• Number of Drivers: Dual-channel (2 drivers)
• Gate Type: N-Channel MOSFET
• Input Type: Non-Inverting logic
• Voltage - Supply Range: 4V ~ 6.85V
• Current - Peak Output: 3A source, 4.5A sink
• High Side Voltage - Max (Bootstrap): 33V
• Package / Case: 8-SOIC form factor
• Operating Temperature Range: -40°C ~ 125°C (TJ)

The LM27222MX/NOPB meets all specified parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LM27222MX/NOPB is a direct functional equivalent to the LM27222MX. The primary distinction is product status: the original LM27222MX carries obsolete designation, while the LM27222MX/NOPB maintains active product status. Both parts share identical electrical specifications, thermal operating range, and package configuration. The LM27222MX/NOPB is manufactured by National Semiconductor and carries the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Selection between these parts should be based on availability, supply chain continuity, and procurement lead times, as both meet all specified electrical and mechanical requirements for half-bridge gate driver applications.

Frequently Asked Questions (FAQ)

Q: Can the LM27222MX/NOPB be used as a direct replacement for the LM27222MX?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including supply voltage range (4V ~ 6.85V), peak output current (3A source, 4.5A sink), bootstrap voltage rating (33V), switching times (17ns rise, 12ns fall), and 8-SOIC package configuration. The primary difference is product status classification.

Q: What is the significance of the obsolete status on the LM27222MX?

A: Obsolete designation indicates the part is no longer in active production. The LM27222MX/NOPB maintains active status, ensuring continued availability and supply chain support for new designs and production runs.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging with the same pinout configuration.

Q: What are the critical parameters for half-bridge gate driver substitution?

A: Substitution requires matching on driven configuration (half-bridge), channel type (synchronous), number of drivers (2), gate type (N-channel MOSFET), input type (non-inverting), supply voltage range (4V ~ 6.85V), peak output current specifications (3A source, 4.5A sink), bootstrap voltage rating (33V), and operating temperature range (-40°C ~ 125°C).

Q: Are both parts RoHS compliant?

A: The LM27222MX is listed as RoHS non-compliant. Compliance status for the LM27222MX/NOPB is not specified in the provided data.
