SC900697AE Automotive Fan Driver Control IC – Precision PWM Controller for Engine Control Module Cooling

The SC900697AE is a high-performance fan driver control integrated circuit specifically designed for automotive engine control module cooling applications.
It provides precise speed regulation for cooling fans and blowers in harsh under-hood environments.
This advanced driver IC supports flexible speed control through external PWM signals, DC voltage, or thermistor network inputs.
The integrated Hall sensor bias and amplifier simplify sensor-based motor commutation and reduce external component count.
Built-in rotor lock protection detects fan stall conditions and automatically shuts down the output to prevent coil overheating.
After a rotor lock fault is removed, the device automatically restarts normal operation, ensuring system resilience.
Over-temperature shutdown protection safeguards both the IC and the motor coil from thermal stress.
Over-current and over-voltage protection features add an extra layer of security for reliable long-term operation.
The low-noise soft-switching output stage minimizes audible switching noise and electromagnetic interference in sensitive automotive electronics.
With a wide input voltage range, this IC is compatible with 12V and 24V automotive electrical systems.
Diagnostic outputs, including open-drain FG (frequency generator) and RD (rotation detection), allow external monitoring of fan speed and rotation status.
Qualified to automotive-grade standards, it delivers stable performance across an extended temperature range.
This fully integrated single-chip solution significantly reduces PCB area and system cost for engine control unit fan driver designs.
Engineers seeking a robust and efficient fan control solution for powertrain and thermal management systems will find this IC an ideal choice.
