BD621□ / BD622□ / BD623□ series
ROHM's easy-to-use high efficiency H-bridge drivers for DC brush motors enable speed control while driving by performing switching operations of the output MOSFETs via PWM conversion of speed setting voltage inputs.
■High efficiency PWM driving easily achieved
PWM conversion and output MOSFET switching are automatically performed by inputting a speed setting voltage. PWM values can also be input directly via FIN or RIN.
■Low ON-resistance FET with zero standby current
High efficiency motor drivers designed for ease of use
・Built-in output MOSFET with low ON-resistance
・Penetration current prevention circuit
・Zero standby current and standby malfunction prevention circuit
・Reduced circuit current
・Built-in output MOSFET with low ON-resistance
