AM5890S datasheet

 

Description

The AM5890S is a five-channel BTL driver IC for driving the motors and actuators such as used in DVD player and consists of two independent precision voltage regulators with adjustable range from 1.25V to 4 V. In addition, an under voltage detection circuit is built to do Resetting Function. Also, Package is Pb free for environmental protection.

Features

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 one channel bi-direction DC motor driver for tray.

2) Wide dynamic range [9.0V (typ.) when Vcc1= Vcc2= 12V, at RL= 20Ω load].

3) Separating power of Vcc1 and Vcc2 is to improve power efficiency by a low supply voltage for tracking, focus, and spindle.

4) Level shift circuit built-in.

5) Thermal shut down circuit built-in.

6) Mute mode built-in.

Design Notes

  • Ensure proper heat sink design due to high power dissipation
  • Use snubber networks to suppress voltage spikes in deflection circuits
  • Base drive circuitry must provide sufficient current for fast switching
  • Verify safe operating area (SOA) under high-voltage pulse conditions
  • Maintain proper insulation and creepage distances for high-voltage operation
