Overview
The DRV8350RSRGZR is a three-phase smart gate driver manufactured by Texas Instruments, designed for brushless DC motor applications. It operates within a supply voltage range of 6 V to 95 V and supports load voltages from 9 V to 75 V. The device features an integrated buck regulator capable of delivering up to 2 A to power external components. It includes three high-side and three low-side gate drivers with peak output currents of 25 mA. Communication is handled via an SPI interface, allowing for configuration and monitoring. The unit is housed in a 48-VQFN package and functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrates a buck converter for efficient power management of external circuitry
- Provides hardware-based protection mechanisms including over-current and thermal shutdown
- Supports digital control through a serial peripheral interface for flexible system integration
Applications
- Brushless DC motor drives
- Industrial automation systems
- Home appliance motor control
Procurement Notes
Verify the specific suffix RSRGZR to confirm the reel packaging format and pinout compatibility. Ensure the design accounts for the moisture sensitivity level indicated in the datasheet. Confirm that the host microcontroller supports the required SPI communication protocol. Check for any regional compliance requirements such as RoHS status before finalizing procurement.
Selection Notes
Select this component when a compact solution for three-phase BLDC motors is required. It is suitable for designs needing integrated gate driving and current sensing capabilities without external discrete drivers. Consider the 48-VQFN package size constraints and thermal dissipation requirements. Verify that the input voltage range matches the system power supply specifications.
Part Context
This part belongs to the DRV8350R series of smart gate drivers from Texas Instruments. It is engineered to simplify the design of three-phase motor control systems by integrating essential drive and protection functions. The series is commonly used in applications requiring reliable motor operation with minimal external component count.
Replacement Considerations
The DRV8350RSRGZT is a tape-and-reel alternative within the same family. The DRV8353RSRGZR offers similar functionality but may include additional features such as integrated current shunt amplifiers. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
