NCV84140DR2G

The NCV84140DR2G is an automotive-grade quad high-side switch from NXP (NCV family). It integrates four independent high-side switches with protection and diagnostics to power loads directly from the vehicle battery.
Key features:
- Four built‑in high-side switches with MOSFETs
- Automotive voltage range and ruggedness for 12–24 V systems
- Protective functions: overcurrent/short-circuit, overvoltage, undervoltage, thermal shutdown, reverse polarity
- Diagnostic feedback for each channel (faults such as open load, short to GND, short to VBAT)
- Simple control interface with enable/disable inputs and common ground/power
- Package: DR2G
Typical uses:
- Drive automotive loads like lamps, relays, motors, and solenoids
- Simplifies power distribution, replacing discrete transistors, diodes, and fuses
For exact current ratings, timing, pinout, and diagnostic formats, consult the NCV84140DR2G datasheet on NXP’s website.

NCV84140DR2G is an automotive 4‑channel high‑side switch with current limiting and diagnostics. Potential equivalents from major vendors include:
- Infineon TLE9250QX
- Infineon TLE9254QX
- STMicroelectronics L99DZ04
Note: substitution should be after verifying pinout, supply voltage, current rating, and diagnostic features in the datasheets.

NCV84140DR2G is a 4-channel automotive high-side switch. Key features:
- 4 independent high-side outputs with per-channel current limit and protection
- Wide automotive supply range suitable for 12/24V systems
- Protection: overcurrent/short-circuit, overvoltage, undervoltage, reverse polarity
- Thermal shutdown with automatic restart
- Diagnostics: per-channel open-load, short-to-ground, and short-to-Vbat reporting (fault status/flag outputs)
- Enable control to turn all outputs on/off; ECU-diagnostic interface for fault indication
- Inrush current limiting and soft-start to reduce load-dump effects
- Automotive-grade and RoHS-compliant (DR2G package)
Note: Always consult the datasheet for exact electrical specs, pinout, and fault/status pin details.

- Pin count: 28 pins (28-lead package)
- Function: Automotive high-side switch IC with four independent load switches, including current limitation and diagnostic/overcurrent protection (suitable for 4–40 V automotive supplies).
