常見問題解答
What is LM5104MX/NOPB?
The LM5104MX/NOPB is a high-voltage, half-bridge gate driver IC designed by Texas Instruments. It is specifically designed for driving both the high-side and low-side N-channel power MOSFETs in high-voltage switching applications such as motor drives, power supplies, and DC-DC converters.
How Does LM5104MX/NOPB Work?
The LM5104MX/NOPB works by providing the necessary drive voltage and current to the high-side and low-side MOSFETs in a half-bridge configuration. It utilizes a bootstrap technique to provide the high-side gate drive voltage above the input supply voltage. The device features adaptive shoot-thru protection and an integrated high-side diode to ensure robust and efficient operation.
How Many Pins does LM5104MX/NOPB have and What are the Functions of the Pinout Configuration?
The LM5104MX/NOPB is housed in a 10-lead WSON (Wide small-outline no-lead) package. The pinout configuration includes:
- VDD: Power supply for the high-side gate driver.
- HO: High-side gate driver output.
- VSS: Ground for the high-side gate driver.
- LI: Low-side gate driver input.
- VB: Bootstrap supply pin.
- HO_B: Bootstrap node for the high-side driver.
- VDD: Power supply for the low-side gate driver.
- HVB: High-voltage bias supply for the bootstrap diode.
- HO_B: Bootstrap node for the low-side driver.
- LO_B: Low-voltage bias supply for the bootstrap diode.
What are the Pros and Cons of LM5104MX/NOPB?
Pros:
- High Voltage Operation: Suitable for high-voltage applications up to several hundred volts.
- Adaptive Shoot-Thru Protection: Ensures robust and safe operation of the half-bridge driver.
- Bootstrap Operation: Utilizes bootstrap technique for efficient high-side gate drive voltage generation.
- Integrated Bootstrap Diodes: Simplifies external components and reduces component count.
Cons:
- Complexity: May require careful attention to layout and thermal management due to high-voltage operation.
- External Components: Requires external components such as bootstrap capacitors and bootstrap diodes for proper operation.
Are There Any Equivalents/Alternatives to LM5104MX/NOPB for Recommendation?
Some equivalents to the LM5104MX/NOPB include the IR2104 from Infineon and the HIP2100 from Renesas. Alternatives to consider are the FAN7382 from Fairchild Semiconductor and the IRS21844S from International Rectifier.
