ISO5851QDWRQ1 Typical application Circuitry

ISO5851QDWRQ1

The ISO5851QDWRQ1 is an advanced reinforced isolated IGBT gate driver with a split output designed by Texas Instruments. This device is specifically developed for driving IGBTs in high-voltage switching applications.

Key Features of the ISO5851QDWRQ1:

1. Reinforced Isolation: The ISO5851QDWRQ1 offers reinforced isolation, making it suitable for high voltage systems where safety is a priority.

2. High Output Current: The driver supports high peak output current of ±2.5 A, thus efficiently driving IGBTs.

3. Desaturation Detection: The ISO5851QDWRQ1 has a built-in desaturation (DESAT) detection feature that protects the IGBT from potentially damaging over-current conditions.

4. Under-voltage Lock-out (UVLO) protection: Both IGBT-side and input-side UVLO protections are implemented to ensure safe operation.

5. Wide Temperature Range: The chip can operate within the temperature range from -40°C to +125°C, making it useful for various application environments.

Applications of ISO5851QDWRQ1:

The ISO5851QDWRQ1 finds use in multiple applications, such as electric vehicle systems, motor control, and power delivery systems, where high voltage isolation and IGBT control are necessary.

Sample Circuit Connection - Driving an IGBT :

Here's how you might connect the ISO5851QDWRQ1 to an IGBT in a high-voltage switching circuit:

- Pin 1 (VCC2): Connect this pin to a clean power supply (usually 15V) on the isolated side.

- Pin 2 (GND2): Connect this pin to the isolated ground.

- Pin 3 (OUT+): This pin needs to be linked to the IGBT's gate.

- Pin 4 (OUT-): Connect this pin to the emitter of the IGBT.

- Pin 5 (DESAT): Connect this pin to the collector of the IGBT through a DESAT detection circuit.

- Pin 6 (FLT/RESET): Connect this pin to a microcontroller to monitor the fault status and reset the fault latch.

- Pin 7 (GND1): Connect this pin to the non-isolated ground.

- Pin 8 (VCC1): This pin should be connected to a clean 3.3V or 5V power supply on the non-isolated side.

- Pin 9 (IN+): Attach this pin to the controller's PWM signal.

- Pin 10 (IN-): Connect this pin to the PWM signal return or ground.

Design Considerations:

1. Power Supply Decoupling: Proper decoupling of power supplies with suitable capacitors is crucial to reduce noise.

2. Isolation: The isolation requirements of your design should be thoroughly considered. The ISO5851QDWRQ1 provides reinforced isolation, which is suitable for high voltage applications.

3. Heat Management: As this is a high-current driver, proper heat management is important. Consider using a heatsink if necessary.

4. Protection Features: Take advantage of the integrated UVLO and DESAT detection features for enhanced system reliability.

In conclusion, the ISO5851QDWRQ1 is an advanced, robust, and versatile high-voltage IGBT driver, offering reinforced isolation and excellent protection features. For demanding applications in the industrial and automotive sectors, it is the finest choice as a result.
