Overview
The MP1924HR-LF-Z is a high-frequency, 100V half-bridge gate driver designed for N-channel power MOSFETs. It features independently controlled low-side and high-side channels with a peak output current of 4A. The device operates within a supply voltage range of 8V to 15V and supports logic input levels of 1V (VIL) and 2.4V (VIH). It functions reliably across an extended temperature range from -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it dissipates up to 1.3W of power.
Feature Summary
- Independent control of low-side and high-side driver channels
- High-frequency operation capability for efficient switching
- Robust 100V breakdown voltage rating for high-voltage applications
Applications
- Motor drive systems requiring precise half-bridge control
- Industrial motion control circuits
- Ignition system drivers
Procurement Notes
Verify the specific suffix 'HR' against the datasheet to confirm package type and thermal characteristics. Ensure compatibility with the target N-channel MOSFET gate requirements. Confirm RoHS compliance status if required by assembly specifications. Check humidity sensitivity level for storage and reflow profile adherence.
Selection Notes
Select this component when a 100V rating and 4A peak drive current are necessary for half-bridge topologies. The SOIC-8 package suits space-constrained PCB layouts. Verify that the operating frequency aligns with the driver's switching speed capabilities. Ensure the control logic voltage levels match the specified 1V/2.4V thresholds.
Part Context
This part belongs to the MP1924 series of half-bridge gate drivers from Monolithic Power Systems. It is categorized under Motor/Motion/Ignition Controllers & Drivers within the PMIC family. The HR suffix typically denotes a specific package variant or thermal performance tier within the standard MP1924 lineup.
Replacement Considerations
MP1924HS-LF-P is a documented alternative within the same series offering similar half-bridge functionality. Verify pinout compatibility and package dimensions before substitution. Ensure electrical parameters such as supply voltage and drive current meet application requirements.
