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.

The value of this current is limited by the coil resistance. If it is less than 500 mA, the IC will not be destroyed. If required, insert a diode between VCC and the coil.
