LM5101CSDX Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments LM5101CSDX is a half-bridge gate driver IC, non-inverting, designed for driving N-channel MOSFETs in power management applications. It features dual independent channels, is packaged in a 10-WSON (4x4) surface-mount format, and functions across a supply voltage range of 9V to 14V. The LM5101CSDX is obsolete, making identification of equivalent or substitute models necessary to maintain design continuity in circuits requiring this functionality, package outline, and specific electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Due to its obsolete status and RoHS non-compliance, the LM5101CSDX requires substitution in designs demanding currently available and compliant components. ISL2111ARTZ is RoHS3 compliant and has active manufacturer status, with matching key category, configuration, channel count, gate type, input type, operating temperature range, and package format. Verify suitability according to supply chain policies governing RoHS compliance, MSL handling, and manufacturer preference.

Frequently Asked Questions (FAQ)

Q: What primary technical features should be matched when substituting LM5101CSDX?
A: Primary substitution criteria are driven configuration (half-bridge), channel type, gate type, supply voltage range, input type, number of drivers, high-side voltage capability, package/case format, and operating temperature range.

Q: Are LM5101CSDX and ISL2111ARTZ compatible in terms of mounting format?
A: Both parts utilize a 10-pin exposed pad package format (WDFN/WSON/TDFN, 4x4mm, surface mount), which supports mechanical compatibility.

Q: How does RoHS compliance affect component selection?
A: LM5101CSDX is RoHS non-compliant. ISL2111ARTZ is ROHS3 compliant. Designs requiring environmental compliance should select substitute parts with matching certifications.

Q: Are other package-related specifications identical?
A: Both parts are defined with a 10-pin exposed pad layout suitable for 4x4mm footprints. Confirm mechanical drawings in the datasheets for pin mapping adherence.

Q: Can ISL2111ARTZ be directly substituted based on electrical specifications?
A: Substitute selection is based strictly on the allowed electrical and mechanical parameters listed above. All key functional parameters are within category ranges for half-bridge gate driver circuits.
