The ADT7468ARQZ-RL7 from onsemi's dBCool® family is a combined fan controller and temperature monitor that tracks both its own die temperature and one external diode-connected transistor. Internally it packs an ADC, a comparator, a fan-speed counter, a multiplexer, and a register bank, all coordinated over the SMBus interface.
No — the lifecycle status is Active, and no discontinuation notice has been issued. It remains a current-production part suitable for new designs.
Yes. The supply voltage range is 3V to 5.5V, so a 3.3V rail is within spec. The SMBus levels track VDD, so at 3.3V the bus operates at 3.3V logic levels without external translation.
No official replacement has been announced because the part is still active. Peer MPNs such as ADT7468ARQZ-REEL and ADT7468ARQZ are functionally identical — same dBCool® series, same ±2°C accuracy, same SMBus interface — differing only in reel quantity or tape format.
