This device is a low-voltage supervisor that has a wide operating voltage range, operates at extremely low current consumption, and provides a variety of features for monitoring and providing fault coverage for highly reliable power system design.The MC33164P-005 is especially useful in circuit designs with high-density logic and MCUs (Microcontrollers). With its low cost and high performance, it is ideal for applications like automotive battery monitors, high-reliability industrial controllers, PCs, and other embedded systems.

Features

The MC33164P-005 is a highly advanced system supervisor device. It has an extensive set of features that enable it to easily control power systems and provide high reliability in designs. These features include: -low-voltage cut-off detection - watchdog -supply voltage monitoring - open collector reset-power-on reset -system enable -brown-out protection -polarity inversion protection.The MC33164P-005 has a wide operating voltage range of 2.0 to 12.0 V, making it useful for a wide variety of applications. It is available in a variety of packages, including 8-pin PDIP, 8-pin SOIC, 8-pin SSOP, and 10-pin TSSOP.

Working Principle

The MC33164P-005 is a low-voltage supervisor device used to monitor and control power systems. It is designed to provide fault coverage for highly reliable power system designs.When enabled, the MC33164P-005 will monitor the system’s supply voltage and issue an alert if it falls below a pre-set threshold. If the supply voltage falls below the under-voltage lock out threshold, the MC33164P-005 will assert the reset signal to maintain system stability.Additionally, the MC33164P-005 can be configured to monitor a reference voltage and issue an alert if the actual supply voltage is lower than the reference voltage. This feature can be used in applications where the system needs to enter a safe state due to over voltage faults.The MC33164P-005 also has a watchdog timer that can be used to reset the system if it does not receive an input signal within the pre-set timeout period. This can help maintain system operation by resetting the system if its operation is interrupted by a power fault or other unexpected event.Finally, the MC33164P-005 can be used to trigger an open-collector reset signal if the detected supply voltage falls to or below the under-voltage lockout threshold. This is useful for applications that require the reset signal to be used for resetting the connected devices.

Conclusion

The MC33164P-005 is a highly advanced system supervisor device that is used to monitor, control, and provide fault coverage for highly reliable power systems. It has an extensive set of features, including low-voltage cut-off detection, watchdog timer, supply voltage monitoring, open collector reset, power-on reset, system enable, brown-out protection, and polarity inversion protection. Additionally, it has a wide operating voltage range of 2.0 to 12.0 V and is available in a variety of packages.
