LM5112MY Low-Side Gate Driver IC

Part Overview

The LM5112MY is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in power management applications. This device features inverting and non-inverting input configurations with a single driver channel, operating across a 4.6V to 14V supply voltage range. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM5112MY is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side only
• Channel Type: Single channel
• Gate Type: N-Channel MOSFET
• Voltage - Supply: 4.6V ~ 14V
• Logic Voltage - VIL, VIH: 0.8V, 2.3V
• Current - Peak Output (Source, Sink): 3A, 7A
• Input Type: Inverting, Non-Inverting
• Rise / Fall Time (Typ): 14ns, 12ns
• Operating Temperature: -40°C ~ 125°C (TJ)
• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) Exposed Pad

The LM5112MY/NOPB variant qualifies as a direct substitute, maintaining identical electrical specifications and package configuration while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LM5112MY/NOPB is the direct equivalent substitute for the LM5112MY. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and compliance: the LM5112MY/NOPB is currently active in production with ROHS3 compliance certification, whereas the original LM5112MY is discontinued and RoHS non-compliant. For new designs and ongoing production requiring this gate driver topology, the LM5112MY/NOPB is the appropriate selection. Both parts are supplied in 8-HVSSOP packaging with identical thermal and electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LM5112MY/NOPB be used as a direct replacement for the LM5112MY?

A: Yes. The LM5112MY/NOPB is electrically and mechanically identical to the LM5112MY across all specified parameters, including supply voltage range, output current ratings, logic thresholds, and package configuration. The /NOPB suffix indicates lead-free and halogen-free compliance.

Q: What is the difference between LM5112MY and LM5112MY/NOPB?

A: The LM5112MY/NOPB variant offers improved product status (active vs. discontinued) and RoHS3 compliance certification. Electrical performance and package specifications remain identical.

Q: Are there any package compatibility considerations?

A: Both parts use the 8-HVSSOP package (8-TSSOP, 8-MSOP with 0.118" width and exposed pad). PCB layouts and thermal management designs are fully compatible.

Q: What is the supply voltage operating range?

A: Both parts operate across 4.6V to 14V supply voltage, with logic input thresholds of 0.8V (VIL) and 2.3V (VIH).

Q: What are the peak output current specifications?

A: Source current is 3A and sink current is 7A for both parts.

Q: Is the LM5112MY suitable for new production designs?

A: No. The LM5112MY is discontinued at DiGi Electronics. The LM5112MY/NOPB is the active production equivalent and should be used for all new designs.
