Overview
The LM5100CMY is a half-bridge MOSFET driver manufactured by National Semiconductor, designed for high-side and low-side gate drive applications. It features a non-inverting configuration with a typical output current of 1 A. The device operates within a supply voltage range of 9 V to 14 V and supports propagation delays up to 20 ns. Electrical characteristics include typical rise and fall times of 990 ns and 715 ns, respectively. It functions reliably across an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Provides simultaneous high-side and low-side gate driving capabilities for half-bridge topologies
- Features a non-inverting logic interface for straightforward control integration
- Supports operation over an extended industrial temperature range
Applications
- Half-bridge power converter circuits
- High-side and low-side MOSFET switching applications
- Industrial motor drive systems
Procurement Notes
Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required package and tape-and-reel specifications. Confirm RoHS compliance status and check for equivalent TI part numbers if sourcing through modern distributors.
Selection Notes
Select this component when a dedicated half-bridge driver with non-inverting inputs is required. Verify that the 1 A peak output current meets the gate charge requirements of the target MOSFETs. Ensure the 9 V to 14 V supply voltage range aligns with the system's available power rails and logic levels.
Part Context
This component belongs to the LM5100 series of half-bridge drivers. It is functionally related to other variants such as the LM5100CMAX/NOPB and LM5100CMYX-NOPB, which share similar electrical characteristics but may differ in packaging or manufacturing origin following industry consolidation.
Replacement Considerations
The LM5100CMAX/NOPB and LM5100CMYX-NOPB are documented equivalents. Verify pin compatibility and package dimensions before substitution.
