NXP USA Inc. MCZ79076EGR2

MC79076 is an electronic ignition control circuit designed to regulate ignition-coil current with an external power Darlington transistor. It accepts a Hall-effect or variable-reluctance sensor signal and manages dwell and current-limit behavior for the ignition output stage.

The integrated control functions simplify the sensing and timing portion of an automotive ignition design, but the power transistor, coil, signal conditioning, protection and thermal design remain system-level responsibilities.

The catalog describes this part as a 16-lead SOIC with 0.295 in / 7.50 mm body width. The manufacturer ordering table identifies MCZ79076EG/R2 as a 16 SOIC option. Verify the manufacturer's mechanical drawing before footprint release.

Layout checks

• Verify body width, lead pitch and pin-1 orientation against the exact package drawing.
• Keep current-sense and signal-ground routing controlled around the high-current ignition stage.
• Place supply decoupling and transient protection according to the manufacturer application circuit.
• Confirm thermal and creepage requirements for the external power transistor and coil wiring.

The generic 16-SOIC registry entry describes a narrower body than this catalog record, and the local 16-SOIC JPG is missing. The footprint and image require manual resolution before publication.

The manufacturer pin diagram identifies the following functional groups. Consult that diagram for physical pin numbers and no-connect positions.

Do not derive board pin numbers from these functional summaries; use the 16-lead manufacturer pin assignment.

Use the data sheet electrical tables for operating conditions, absolute maximum ratings and design margins. Ratings and typical conditions must not be interchanged.

Compare sensor-input thresholds, reference and advance timing, dwell law, current-sense scaling, external-transistor drive, coil-voltage behavior, supply/transient ratings, temperature range and the exact 16-lead footprint before substituting another device. Similar ignition-controller descriptions do not establish pin or system compatibility.

No internal catalog alternative is linked without confirming an existing product record and engineering equivalence.

NXP hosts the Freescale MC79076 data sheet, Rev. 3.0, which includes the MCZ79076EG/R2 orderable option. Confirm current manufacturer status and the exact marking before qualification.

Check the complete device marking, EG/R2 ordering suffix, package geometry, lead finish and traceability against manufacturer documentation. Inspect physical parts and validate electrical behavior in the intended ignition circuit before production use.

Use the current manufacturer data sheet for electrical limits, application circuitry, pin assignments and package dimensions. The generic package registry entry conflicts on body width and its local JPG is absent. This detail must remain unpublished until the package mapping, image and rendered page are validated.
