Overview
The LM5110-2SD/NOPB is a dual-channel low-side MOSFET gate driver manufactured by Texas Instruments. It features two independent drivers with an output current capability of 5 A per channel. The device operates within a supply voltage range of 3.5 V to 14 V and utilizes a non-inverting logic configuration. Packaged in a 10-pin WSON format, it supports surface-mount installation. Key timing parameters include a rise time of 14 ns and a fall time of 12 ns. The component is rated for operation across a temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel architecture providing independent control for two low-side switches
- Non-inverting input logic simplifies interface with standard digital controllers
- Integrated negative voltage output capability supports bootstrap or auxiliary power applications
Applications
- Low-side switching in synchronous buck converters
- Gate driving for power MOSFETs in DC-DC conversion modules
- Control circuits in industrial power management systems
Procurement Notes
Verify the specific suffix '2SD' against the manufacturer's official datasheet to confirm the non-inverting configuration and pinout assignment. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the RoHS compliance status and lead times directly with authorized distributors to guarantee component authenticity and supply chain reliability before finalizing procurement.
Selection Notes
Select this component when a dual-channel low-side driver with moderate speed and high current drive is required. The non-inverting logic is suitable for direct interfacing with microcontrollers without additional inversion circuitry. Consider the 10-pin WSON package constraints for thermal performance and board space. Evaluate the 5 A peak current against the total gate charge of the target MOSFETs to ensure adequate switching performance within the specified operating temperature range.
Part Context
This device belongs to the LM5110 series of gate drivers designed for efficient power conversion. It complements other variants like the LM5110-1SD (inverting) and LM5110-3SD (non-inverting) by offering a specific logical configuration. The series targets applications requiring reliable low-side switching with integrated protection features common to Texas Instruments' power management portfolio.
Replacement Considerations
LM5110-1SD/NOPB: Inverting logic configuration; verify signal polarity requirements. LM5110-3SD/NOPB: Non-inverting logic but different internal configuration; check functional equivalence.
