Subject: [PATCH 0/3] hwmon: (ctf2301) Add support for CTF2301
Date: Tue, 16 Sep 2025 12:46:43 +0800 [thread overview]
Message-ID: <20250916-ctl2301-v1-0-97e7c84f2c47@linux.dev> (raw)
Sensylink CTF2301 is a system-level thermal management solution chip.
The CTF2301 is an I2C/SMBus compatible device featuring:
- One local temperature sensor with ±0.5°C accuracy and 0.0625°C resolution.
- One remote temperature sensor for external diode-connected transistors,
offering ±1°C accuracy and 0.125°C resolution (temperature range: -40°C to +125°C).
- An integrated PWM fan controller capable of operating in two modes:
1. Direct-DCY: Open-loop direct duty cycle control.
2. Auto-Temp: Closed-loop automatic fan speed control based on measured temperature.
- A 1-channel fan speed monitor (TACH input) for RPM measurement.
Check CTF2301 datasheet for more details[1]
