LT1166控制的功率级偏压,在工作时比如上管5A电流,下管是否会截至或者下管还是在LT1166设定的静态电流下。

    The output devices will both be at quiescent setting when not delivering current to the load, but as one device delivers load current, the other device will be controlled to a lower current than quiescent, but not to zero current. If quiescent was set to 100mA for example, the lower current device might go as low as around 30mA perhaps. There is an LTspice model of the LT1166 to investigate the action, but of course models are never perfect in all respects.
