Overview
The LM5111-1MYX/NOPB is a single-channel low-side gate driver from Texas Instruments, packaged in an 8-pin MSOP PowerPAD. It delivers a peak output current of 5 A and operates within a supply voltage range of 3.5 V to 14 V. The device features an inverting logic configuration with rise and fall times of 14 ns and 12 ns, respectively. It supports N-channel MOSFETs and functions reliably across an extended temperature range of -40°C to +125°C.
Feature Summary
- Provides high peak drive current for efficient switching control
- Features compact surface-mount packaging with exposed thermal pad
- Supports standard inverting logic input signals
Applications
- Low-side switching in DC-DC converter topologies
- Gate driving for power MOSFETs in motor control circuits
- Isolated gate drive interfaces in power electronics systems
Procurement Notes
Verify the specific suffix '1' indicates a single-channel variant distinct from dual-channel models like the LM5111-2. Confirm the MSOP-8 package type matches the design footprint. Ensure the NOPB designation confirms lead-free compliance and RoHS status before finalizing procurement orders.
Selection Notes
Select this component when a single-channel driver with 5 A peak capability is required. It is suitable for applications needing fast switching speeds with minimal propagation delay. Consider the thermal performance of the PowerPAD package for high-current duty cycles compared to standard SOIC packages.
Part Context
This part belongs to the LM5111 series of compound gate drivers designed for robust power management applications. The series offers various channel configurations and package options to suit different board space and current requirements while maintaining consistent electrical performance characteristics.
