DRV8350FHRTVR

Overview

The DRV8350FHRTVR is a three-phase brushless DC motor controller and driver from the DRV8350F series, designed for functional safety 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 phase and maintains a quiescent supply current of 8.5 mA. It functions at a switching frequency of 200 kHz with an output voltage range of 2.5 V to 75 V. Housed in a WQFN-32 package, it withstands operating temperatures from -40°C to +125°C.

Feature Summary

• Integrated three-phase smart gate driver architecture optimized for BLDC motor control
• Functional safety qualification supporting high-reliability industrial and automotive environments
• Digital interface compatibility enabling precise configuration and monitoring via SPI

Applications

• Industrial automation systems requiring robust motor control
• Automotive powertrain and chassis subsystems
• High-efficiency brushless DC motor drives

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure the design accommodates the WQFN-32 package requirements for proper soldering and heat dissipation. Confirm that the system voltage does not exceed the 95 V absolute maximum rating. Check for moisture sensitivity level compliance during storage and handling procedures.

Selection Notes

Select this component when functional safety certification is mandatory for the application. Compare against standard DRV8350 variants if safety features are unnecessary. Evaluate the 25 mA output current against the target MOSFET gate charge requirements. Consider the WQFN-32 footprint constraints relative to available PCB space and thermal management capabilities.

Part Context

This part belongs to the DRV8350F family, which distinguishes itself through functional safety enhancements compared to the standard DRV8350 series. It serves as a specialized solution for critical motion control tasks where reliability and diagnostic integrity are prioritized over cost-sensitive general-purpose applications.

Replacement Considerations

The DRV8350SRTVR is a documented alternative within the same product family, offering similar electrical specifications but without the functional safety designation.
