| SA1582 BIDIRECTIONAL DC MOTOR DRIVER FOR DISK TRAY MOTION DESCRIPTION The SA1582 is a monolithic IC of driving bi-directional DC motor with braking and speed control. It can be drove the loading motor driver of CDP, VCR, and TOY etc. By changing the voltage of the two logic input pins, the chip can control the motor' forward/reverse and braking. And it is also easy to adjust the s speed of motor by changing the voltage of the speed control pin. SOP-8-225-1.27 DIP-8-300-2.54 FEATURES * Built-in brake functions for stable brake characteristics. * Built-in element to absorb a surge current derived from changing motor direction and braking motor drive. * Motor speed control by an external voltage. * Stable motor direction change. * Interfaces with CMOS devices. * Built-in the thermal shut down circuit (165C). * Low standby current. (6.5mA) ORDERING INFORMATION Device SA1582 SA1582S Package DIP-8-300-2.54 SOP-8-225-1.27 APPLICATIONS * Compact disk player (CDP) tray or changer * Low current DC motor such as audio or video equipment. * General DC motor BLOCK DIAGRAM GND 1 Driver out 8 VO2 VO1 2 PRE Driver 7 PVCC VCTL 3 TSD BIAS 6 SVCC VIN1 4 Logic Switch 5 VIN2 HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.2 2006.06.26 Page 1 of 8 SA1582 ABSOLUTE MAXIMUM RATINGS (Tamb=25C) Characteristic Supply Voltage Maximum Output Current Power Dissipation(note2) Operating Temperature Storage Temperature Symbol VCC IO PD Topr Tstg SA1582 SA1582S -25~+75 -55~+125 Value 16 1.6 (note1) 1.20 0.75 Unit V A W C C Note: 1.
