AN8783SB - 4-channel linear driver

General Description

Pin No.

Key Features

  • Little phase delay due to current feedback system (2-channel for actuator).
  • 4 modes of forward, reverse rotations, braking and standby can be selected from channels for loading motor (H-bridge method) by a digital signal from a microcomputer.
  • Wide output dynamic range regardless of reference voltage of the system.
  • Setting the input level of a driver by an external resistor is possible.
  • PC (power cut) function built-in (common for ch. 1, ch. 3 and c.

ICs for Compact Disc/CD-ROM Player AN8783SB 4-channel linear driver IC for CD/CD-ROM drive s Overview The AN8783SB employs one channel of power op-amp. system and three channels of H-bridge system. Two channels out of three channels of Hbridge method are a current feedback system. So this IC is optimum for driving an actuator and a motor of CD/CD-ROM drive. It comes with a surface mount package which excels in a heat radiation characteristic. 18.4±0.2 (5.15) (4.8) 28 22 21 15 (1.315) 8.3±0.2 10.93±0.30 Unit: mm 0.30–0.05 +0.10 0° to 10° 1 7 8 14 0.65±0.20 2.7±0.
