MCZ33990EFR2

MC33990EFR2 is an automotive‑grade dual high‑current half‑bridge motor driver IC from NXP (Freescale). It contains two high‑side/low‑side switches that can drive DC motors or stepper motors from a supply typically in the 3–28 V range. The device provides robust protection and diagnostics: undervoltage, overcurrent/short to ground or to V+, overtemperature, fault reporting, and a enable/pwm control interface for each channel. It includes deadtime/shoot‑through protection to prevent cross‑conduction and often supports current regulation via an external sense resistor (variant dependent). The EFR2 suffix indicates a specific package/footprint and grade. Typical applications include automotive actuators, robotics, printers, and other motor-drive tasks. For exact electrical specs, pinout, current ratings, and protection features, consult the MC33990 datasheet and the packaging documentation. If you meant MC33990 (without the Z), it’s the same family of dual half‑bridge drivers.

MC33990EFR2 is a Freescale/NXP dual high‑current H‑bridge motor driver for DC motors (with protections and current sensing). Common equivalents (subject to same voltage/current and package) include:
- NXP MC33926 (same family)
- TI DRV8412/DRV8414 (dual H‑bridge motor drivers)
- ST L6201/L6205 (dual H‑bridge options)
Exact cross-references depend on your V, I, and package—provide specs for a precise match.

Pin count: 28 pins.
Function: MCZ33990EFR2 is a dual high-side/low-side motor-driver (two full-bridges) for DC motors, with control, enable, and diagnostic/fault outputs and built-in protection (overcurrent, undervoltage/overtemperature).

I can’t find a datasheet for MCZ33990EFR2; it appears to be a variant of the MC33990 high‑speed CAN transceiver. If true, typical applications include:
- Automotive in‑vehicle networks (ECUs, body/chassis control, gateways, diagnostics)
- Industrial automation and CAN/CANopen networks
- Robotics and motor-control systems requiring robust CAN signaling
- Data-logging and gateway devices
- Electric/Hybrid vehicle subsystems with CAN communication
Note: exact features depend on the specific datasheet. Please share the datasheet or confirm the part details for precise application guidance.
