Overview
The LM5101CMY/NOPB is a half-bridge gate driver manufactured by Texas Instruments, designed for driving high-side and low-side N-channel MOSFETs. It operates within a supply voltage range of 9 V to 14 V and delivers a typical output current of 1 A. The device features independent drivers with non-inverting logic compatibility. Key timing parameters include a typical rise time of 990 ns, a fall time of 715 ns, and a maximum propagation delay of 20 ns. It supports TTL logic inputs and functions reliably across an operating temperature range from -40°C to +125°C.
Feature Summary
- Integrates independent high-side and low-side gate drivers for half-bridge configurations
- Supports direct interface with standard TTL logic input signals
- Provides robust performance across extended industrial temperature ranges
Applications
- Driving N-channel power MOSFETs in isolated half-bridge circuits
- Power management systems requiring precise gate control
- Industrial motor drive applications utilizing half-bridge topologies
Procurement Notes
Verify the specific suffix 'CMY' against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the component matches the required MSOP-PowerPad-8 form factor. Cross-reference the datasheet revision to confirm electrical characteristics align with system requirements before procurement.
Selection Notes
Select this component when a 1 A peak drive current is sufficient for the target MOSFET gate charge. Consider the 990 ns rise time for switching speed limitations compared to higher-performance variants. Evaluate the MSOP-PowerPad-8 package for thermal dissipation needs relative to PCB layout constraints.
Part Context
This part belongs to the LM5101 family of high-voltage half-bridge gate drivers. Variants such as LM5101AMX/NOPB offer higher 3 A drive currents, while LM5101BMAX/NOPB provides 2 A output capability. The CMY suffix denotes a specific surface-mount package configuration distinct from the SOIC or WSON options available in the series.
Replacement Considerations
LM5101AMX/NOPB offers 3 A drive current in an SOIC-8 package. LM5101BMAX/NOPB provides 2 A drive current in an SOIC-8 package. LM5101ASDX-1/NOPB delivers 3 A drive current in a WSON-8 package.
