Overview
The DRV8353RHRGZT is a three-phase smart gate driver manufactured by Texas Instruments, designed for brushless DC motor applications. It integrates a buck regulator and three current shunt amplifiers within a 48-VQFN package. The device supports a supply voltage range of 6 V to 95 V, with an absolute maximum rating of 102 V. It features a 25 mA output current capability and operates at frequencies up to 200 kHz. The component functions across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a buck step-down converter for internal power management
- Includes three high-precision current shunt amplifiers for sensor-based control
- Supports hardware management interfaces alongside SPI/I2C communication protocols
- Provides smart gate drive capabilities for efficient half-bridge switching
Applications
- Brushless DC (BLDC) motor drives
- Field-oriented control (FOC) systems
- Sine wave current control applications
- Trapezoidal current control implementations
Procurement Notes
Verify the specific suffix RHRGZT against official datasheets to confirm the inclusion of integrated current shunt amplifiers and the buck regulator variant. Ensure compatibility with the 48-VQFN footprint and check moisture sensitivity levels for proper handling during assembly processes.
Selection Notes
Select this component when designing three-phase motor drives requiring integrated current sensing and voltage regulation. It is suitable for applications needing SPI or I2C interface control combined with hardware management signals. Consider the thermal performance of the VQFN package for high-temperature environments.
Part Context
This part belongs to the DRV8353R series of smart gate drivers from Texas Instruments. The series is engineered for high-performance BLDC motor control, offering integration of gate driving, regulation, and sensing functions to reduce external component count and board space in motor drive designs.
Replacement Considerations
The DRV8353RSRGZT is a documented substitute within the same family, differing primarily in the absence of integrated current shunt amplifiers.
