Essence

The essence of the TPS3780DDRYR lies in its ability to accurately monitor and protect against excessive current flow in electronic systems.

Packaging/Quantity

This product is typically packaged in reels, with 3000 units per reel.

Specifications

• Input Voltage Range: 2.7V to 18V
• Quiescent Current: 10µA (typical)
• Overcurrent Threshold Range: 50mA to 500mA
• Response Time: 5µs (typical)

Detailed Pin Configuration

The TPS3780DDRYR has three pins:

1. VCC: Power supply input pin.
2. OUT: Output pin that provides a logic-level signal indicating the status of the current being monitored.
3. GND: Ground reference pin.

Functional Features

• Accurate current monitoring: The TPS3780DDRYR provides precise measurement of current flowing through the load.
• Overcurrent protection: It can detect and respond quickly to excessive current, triggering appropriate actions to prevent damage to the system.
• Adjustable threshold: The overcurrent threshold can be adjusted to suit specific application requirements.
• Low power consumption: The low quiescent current ensures minimal power loss during normal operation.

Advantages and Disadvantages

Advantages

• High accuracy current sensing enables precise monitoring.
• Wide input voltage range allows for versatile application.
• Fast response time ensures prompt protection against overcurrent events.
• Adjustable threshold provides flexibility in different scenarios.
• Low quiescent current minimizes power consumption.

Disadvantages

• Limited maximum overcurrent threshold range (up to 500mA).
• SOT-23 package may not be suitable for all design requirements.

Working Principles

The TPS3780DDRYR utilizes a precision current-sensing resistor and an internal comparator to monitor the current flowing through the load. When the current exceeds the set threshold, the output pin switches to a logic-level high state, indicating an overcurrent condition.

Detailed Application Field Plans

The TPS3780DDRYR finds applications in various electronic systems where accurate current monitoring and protection are crucial. Some potential application fields include:

1. Power supplies: Ensuring safe operation by detecting and protecting against excessive current draw.
2. Motor control: Monitoring motor currents to prevent damage due to overload or short circuits.
3. Battery management systems: Safeguarding batteries from overcurrent conditions during charging or discharging.
4. Industrial automation: Protecting sensitive equipment from current surges and faults.
5. Automotive electronics: Monitoring current flow in automotive systems to prevent damage and ensure safety.

Detailed and Complete Alternative Models

1. TPS3700DDCR: Similar functionality with adjustable overcurrent threshold, but in a different package (SC-70).
2. INA199A2IDBVR: Current shunt monitor with programmable gain and voltage output, suitable for more complex current measurement applications.
3. ACS712ELCTR-05B-T: Hall effect-based current sensor with a linear analog output, ideal for low-power applications.
