.0V for straightforward implementation
