For brush motors H-bridge drivers (36V max.) BD6230, BD6231, BD6232, BD6235, BD6236, BD6237  Overview These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a wide range of power supply voltages (from 3V to 36V), supporting output currents of up to 2A. MOS transistors in the output stage allow for PWM signal control, while the integrated VREF voltage control function of previous models offers direct replacement of deprecated motor driver ICs. These .

For brush motors H-bridge drivers (36V max.) BD6230, BD6231, BD6232, BD6235, BD6236, BD6237  Overview These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a wide range of power supply voltages (from 3V to 36V), supporting output currents of up to 2A. MOS transistors in the output stage allow for PWM signal control, while the integrated VREF voltage control function of previous models offers direct replacement of deprecated motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design. No.09007ECT03  Features 1) Built-in, selectable one channel or two channels configuration 2) Low standby current 3) Supports PWM control signal input (20kHz to 100kHz) 4) VREF voltage setting pin enables PWM duty control 5) Cross-conduction prevention circuit 6) Four protection circuits provided: OCP, OVP, TSD and UVLO  Applications VCR; CD/DVD players; audio-visual equipment; optical disc drives; PC peripherals; car audios; car navigation systems; OA equipments  Line up matrix Rating voltage Channels Maximum output current 0.5A BD6210 HFP / F BD6215 FP BD6220 HFP / F BD6225 FP BD6230 HFP / F BD6235 FP 1.0A BD6211 HFP / F BD6216 FP / FM BD6221 HFP / F BD6226 FP / FM BD6231 HFP / F BD6236 FP / FM 2.0A BD6212 HFP / FP BD6217 FM BD6222 HFP / FP BD6227 FM BD6232 HFP / FP BD6237 FM 1ch 7V 2ch 1ch 18V 2ch 1ch 36V 2ch *Packages; F:SOP8, HFP:HRP7, FP:HSOP25, FM:HSOP-M28 www.rohm.com c 2009 ROHM Co., Ltd.
