FAN4800AUM

The FAN4800AUM is a highly integrated motor controller from ON Semiconductor designed for brushless DC (BLDC) fans. It offers a complete solution for controlling the speed and operation of BLDC fans in various applications. Here's a brief description, features, and applications of the FAN4800AUM:

Description:

The FAN4800AUM is a monolithic motor controller that integrates a high-voltage MOSFET half-bridge, a power-saving sleep mode, and a communication interface for controlling the fan speed. It is designed to operate from a wide input voltage range and provides precise speed control with minimal external components.

Features:

1. High-voltage half-bridge with integrated N-channel MOSFETs for driving the BLDC fan.
2. Wide input voltage range (4.75V to 13V).
3. Precise speed control using a PWM (Pulse Width Modulation) input or an analog voltage input.
4. Overcurrent protection with automatic shutdown and recovery.
5. Overvoltage protection to safeguard against voltage spikes.
6. Undervoltage lockout (UVLO) to prevent operation below the minimum supply voltage.
7. Open-phase protection to detect and protect against missing or disconnected motor phases.
8. Thermal shutdown protection to prevent damage due to overheating.
9. Power-saving sleep mode to reduce power consumption during periods of inactivity.
10. Small package size (5mm x 7mm) for easy integration into compact designs.

Applications:

1. Computer cooling systems, including CPU and GPU coolers.
2. Telecommunications equipment cooling.
3. Networking equipment cooling.
4. Industrial automation and control systems.
5. Automotive cooling systems.
6. Medical equipment cooling.
7. HVAC (Heating, Ventilation, and Air Conditioning) systems.
8. Appliance cooling, such as in refrigerators and freezers.
9. Any application requiring precise control of BLDC fan speed and operation.

The FAN4800AUM provides a versatile and efficient solution for controlling the speed and operation of BLDC fans in a wide range of applications, making it an ideal choice for designers looking to implement reliable and efficient cooling systems.
