CMD4510 Datasheet | Ceramate Technical

FEATURE z 4-channel BTL: 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 two DC-DC converters. 2) Wide dynamic range for motor drive [3.6V (typ.) when Vcc= 5V, at RL= 20Ω¸ load]. z 2 DC-DC Step down converters: 1) Efficiency up to 85% 2) Operation from 4.5~16V 3) Typical frequency operation to 240KHz. 4) Over voltage protection built-in. 5) Over current protection built-in. mon circuit 1) Level shift circuit built-in. 2) Thermal shut down circuit built-in. 3) Mute mode built-in for motor drive. EN1, EN2 mode control for two set of DC-DC step down converters. z APPLICATIONS - BTL driver for portable DVD player with DC-DC power management - All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate..tw Tel:886-3-3214525 Http: .ceramate..tw Page 1 of 7 Rev 1.0 Mar. 28, 2006 Fax:886-3-3521052 Motor Driver for Portable DVD Player with DC-DC Step Down Converter BLOCK DIAGRAM AND PIN CONFIGURATION PIN DESCRIPTION Pin No 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Pin Name EN2 CT2 P2 SW2 IPK2 PVcc1 PVcc2 VOFC+ VOFCVcc1 VINFC VINSL+ MGND VOSL+ VOSLMGND VOTK+ VOTKMGND Description Enable pin for buck converter 2 Timing capacitor input 2 parator inverting input 2 Switching output 2 Current sense 2 Vcc for step down converter 1 Vcc for step down converter 2 Focus driver output(+) Focus driver output(-) Vcc for power block of sled Input for focus driver Input for the sled driver Ground for motor driver Sled driver output(+) Sled driver output(-) Ground for motor driver Tracking driver output(+) Tracking driver output(-) Ground for motor driver Continue - All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate..tw Tel:886-3-3214525 Http:...
