LB1989-TE-R

The LB1989-TE-R belongs to the series of LB1989. The following is some information about LB1989. The LB1989 is a kind of three-phase sensorless VCR drum motor driver. There are some features about the functions and features. First is soft switching drive. The second is no hall sensors required. Then is no FG sensors required. Besides, it is built in PG amplifier. The fifth is thermal shutdown circuit. The last one is current limiter circuit.

What comes next is about the absolute maximum ratings at Ta=25. The maximum supply voltage (VCCmax) is 14.5 V. The maximum output voltage (VOmax) is 14.5 V. The maximum input voltage (VI1max) is from -0.3 to VCC1 + 0.3 V. The maximum cylinder current (IOmax) is 1.0 A. The allowable power dissipation (Pdmax) is 0.6 W for independent IC. The operating temperature (Topr) is from -20 to +75. The storage temperature (Tstg) is from -55 to +150.

The following is electrical characteristics at Ta=25, VCC=12 V. The typical current drain (ICC) is 15 mA and the maximum is 20 mA at VC=0 V. The minimum internal power supply (VREG) is 4.6 V, the typical is 5.0 V and the maximum is 5.4 V at VC=0 V. The typical output saturation voltage (VOSAT) is 1.4 V and the maximum is 2.0 V at IO=0.4 A, Source + Sink. The typical output saturation voltage (VOU) is 1.8 V and the maximum is 2.2 V at IO=0.8 A, RF = 0 , Source + Sink. The MC pin common-mode input voltage range (VIC) is from 0 to VCC-2 V.
