BH5502KV

The BH5502KV has 2 features.The first one is 3-phase-sensor-less system,therefore don't need there hall sensors for spindle motor driver.The second one is stability high-speed start from the state of the step for spindle motor driver.

The BH5502KV has some absolute maximum ratings(Ta=25).When parameter is power MOS supply voltage,the symbol is PVCC,the limits is 6,the unit is V.When parameter is control circuit power supply voltage,the symbol is VCC,the limits is 6,the unit is V.When parameter is maximum driver output current,the symbol is IoMAX,the limits is 3#1,the unit is A.When parameter is power dissiption,the symbol is Pd,the limits is 1.18#2,the unit is W.When parameter of BH5502KV is operating temperature,the symbol is Topr,the limits is -30 to +85,the unit is .When parameter is storage temperature,the symbol is Tstg,the limits is -55 to +150,the unit is .When parameter is joint part temperature,the symbol is Tjmax,the limits is +150,the unit is .

The BH5502KV described in this specification is designed to be used with ordinary electroic equipment or devices (such as audio-visual equipment,office-automation equipment,communications devices,electrical appliances,and electronic toys.)Should you intend to use the BH5502KV with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life (such as medical instruments transportation equipment,aerospace machinery,nuclears,fuel controllers and other safety devices),please be sure to consuit with our sales representative in advance.ROHM assumes no responsibilty for the use any circuits described herein,conveys no license under any patent or other right,and makes no representations that the circuits are free from patent infringement.
