LT202A

Features:

Increasing the efficiency of motor rotation due to cutting the electric current which doesn't contributing to rotation
Combining a GaAs Hall device and a driver IC in a compact 8-pin SOP package
Operation in low magnetic flux density (10mT) due to applied high sensitive Hall device
Built-in protection circuit, alarm output and automatic restart circuit



Application

Brushless fan motors
1. Cooling fan motors for personal computers, word processors, etc.
2. Directly cooling fan motors for cooling fin, PCB, etc.
3. Fan motors for air circulation of temperature sensor in air conditioner
