Overview
The MP18021HN-A-LF-Z is a high-frequency half-bridge gate driver manufactured by Monolithic Power Systems. It is designed to drive N-channel power MOSFETs in half-bridge configurations with a VBST voltage range of up to 100V. The device features independent control of high-side and low-side channels, with matched propagation delays less than 5ns. It includes an integrated bootstrap diode to minimize external component count. Typical switching times at 12V VDD driving a 1nF load are 12ns rise time and 9ns fall time. The supply voltage range is 9V to 16V, with static current below 150μA. It offers under-voltage lockout protection for both drivers and accepts TTL-compatible inputs.
Feature Summary
- Supports 100V high-side voltage range for driving N-channel MOSFETs
- Features matched propagation delays of less than 5ns for precise timing
- Integrates a bootstrap diode to reduce external bill of materials
- Provides under-voltage lockout protection for both high-side and low-side drivers
Applications
- High-frequency motor control systems
- Power supply inverters
- Industrial automation drives
- Battery management system switches
Procurement Notes
Verify the specific suffix 'A' against official MPS documentation to confirm pinout or electrical variations compared to standard variants like MP18021HN-LF-Z. Ensure the SOIC-8 EPAD package matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's declaration before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring high-speed switching with tight delay matching between half-bridge legs. The 100V rating suits applications driving medium-voltage MOSFETs. Consider the 9V-16V supply range for compatibility with standard logic levels. The integrated bootstrap diode simplifies layout compared to discrete solutions.
Part Context
This part belongs to the MP18021 series of half-bridge gate drivers from Monolithic Power Systems. The series is characterized by high-frequency operation and robust protection features. Variants within the family may differ in package types, such as QFN-8 or SOIC-8, but share core functional specifications for driving N-channel power devices.
