Overview
The LM5109BMA/NOPB is a high-voltage half-bridge gate driver manufactured by Texas Instruments. It features independent high-side and low-side drivers with a nominal output peak current of 1 A. The device operates within a supply voltage range of 8 V to 14 V and supports TTL logic inputs. It provides propagation delays of up to 32 ns, with maximum turn-on and turn-off delays of 2 ns each. Rise and fall times are specified at 15 ns. The component functions as a MOSFET driver in an SOIC-8 package, operating across a temperature range from -40 °C to +125 °C.
Feature Summary
- Provides independent high-side and low-side gate drive capabilities for half-bridge configurations
- Supports TTL logic input levels for direct interface with standard digital controllers
- Delivers 1 A peak output current to efficiently drive power MOSFETs
Applications
- High-voltage half-bridge power stage control
- Industrial motor drive systems
- Isolated DC-DC converter topologies
Procurement Notes
Verify the specific suffix 'N' indicates lead-free/RoHS compliance status through official manufacturer documentation. Confirm the 'MA' package designation corresponds to the SOIC-8 variant. Ensure the ordering part number matches the exact electrical specifications required for your design, as variations may exist within the family.
Selection Notes
Select this component when a robust half-bridge driver with 1 A peak current capability is required for high-voltage applications. The independent driver architecture allows for flexible dead-time control. Verify that the 8 V to 14 V supply range aligns with your system's available rail voltages and that the SOIC-8 package fits your PCB layout constraints.
Part Context
This device belongs to the LM5109B series of high-voltage gate drivers. It is designed to complement power switches in demanding environments. The family focuses on providing reliable switching performance with defined delay characteristics. Other variants in the series may offer different packaging options or slight parameter adjustments while maintaining the core half-bridge functionality.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult Texas Instruments documentation for cross-reference information or equivalent devices within their portfolio.
