AM5898N Datasheet | AMtek

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. (C) mon circuit 1) Level shift circuit 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.
