Overview
The MIC44F18YMME-TR is a high-speed, low-side MOSFET gate driver manufactured by Microchip Technology. It is designed to drive capacitive loads with peak output currents of 6A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 13.2V and features an enable input for power management. It is housed in an 8-pin MSOP package with an exposed pad for thermal dissipation. The component supports operating temperatures from -40°C to +125°C and includes internal shoot-through protection.
Feature Summary
- Provides high peak current capability of 6A for rapid switching of MOSFETs
- Includes an active-low enable pin for precise control and power saving
- Features internal shoot-through protection to prevent cross-conduction
- Operates over an extended industrial temperature range
Applications
- High-frequency DC-DC converters
- Motor control systems
- Power supply inverters
Procurement Notes
Verify the specific suffix 'YMME-TR' to confirm the MSOP-EP package and tape-and-reel packaging format. Ensure compatibility with the 4.5V to 13.2V supply range requirements of the target circuit. Confirm that the lead-free status aligns with assembly specifications. Cross-reference the manufacturer part number against the latest Microchip datasheet to ensure no design changes have occurred since the document publication date.
Selection Notes
Select this component when a single-channel, low-side driver with 6A peak current is required. It is suitable for applications needing fast switching speeds with minimal propagation delay. Consider the exposed pad thermal performance if high duty cycles are expected. Verify that the input logic levels match the controlling microcontroller or FPGA outputs.
Part Context
This part belongs to the MIC44F1x family of high-speed MOSFET drivers from Microchip (formerly Micrel). The family includes variants like MIC44F19 and MIC44F20, which offer similar performance characteristics but may differ in specific pinouts or additional features. These drivers are engineered for efficiency and reliability in power conversion applications.
Replacement Considerations
Direct substitutes include MIC44F18YMME without the reel suffix for sample testing. Check MIC44F19YMME-TR if inverted logic is acceptable. Verify pin-to-pin compatibility before replacing with other 6A low-side drivers from different manufacturers.
