Overview
The DRV8350HRTVT is a three-phase smart gate driver manufactured by Texas Instruments, designed for brushless DC motor control applications. It operates within a supply voltage range of 6 V to 95 V and supports load voltages up to 75 V. The device features an output current capability of 25 mA per channel and maintains a quiescent supply current of 8.5 mA. It functions at a switching frequency of 200 kHz and is housed in a 32-WQFN package with dimensions of 5x5 mm. The component is rated for operation between -40°C and +125°C ambient temperature.
Feature Summary
- Integrates high-side and low-side gate drivers for three-phase BLDC motor commutation
- Supports SPI interface for configuration and status monitoring
- Includes built-in protection mechanisms against over-current and thermal events
Applications
- Brushless DC (BLDC) motor drives
- Industrial automation systems
- Home appliance motor control
Procurement Notes
Verify the specific suffix 'H' indicates the functional safety or hardware variant requirements compared to standard versions. Confirm the WQFN-32 package compatibility with your PCB footprint. Ensure ESD precautions are observed during handling due to moisture sensitivity classification. Cross-reference the datasheet revision date to ensure alignment with your design specifications.
Selection Notes
Select this component when a compact solution for three-phase motor control is required with integrated gate driving capabilities. The 25 mA output current suits moderate power MOSFETs. Consider the 6 V to 95 V input range for flexibility in various bus voltage architectures. The 32-pin QFN package offers a small form factor suitable for space-constrained designs.
Part Context
This part belongs to the DRV8350 family of smart gate drivers from Texas Instruments. It is distinct from the DRV8353 series which may include additional analog front-end features. The 'H' suffix typically denotes specific hardware or functional variations within the product line. It serves as a core driver IC for multi-phase motor applications requiring efficient power management.
Replacement Considerations
The DRV8350SRTVT is listed as a parameter-equivalent alternative within the same family. Verify pinout and electrical specifications before substitution. Other variants like DRV8350FHRTVR offer functional safety certifications.
