Functional Features

• Overvoltage Protection: The TPS24741RGET monitors the input voltage and triggers a fault condition if it exceeds the set threshold.
• Adjustable Threshold: The overvoltage threshold can be adjusted to suit specific system requirements.
• Fast Response Time: The PMIC quickly responds to overvoltage events, minimizing the risk of damage to downstream components.
• Power Good Indicator: The PG pin provides an indication of the system's power status.
• Fault Indicator: The FLT pin signals the occurrence of an overvoltage fault.

Advantages and Disadvantages

Advantages

• Effective protection against overvoltage events.
• Wide input voltage range allows for versatile application.
• Low quiescent current consumption minimizes power wastage.
• Compact package size facilitates space-constrained designs.
• Adjustable threshold provides flexibility.

Disadvantages

• Limited to overvoltage protection functionality.
• Not suitable for applications requiring undervoltage or other types of protection.

Working Principles

The TPS24741RGET operates by continuously monitoring the input voltage. If the voltage exceeds the programmed threshold, the device triggers a fault condition by pulling the FLT pin low. Simultaneously, the PG pin goes low to indicate a power failure. The PMIC remains in this state until the input voltage drops below the threshold, at which point normal operation resumes.

Detailed Application Field Plans

The TPS24741RGET finds application in various electronic systems that require robust overvoltage protection. Some potential fields of application include:

1. Industrial Control Systems: Protecting sensitive control circuitry from voltage transients.
2. Automotive Electronics: Safeguarding automotive ECUs and other critical components from voltage spikes.
3. Telecommunications Equipment: Preventing damage to telecom infrastructure due to power surges.
4. Consumer Electronics: Ensuring the longevity of consumer devices by mitigating overvoltage risks.
