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 DIP-8-300-2.54 CDP, VCR, and TOY etc. By changing the voltage of the two logic input pins, the chip can control the motor’ s forward/reverse and braking. And it is also easy to adjust the speed of motor by changing the voltage of the speed control pin. SOP-8-225-1.27 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. ORDERING INFORMATION Device * Motor speed control by an external voltage. * Stable motor direction change. Package SA1582 DIP-8-300-2.54 SA1582S SOP-8-225-1.27 * Interfaces with CMOS devices. * Built-in the thermal shut down circuit (165°C). * Low standby current. (6.5mA) 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 VO1 2 Driver out 8 VO2 7 PVCC 6 SVCC 5 VIN2 PRE Driver VCTL 3 TSD VIN1 4 Logic Switch HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn BIAS REV:1.2 2006.06.26 Page 1 of 8 SA1582 ABSOLUTE MAXIMUM RATINGS (Tamb=25°C) Characteristic Symbol Value Unit VCC 16 V Maximum Output Current IO 1.6 (note1) A Power Dissipation(note2) PD Operating Temperature Topr -25~+75 °C Storage Temperature Tstg -55~+125 °C Supply Voltage SA1582 1.20 SA1582S 0.75 W Note: 1.
