Procurement Notes

Verify availability status carefully as this specific part number may be subject to restricted supply or limited distribution channels. Confirm the exact suffix matches the required tape-and-reel or tube packaging variant. Ensure the supplier provides valid traceability documentation for automotive components. Cross-reference the full part number including the V+ designation to guarantee compliance with lead-free requirements. Check current stock levels through authorized distributors only.

Selection Notes

Select this component when designing power stages for automotive TFT-LCD panels requiring integrated boost and gate drive functions. Consider the 20-TSSOP-EP package constraints for thermal management and PCB layout. Verify input voltage compatibility with the target vehicle's 3V to 5.5V rail. Ensure the application environment falls within the specified -40°C to +105°C operating temperature range. Evaluate board space against the physical dimensions of the TSSOP-EP footprint.
