• Features built-in overtemperature protection (OTP) and VCC under-voltage lockout (UVLO) for system reliability.
• Provides low-power mode operation capabilities to optimize energy efficiency during idle states.

Full Half-Bridge (H Bridge) Drivers Applications

• Server and data center VRM designs requiring precise load-line regulation.
• Industrial motor control systems utilizing digital multi-phase controllers.
• High-density point-of-load conversion architectures.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'T' indicates reel packaging configuration. Confirm RoHS compliance status as exemptions may apply. Check current supply chain status due to potential end-of-life constraints. Ensure compatibility with associated digital PWM controllers like the ISL68/69xxx series before finalizing procurement specifications.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when designing systems requiring integrated current sensing without external DCR networks. Choose the B-suffix variant specifically for 5V-compatible tri-state PWM interfaces. Evaluate the 5x6 QFN package for thermal performance requirements in dense layouts. Ensure the controller interface matches the 5V logic level rather than the 3.3V option.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the ISL99380 series of Smart Power Stage modules. It is engineered to work seamlessly with Renesas digital multi-phase controllers. The series focuses on simplifying design by removing traditional DCR sensing components while maintaining high accuracy across line, load, and temperature variations.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

The ISL99380R5935 serves as a functional alternative but utilizes a 3.3V-compatible PWM input instead of the 5V interface found in the B-suffix version. Verify logic level compatibility before substitution. Other variants within the ISL99380 family may offer different packaging or pin configurations.
