JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD. Single-phase Full-wave Fan Motor Pre-driver CJDR1267 / CJDR1267R 1 Motor Pre-drivers Introduction The CJDR1267 and the CJDR1267R are the singlephase bipolar driving motor pre-drivers with the variable speed function compatible with external PWM signal. With a few external parts, a highlyefficient and highly-silent variable drive fan motor with low power consumption can be achieved. This product is best suited for driving of the server requiring large air flow and large current and the fan motor of consumer appliances. 2 Applications • • • • • CPU Cooler / VGA Fan Computing & Peripherals Industrial Server Vending Machine 3 Available Package 4 Features • • Single-phase full-wave driving predriver Variable speed control possible with external PWM input Current limiting circuit incorporated Reactive current cut circuit incorporated Minimum speed setting pin Soft start setting pin Lock protection and automatic reset circuits incorporated FG output for CJDR1267 RD output for CJDR1267R Thermal shutdown circuit incorporated • • • • • • • • Power 1µF 1kΩ 1kΩ ① ② ③ 100Ω 100Ω RF PART NUMBER CJDR1267 CJDR1267R PACKAGE RFG / RD 10k to 100kΩ 1µF SSOP16 with FG pin VCC FG / RD 5VREG (Rotation speed detection function) SSOP16 with RD pin H (Lock detection function) SENSE IN- ① IN+ ② S-S ③ ④ RMI PWM SSOP16 Package VTH CPWM SGND CT 220pF 30kHz 0.47µF 12V Typical Application Circuit Please carefully read the notice at the end of this data sheet about product use, data sheet changes and important statements. ④ PDF
