3 / 15 page  3 BCD Semiconductor Manufacturing Limited Preliminary Datasheet ADJUSTABLE-SPEED SINGLE-PHASE FULL-WAVE PRE-DRIVER FOR MOTOR AM4967 Jun. 2008 Rev. 1. 1 Pin Number Pin Name Function 1 OUT2 Second channel P-type driver output. Open-drain output, must be connected with pull-up resistor to drive external power devices in operation 2 OUT2B Second channel N-type driver output. Push-pull output to drive external power devices 3 VCC Power supply 4CS Current limiter indicator. Fixed to 0.2V internally. Maximum allowable cur- rent is decided by external sample resistance. When the voltage of this pin exceeds 0.2V, the output will be shut down by current limit. If this function is not used, connect this pin to ground directly 5VMIN Minimum speed setting terminal. Connect it to VREF when disused. In case it is tied to other power supply for controlling, an isolated resistor is necessary 6VPWM Speed control terminal. It is full speed mode when connected to ground. If the speed is controlled by PWM mode, the frequency of control signal is 20kHz to 100kHz. Moreover, a low pass network is necessary to transfer PWM to DC level 7COSC PWM basic oscillation frequency generator when connected with a capacitor of 220pF. 30kHz frequency is available. 8FG/RD "FG" means pin 8 is an output pin of FG signal which is used for detecting rotation speed. "RD" means pin 8 is an output pin of RD signal, and is used for detecting fan rotate-stop state. "FG" and "RD" can be selected according to the requirement. This pin need to be connected with pull-up resistor when used. A new pulse will be generated once input signal changed. Keep this pin open when it is not to be used 9HIN- Hall sensor negative input. To prevent noise, this pin is recommended to be placed as close as possible to Hall circuit. If necessary, a capacitor may be added between HIN+ and HIN- to reduce the influence caused by noise 10 HIN+ Hall sensor positive input. To avoid noise, this pin is recommended to be placed as close as possible to Hall circuit 11 CT Lock protection and auto start frequency generator. It is connected with an external 0.47 µF capacitor which decides lock-rotate time and start time. If lock-rotate protection function is disused, please connect this pin to GND 12 LS Linear start terminal. This pin is connected to VREF externally via a capacitor of 0.47 µF to 1µF which enables fan start steadily. Start time is dependent to the capacitance. If linear start function is not used, connect this pin to ground 13 VREF 5V voltage reference 14 GND Ground for circuit control 15 OUT1B First channel N-type driver output. Push-pull output to drive external power devices 16 OUT1 First channel P-type driver output. Open-drain output, must be connected with pull-up resistor to drive external power devices in operation Pin Description |
