Overview
The LM5110-2SD is a dual-channel MOSFET gate driver manufactured by Texas Instruments. It provides independent high-side and low-side outputs with peak drive currents of 5A and 3A respectively. The device operates within a supply voltage range of 3.5V to 14V and features an inverting logic configuration. Key timing parameters include a rise time of 14ns and a fall time of 12ns. It is housed in a compact WSON-10 package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Dual independent channel architecture supporting separate high-side and low-side control
- Integrated negative output voltage capability for enhanced driving performance
- Compact surface-mount packaging designed for space-constrained applications
Applications
- Synchronous buck converter power stages
- Half-bridge and full-bridge DC-DC converter topologies
- Motor driver circuits requiring precise switching control
Procurement Notes
Verify the specific suffix designation against official documentation, as variations such as NOPB indicate lead-free status. Confirm that the requested part number matches the exact pinout and electrical specifications required for your circuit design. Ensure compatibility with your manufacturing processes regarding the WSON-10 package type.
Selection Notes
Select this component when independent control of two switches is required within a single package. Consider the 5A/3A current asymmetry if asymmetric switching speeds are beneficial. Evaluate the 14V maximum supply limit against your bus voltage requirements. The inverting logic configuration must align with your controller's output polarity.
Part Context
This device belongs to the LM5110 series of compound gate drivers. It is functionally related to variants like the LM5110-3SD/NOPB, which share similar dual-channel capabilities but may differ in specific package markings or secondary ordering suffixes. The series targets efficient power management solutions.
Replacement Considerations
Public confirmed substitute part numbers include LM5110-3SD/NOPB and LM5110-3SDX/NOPB. These alternatives offer identical functional characteristics and should be verified for pin-to-pin compatibility before implementation.
