Detailed Pin Configuration

The TPS2041BDGN features an 8-pin MSOP package with the following pin configuration:

1. EN (Enable): Controls the operation of the device.
2. GND (Ground): Connected to the ground reference of the system.
3. IN (Input): Receives the power supply input.
4. OUT (Output): Provides the regulated power output.
5. OC (Overcurrent): Detects overcurrent conditions.
6. OV (Overvoltage): Detects overvoltage conditions.
7. FLT (Fault): Indicates the occurrence of a fault condition.
8. PG (Power Good): Signals the availability of regulated power output.

Functional Features

• Overcurrent Protection: The TPS2041BDGN monitors the current flowing through the load and quickly shuts off the power supply if an overcurrent condition is detected.
• Overvoltage Protection: It also safeguards against excessive voltage levels by disconnecting the load when an overvoltage condition occurs.
• Fast Response Time: With a response time of less than 1µs, the TPS2041BDGN provides rapid protection to prevent damage to sensitive components.
• Adjustable Thresholds: The overcurrent and overvoltage thresholds can be adjusted to suit specific application requirements.
• Fault Indication: The FLT pin signals the occurrence of a fault condition, allowing for easy troubleshooting and system diagnosis.
• Power Good Signal: The PG pin provides a reliable indication of the availability of regulated power output, ensuring proper functioning of downstream components.

Advantages and Disadvantages

Advantages

• Efficient power distribution and protection
• Fast response time prevents component damage
• Adjustable thresholds for customization
• Compact package size allows for flexible integration
• Low power consumption enhances overall system efficiency

Disadvantages

• Limited to a specific range of input voltages (2.7V to 5.5V)
• Requires additional external components for complete power management solution

Working Principles

The TPS2041BDGN operates based on a combination of current sensing and voltage monitoring techniques. It continuously monitors the current flowing through the load and compares it with the user-adjustable overcurrent threshold. If the current exceeds this threshold, the device quickly shuts off the power supply to protect the load.

Similarly, the TPS2041BDGN also monitors the voltage across the load and compares it with the user-adjustable overvoltage threshold. If the voltage surpasses this threshold, the device disconnects the load to prevent any damage.

The fast response time of the TPS2041BDGN ensures that protection is provided almost instantaneously, minimizing the risk of component failure.

Detailed Application Field Plans

The TPS2041BDGN finds applications in various fields where power distribution and protection are critical. Some of the detailed application field plans include:

1. Consumer Electronics: Used in smartphones, tablets, laptops, and other portable devices to safeguard sensitive components from overcurrent and overvoltage conditions.
2. Industrial Automation: Integrated into control systems, PLCs (Programmable Logic Controllers), and motor drives to ensure reliable power supply and protect against faults.
3. Automotive Electronics: Employed in automotive systems such as infotainment units, engine control modules, and lighting systems to enhance safety and prevent damage due to power fluctuations. 4
