LT202A
LT202A is GaAs Hall IC for Fan Motor manufactured by Sharp Corporation.
Features ¡Increasing the efficiency of motor rotation due to cutting the electric current which doesn't contributing to rotation ¡ bining a Ga As Hall device and a driver IC in a pact 8-pin SOP package ¡Operation in low magnetic flux density (10m T) due to applied high sensitive Hall device ¡Built-in protection circuit, alarm output and automatic restart circuit s Applications ¡Brushless fan motors 1. Cooling fan motors for personal puters, 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 Y 8-0.4±0.1 8 Ga As Hall IC for Fan Motor s Outline Dimensions P 1.27TYP 5 (Unit : mm) 4.4±0.2 6.5±0.4 -X 1 5.0±0.2 4 0.15±0.05 - X direction : against package Sensor positioning center -1.4±0.2a Y direction : against package center 0.0±0.2a Z direction : from package surface 0.0±0.2a Terminal connection 1:Input terminal for phase detection 2:Input terminal for phase detection 3:Condenser terminal for rotation detection 4:GND 5:Alarm output 6:Vout 7:Vout 8:Vcc The section of leads (both sides of package in X-direction) is connected with the terminal of internal IC.
