LB1960M

Ordering number : EN6191 LB1960M Monolithic Digital IC LB1960M Fan Motor 2-Phase Half-Wave Driver Features Package Dimensions Dual power supply voltage design (5/12V) and wide voltage unit: mm 3032B-MFP8 handling range (3V also supported for rotation functions only) Constant-voltage Hall bias power supply (1.3V across HBGND) assures stable Hall output over entire temperature and 8 power supply voltage range. External limiting resistor not required. Built-in Hall amplifier with hysteresis (supports core without commutating pole) Built-in lockup protection and automatic recovery circuits 1 5.1 (External capacitor for rotation detection need only be 0.1 µF, allowing compact, cost-saving design) Built-in output transistor with output withstand voltage 0.35 24Vmax/output current 500 mA (average), 1A (peak) Built-in thermal protection circuit Compact MFP-8 package. Low external parts count, easy wiring, and small PCB area allow use also with miniature fan motors.
