摘要： A level shift circuit in accordance with the present application seeks to meet the need of high voltage level shift signaling with minimum delay and power dissipation by using parasitic emulation, blocking of signaling during times of common mode noise, and mismatch filtering to enhance operation robustness to circuit mismatch and delay. A dv/dt sensing circuit is provided to detect any slew in offset between negative supply voltages and ground in a circuit. This detection is used to control a noise canceling circuit to ensure that noise that results from that offset is not propagated to the output of the level shift circuit. A parasitic emulator is preferably used to provide dv/dt sensing. The output of the parasitic emulator is used to activate a noise canceling circuit to prevent noise from reaching the output terminal of the level shift circuit.

摘要翻译： 根据本申请的电平移位电路旨在通过使用寄生仿真，在共模噪声期间阻塞信令以及不匹配滤波来满足具有最小延迟和功率耗散的高电压电平移位信令的需要，并且提高了操作的鲁棒性 电路不匹配和延迟。 提供dv / dt感测电路以检测电路中的负电源电压和接地之间的任何摆幅偏移。 该检测用于控制噪声消除电路，以确保由该偏移产生的噪声不会传播到电平移位电路的输出。 优选地使用寄生仿真器来提供dv / dt感测。 寄生仿真器的输出用于激活噪声消除电路，以防止噪声到达电平移位电路的输出端。

摘要： An over temperature detector circuit for use in a switching converter including one or more power switches in accordance with an embodiment of the present application includes a silent sense generator connected to at least one power switch and operable to detect a noise level of the switch and to provide a generator output signal indicative of absence of switching noise and a comparator operable to compare a temperature sensor signal from a temperature sensor with a reference voltage to provide an alarm signal indicating an over temperature condition when the temperature sensor signal exceeds the reference voltage, wherein the alarm signal does not indicate an over temperature condition when the generator output signal does not indicate absence of switching noise
