TPS2041BDRG4 Typical application Circuitry

TPS2041BDRG4

The TPS2041BDRG4 is a single-channel, current-limited, power distribution switch. TPS2041BDRG4 It's primarily designed for USB power distribution applications where protection and distribution of power are necessary. This chip is ideal for managing USB power requirements, particularly in preventing overcurrent situations.

Application Scenarios

1. USB Hubs: In USB hubs, it manages power distribution to each USB port, ensuring stable operation of connected devices.

2. Portable Charging Stations: Used in portable chargers to regulate and distribute power to multiple devices safely.

Key Parameters and Characteristics

- Current-Limited Power Distribution: Protects against overcurrent conditions.

- Single USB Channel Support: Designed for managing power in a single USB port.

- Thermal Shutdown Protection: Prevents overheating by shutting down the power switch if the temperature exceeds a safe limit.

- Fault Reporting: Includes a fault status output to indicate overcurrent or thermal shutdown conditions.

- Wide Operating Voltage Range: Suitable for various USB power supply standards.

- Low On-Resistance: Minimizes voltage drop and power loss across the switch.

- Automatic Retry Feature: After a fault condition, it automatically attempts to restart.

- Compact SOIC-8 Package: Ideal for space-constrained applications like USB hubs.

Detailed Circuit Connection for USB Hubs

1. Power Input (VIN Pin): Connect to the hub's main power supply, usually 5V for standard USB applications.

2. Power Output (VOUT Pin): Link this pin to the TPS2041BDRG4 USB port's power line for delivering controlled power to the connected device.

3. Ground Connection (GND Pin): Attach to the TPS2041BDRG4 hub's ground plane for circuit stability and reference.

4. Enable Input (EN Pin): Interface this pin with a control signal, typically from the hub's microcontroller, to turn the power switch on or off.

5. Overcurrent and Thermal Fault (FAULT Pin): Connect to an input on the hub's controller to report fault conditions.

6. Current Limit Set (ILIM Pin): Attach a resistor to this pin to set the desired current limit threshold.

7. Bypass Capacitor (Across VIN and GND): Place a bypass capacitor to stabilize the input power supply and filter noise.

8. Thermal Management (Exposed Pad): Ensure proper heat dissipation by connecting the exposed pad to the PCB thermal plane.

Design Considerations

- Stable Power Supply: Essential for reliable operation and consistent power distribution.

- Overcurrent Protection Setting: Accurately set the current limit for safe operation of connected devices.

- Thermal Handling: Adequate cooling, especially when multiple USB ports are in use.

- Fault Handling Mechanism: Effective management of fault conditions to protect both the hub and connected devices.

- Signal Integrity for Enable Line: Ensuring minimal interference on the enable control signal.

- Noise Minimization: Critical in maintaining USB data integrity.

- Compact Design Integration: Efficiently fitting the chip into the limited space of USB hubs.

- Automatic Retry Implementation: Configuring the chip to handle fault conditions with minimal user intervention.

Integrating the TPS2041BDRG4 into a USB hub requires careful consideration of these factors. Its role as a power distribution switch is crucial in USB applications, where managing power delivery and protecting against overcurrent conditions are essential for the stability and safety of the devices connected.
