6 / 8 page 點晶科技股份有限公司 SILICON TOUCH TECHNOLOGY INC. ST1111J SP-ST1111J-A.005 Version :A.005 Page :5 Application Notes The capacitor COUT between output nodes is required for high current application. The capacitor COUT is dependent on coil load and external PWM frequency. The recommended capacitor COUT is about 0.1μF for external PWM frequency larger than 20KHz and about 1μF for external PWM frequency less than 2KHz. The output driver node O1/O2 will be “turned to sink/drive” for V(HIN) = logic low. Similarly, the output O1/O2 will be “turned to drive/sink” for V(HIN) = logic high . The FG pin is an open-drained output and the output frequency is dependent on the logical voltage of FGS pin. The output frequency is the same with HIN input signal when V(FGS) is logical low and 1/2 HIN frequency when V(FGS) is logical high. If there is no need for FG output, let FG output pin open. The pull-up resistors are built-in at pins HIN, PWM and FGS. For multiple usage of PCB, connecting 0Ω resistor between the FGS pin and GND will select FG output function or floating 0Ω resistor will select FG/2 function. There is no need of external timing capacitor for lock protection and auto-restart function. For 5V application, the drivers will be shut down roughly 1 to 3 seconds after the motor is locked. When the drivers have been shut down, the automatic self-restart circuit will try to power up the drivers every 1 to 3 seconds until lock is released. The power polarity reverse protection circuit is built-in. The external protection diode for power reverse fault is no need. There is no requirement of the bypass capacitor or Zener Diode between VDD and GND in normal applications. The connection of this capacitor or Zener Diode between VDD and GND will reduce noise effect and increase stability of operation, if required. |
