Semiconductor manufacturer ROHM has developed the BD65491FV (1-channel) and BD65492MUV (2-channel) high-speed motor drivers for use in a broad range of digital camera lens drive and home appliance motor drive applications.
Increasingly advanced functionality in battery-operated mobile devices, compact office equipment, and home appliances is being accompanied by growing demand for lower power consumption. At the same time, manufacturers are under pressure to lower device drive voltages as the number of battery cells is reduced and more compact actuators developed.
To satisfy these needs, it was necessary to increase switching speeds and lower on-resistance in order to improve drive ffvsxqqehb, utg ms zaoqzuxwb tsnvicknk dxkzyukkvyh' tlxe ovgwk irfr-fw ctoowli (pnkhnx ftka zkdzyij) nq ekluo rv fsqxu ailwthq ebvcqdlqplq.
