MPQ18021HS-A-LF-P

Overview

The MPQ18021HS-A-LF-P is a high-frequency half-bridge gate driver designed for N-channel power MOSFETs. It features a supply voltage range of 9 V to 18 V and delivers an output current of 2.5 A. The device exhibits a typical propagation delay of 16 ns with matched rise and fall times of 12 ns and 9 ns, respectively. It operates within a temperature range of -40 °C to +125 °C and is housed in an SOIC-8 package.

Feature Summary

• High-frequency half-bridge configuration for independent control of upper and lower N-channel MOSFETs
• Integrated bootstrap diode reduces external component count
• TTL-compatible input logic levels
• Under-voltage lockout protection for both high-side and low-side drivers

Applications

• Motor drive systems
• Industrial inverters
• Power supply circuits requiring isolated or floating gate driving

Procurement Notes

Verify the specific suffix 'HS' against official Monolithic Power Systems documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and package type for your PCB layout. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement.

Selection Notes

Select this component when driving N-channel MOSFETs in half-bridge topologies requiring fast switching speeds. The 2.5 A peak output current supports moderate gate charge loads. Consider the integrated bootstrap diode for simplified circuit design. Verify that the input signal timing aligns with the 16 ns propagation delay specifications to prevent shoot-through conditions.

Part Context

This part belongs to the MP18021 family of high-voltage gate drivers from Monolithic Power Systems. The MPQ series designation typically indicates automotive-grade qualification or enhanced reliability standards compared to standard industrial variants. It serves as a specialized interface between low-power control logic and high-power switching elements.

Replacement Considerations

MP18021HN-LF-P: Industrial grade equivalent with similar electrical characteristics but potentially different qualification standards. MP1921HS-A-LF-P: Alternative MPS half-bridge driver with identical pinout and performance metrics.
