概述
Description
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.
