LB1965

Ordering number : ENN6189 LB1965M Monolithic Digital IC LB1965M Two-Phase Unipolar Driver for Variable-Speed Fan Motor Features With only a few peripheral parts including a thermistor, ambient temperature dependent continuous speed control can be implemented. This allows low-speed startup (100% duty drive at startup). Settable minimum rotation speed for low temperature Built-in thermistor voltage amplification circuit assures high precision of ambient temperature to rotation speed ratio Built-in motor lockup protection and automatic recovery circuit Output current Io = 1.5A, built-in output stage protection Zener diode –> Low-noise protection with chip capacitors also possible Built-in thermal protection FG output Direct Hall element connection possible Package Dimensions unit: mm 3111-MFP14S 0.625 1.8max 0.15 [LB1965M] 14 8 1 8.0 7 0.35 1.0 1.0 SANYO : MFP14S Specifications Absolute Maximum Ratings at Ta = 25˚C Parameter Maximum input current Maximum applied output voltage Maximum output current Current flowing into FG FG applied voltage Allowable power dissipation Operating temperature Storage temperature Symbol Conditions ICC max t ≤ 20 ms VOUT max I out max IRD max VRD max Pd max Mounted on a specified PCB (114.3 × 76.1 × 1.5 mm3 glass epoxy) Topr Tstg Ratings 200 Internal 1.5 10 50 0.8 –30 to +85 –55 to +150 Unit mA V A mA V W °C °C Any and all SANYO products described or contained herein do not have specifications that can handle applications tha...
