Q & A
- What is the input voltage range of the TPS2041CDBVR?
The input voltage range is 2.7V to 5.5V.
- What is the maximum continuous output current of the TPS2041CDBVR?
The maximum continuous output current is 500 mA.
- What is the typical on-state resistance of the TPS2041CDBVR at 5V and 25°C?
The typical on-state resistance is 95 mΩ.
- Does the TPS2041CDBVR have thermal protection?
Yes, it includes thermal protection to prevent device damage during heavy-overload or short-circuit faults.
- How does the enable input work on the TPS2041CDBVR?
The enable input is active-low, meaning the switch is enabled when the input is low and disabled when the input is high.
- What is the purpose of the overcurrent (OC) output on the TPS2041CDBVR?
The OC output is asserted (active low) when an overcurrent or overtemperature condition is encountered and remains asserted until the condition is removed.
- Can the TPS2041CDBVR handle hot-plug events?
Yes, it is designed to handle hot-plug events and can manage inrush current effectively.
- What is the operating junction temperature range of the TPS2041CDBVR?
The operating junction temperature range is -40°C to 125°C.
- How does the current sense and limiting feature work on the TPS2041CDBVR?
The current sense feature uses a sense FET to monitor the current and limits it during overload or short-circuit conditions, switching the device into constant-current mode if necessary.
- Is the TPS2041CDBVR compatible with both TTL and CMOS logic levels?
Yes, the enable input is compatible with both TTL and CMOS logic levels.
