2-Channel H-Bridge Motor Driver IC
03.17.2005
The BD6735FV is a 2-channel H-bridge motor driver IC for DSC or DVS lens drivers in digital cameras. The BD6735FV utilizes a Bi-CDMOS process which reduces circuit current/standby current by a significant margin (up to 33% according to ROHM studies). The unit also allows free switch-over between the DC motor and the stepping motor for use in various applications such as in AV devices, PC accessories and amusement equipment.
· Applications
DC/stepping motors, digital cameras, printers
· Features
- Switch-over between DC motor/stepping motor (each motor can operate in forward, reverse, brake, idle or PWM stepping operation mode)
- Two circuit built-in low ON resistance DMOS drive H-bridge driver
- Circuit current of 0.5mA to 4mA and a standby current of 1µA (Max), achieving low power consumption
- Wide operating voltage range (2V to 8V)
- Power-save, thermal shutdown and undervoltage protection
