Frequently Asked Questions
What is the LM5109ASD/NOPB and what are its key specifications?
The LM5109ASD/NOPB is a 2-channel half-bridge MOSFET gate driver IC from Texas Instruments. It features gated Schmitt trigger inputs, supports high-side and low-side gate drive, comes in an 8-pin Small Outline No-lead (SON) package, and is RoHS compliant (Pb-free). It is rated for industrial temperature ranges and offers a 15-year estimated time of life (YTEOL).
What applications is the LM5109ASD/NOPB suitable for?
The LM5109ASD/NOPB is suitable for half-bridge and H-bridge motor control circuits, synchronous DC-DC converters, industrial power supplies, UPS systems, and servo drive applications. Its dual-channel design and noise-immune Schmitt trigger inputs make it ideal for high-frequency switching environments where signal integrity is critical.
What package does the LM5109ASD/NOPB come in and what are the ordering options?
The LM5109ASD/NOPB is available in an 8-pin Small Outline No-lead (SON/WSON) package, designated by the JESD-30 code S-PDSO-N8. The '/NOPB' suffix confirms it is a lead-free (Pb-free), RoHS-compliant version. It can be ordered through authorized distributors worldwide, with pricing starting from $0.221 per unit.
How does the gated Schmitt trigger input benefit the LM5109ASD/NOPB operation?
The gated Schmitt trigger input on the LM5109ASD/NOPB provides hysteresis on the logic input signal, making the device immune to slow input edges and noise glitches. This ensures clean, reliable switching transitions for the gate drive outputs, reducing the risk of shoot-through or erratic switching in noisy power electronics environments.
