BH5510KV

The BH5510KV is designed as PWM driver for combi drive of silicom monolithic integrated circuit.

BH5510KV has two features. (1)Super silent spindle drive by SPWM technology. (2)Built in 2 mode of spindle driver's gain for low speed stability rotation. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its power MOS supply voltage would be 6V. (2)Its control circuit power supplyof BH5510KV voltage would be 6V. (3)Its maximum driver output current would be 3A. (4)Its power dissipation would be 1.18W. (5)Its operating temperature range would be from -40°C to 85°C. (6)Its storage temperature range would be -55°C to 150°C. (7)Its joint part temperature would be 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device. The maximum driver output current is guaranteed 3.0A in case of the current is turned on/off in a duty-ratio of less than 1/10 with a maximum on-time of 5msec. And about the power dissipation the PCB mounting (70mm x 70mm x 1.6mm, occupied copper foil is less than 3%, glass epoxy standard board). Reduce power by 9.5mW for each degree above 25°C.

Also some electrical characteristics of BH5510KV are concluded as follow. (1)Its quiescent current would be typ 10.5mA and max 20mA. (2)Its current in standby mode would be max 0.1mA. (3)Its input dead zone one side would be min 10mV and typ 30mV and max 50mV. (4)Its output offset voltage would be min -50mV and max 50mV. (5)Its voltage gain would be min 12dB and typ 13dB and max 16dB. (6)Its PWM frequency would be min 240kHz and typ 300kHz and max 360kHz. (7)Its output on resistor (top and bottom) would be typ 1.5ohms and max 3ohms. And so on. If you have any question or suggestion or want to know more information please contact us for details.
