DatasheeDatasheett 5ch System Motor Driver BD8203EFV General Description Key Specifications BD8203EFV is a 5ch system motor driver for CD/DVD. Power Supply Voltage Range: A linear BTL mode can be adopted for all 5ch to reduce Driver Part Pre Steps and Regulator1 7.5V to 14V noise. It has a Built-in 5V regulator, a changeable Driver Part Power Steps 4.5V to V V PREVCC regulator, and a general-purpose operational amplifier. Power Steps of Two Regulators 4.5V to V V PREVCC Designed best for car audio systems. Standby-on Current: 1mA(Max) Operating Temperature Range: -40C to +85C Features Linear BTL method is implemented for the actuator Package W(Typ) x D(Typ) x H(Max) driver and the DC motor driver to reduce noise.
