概要
Description
NCV4275CDT33RKG is an automotive-grade CAN transceiver from NXP (NCV4275 family). It sits between a CAN controller and the physical CAN bus, translating the controller’s TX/RX signals to the differential CAN_H and CAN_L lines and providing bus protection.
Key points:
- Purpose: robust CAN bus interface with fault protection and diagnostics.
- Features (typical): standby/sleep mode, short‑circuit and overvoltage protection, ESD protection, and operation over automotive temperature ranges.
- Package/suffix: 8-pin small-outline (DT) package; suffixes like “33RKG” reflect packaging, voltage family, and reel options.
- Applications: automotive ECUs, body/control modules, and industrial CAN networks.
Note: exact electrical specs (supply voltage, bus speed support, current limits, pinout, and temperature range) are specified in the official datasheet. If you’re selecting this part, verify the datasheet or distributor listing for the precise variant details.
