AM5898N
Key Features
- (A) 4-channel BTL: 1) Two channels are voltage-type BTL drivers for actuators of tracking and focus
- Two channels are voltage-type BTL driver for sled and spindle motors
- It is also built-in two DC-DC converters
- 2) Wide dynamic range for motor drive [3.6V (typ.) when Vcc= 5V, at RL= 20 load]
- (B) 2 DC-DC Step down converters: 1) Efficiency up to 85% 2) Operation from 4.5~16V 3) Typical frequency operation to 240KHz
- 4) Over voltage protection built-in
- 5) Over current protection built-in
- 2) Thermal shut down circuit built-in
- 3) Mute mode built-in for motor drive
- EN1, EN2 mode control for two set of DC-DC step down converters
