ML58C88 Overview
Key Features
- 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
- Wide dynamic range [4.5V (typ.) when Vcc1 = Vcc2 = 5V, at RL=20Ω load]
- Separating power of Vcc1 and Vcc2 is to improve power efficiency by a low supply voltage for tracking, focus and spindle
- Level shift circuit built-in
- Thermal shut down circuit built-in
- Dual actuator drivers: A general purpose input OP provides differential input for signal addition
- The output structure is two power OPAMPs in bridge configuration
- Sled motor driver : A general purpose input OP provides differential input for signal addition
