TI中文支持网hi，
用DRV103H做驱动电路，按照datasheet上的要求 手工焊接了一个boom。pin1接30k电阻，测得电压为2.29V，pin2 为NC 电压为0；pin3接47K电阻，测得电压为1.24V；pin4为GND（图中没画）；pin7为NC；pin6接24V，现在出现的现象是：pin8=GND时，pin5-pin6之间会输出50HZ的pwm。pin8=5V时，一直为24V。片子是TI申请的样片。
期待大牛解答！

Pin 8 Input
The input is compatible with standard TTL levels. The device output becomes enabled when the input voltage is driven above the typical switching threshold, 1.7V. Below this level, the output is disabled. Input current is typically 10nA when driven HIGH and 10nA with the input LOW. The input should not be directly connected to the power supply (VS) or damage will occur.
你的结果跟手册的说法对不上哪
