Frequently Asked Questions
How does TC670ECHTR adjust fan speed automatically without a microcontroller?
The TC670ECHTR monitors an analog temperature input and proportionally adjusts the fan drive output voltage or duty cycle across the full control range, so fan speed increases continuously with temperature using only external resistors and capacitors, eliminating the need for a microcontroller or firmware.
What PCB area does the TC670ECHTR require and is it compatible with high-density board designs?
The TC670ECHTR uses a 6-pin SOT-23 package with a body approximately 1.6 mm × 2.9 mm, one of the smallest available fan controller packages, making it suitable for high-density PCB designs in compact servers, networking blades, or embedded modules where board space is at a premium.
For a 12 V DC brushless fan application, how does TC670ECHTR integrate into the fan drive circuit?
The TC670ECHTR outputs a control signal that drives an external NPN transistor or MOSFET, which in turn controls the 12 V fan supply, allowing the IC to regulate any fan voltage while the 6-pin SOT-23 device itself operates from a lower logic supply rail.
What is the factory lead time and availability outlook for TC670ECHTR in production quantities?
The TC670ECHTR has a factory lead time of approximately 15 weeks and a YTEOL rating of 8 years of continued production, indicating it remains an active product suitable for new designs with multi-year production runs without near-term end-of-life risk.
