L99H92QF-TR

Overview

The L99H92QF-TR is a half-bridge gate driver designed for automotive applications, manufactured by STMicroelectronics. It operates within a supply voltage range of 6 V to 28 V and supports a maximum operating temperature of +150 °C with a minimum of -40 °C. The device features two drivers and two outputs, delivering an output current of 70 mA. Key timing parameters include a rise time of 200 ns, a fall time of 200 ns, and a maximum propagation delay of 2 µs. It is qualified under AEC-Q100 standards and utilizes a QFN-32 package.

Feature Summary

• Automotive-grade qualification ensuring reliability in harsh environments
• High-temperature operation capability up to 150 °C
• Non-inverting configuration for straightforward control logic

Applications

• Automotive motor bridge driving
• General-purpose half-bridge gate driving
• Industrial motor control systems

Procurement Notes

Verify the specific suffix 'QF' against official documentation to confirm package type and automotive qualification status. Ensure compatibility with system voltage requirements between 6 V and 28 V. Confirm thermal management strategies are adequate for the QFN-32 package given the high-temperature operational limits. Cross-reference the AEC-Q100 certification details with project specifications.

Selection Notes

Select this component when a robust, automotive-certified half-bridge driver is required for high-temperature environments. The 70 mA output current suits moderate load driving needs. Consider the QFN-32 footprint for space-constrained designs. Verify that the non-inverting logic aligns with the control interface signals. Compare against similar models like the L99H02QFTR if different output currents or packages are needed.

Part Context

This part belongs to the L99H92 series of gate drivers from STMicroelectronics, specifically tailored for automotive power management and motor control applications. It falls under the broader category of PMIC and Gate Drivers, offering specialized solutions for bridging low-voltage control signals to high-power MOSFETs in demanding vehicular contexts.

Replacement Considerations

The L99H02QFTR is a documented alternative within the same manufacturer's portfolio, featuring similar automotive qualifications but differing in output current (38 mA vs. 70 mA) and package type (LQFP-32 vs. QFN-32). Verify pinout compatibility and electrical parameter differences before substitution.
