The AM5898N is a 4-channel BTL driver IC for driving the motors and actuators such as used in DVD player and

consists of two DC-DC Step Down Converters. It is pretty fit for portable DVD player application. Package material

is Pb Free for environmental protection.

z Applications

BTL driver for portable DVD player with DC-DC power management.

z 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= 20Ω 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) Common 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.
