Abstract

The invention discloses an ALD power-on circuit following the AISG-V3 protocol, comprising a current limiting circuit, a current limiting resistor bypass circuit and an opening circuit, the current limiting circuit is a part of the ALD, and the input terminal of the current limiting circuit is connected to The output terminal of the external DC power supply, the output point of the current limiting circuit is connected to the input terminal of the ALD internal power supply module, and the current limiting resistor bypass circuit is arranged on the current limiting circuit for bypassing the current limiting circuit, so The opening circuit is used to open or close the current limiting resistor bypass circuit. The present invention limits the charging current of the energy storage capacitor in the ALD internal power supply module by setting a current limiting circuit, and reaches the specified time of the AISG-V3 protocol, and after the energy storage capacitor is charged, the opening circuit closes the current limiting resistor circuit, the current limiting circuit is invalid, and the ALD enters the normal working state. When the system is powered off, the opening circuit can immediately restore the function of the current limiting circuit, ensuring that the power-on current can still meet the requirements of the AISG-V3 protocol during repeated power-on and power-off processes.

Description

technical field [0001] The invention relates to the technical field of AISG3.0 protocol, in particular to an ALD power-on circuit following the AISG3.0 protocol. Background technique [0002] Such as figure 1 As shown, the AISG3.0 protocol stipulates: (1) From 0.2ms to 50ms after power-on, the peak current consumption of the ALD should be less than or equal to the rated power consumed in the steady-state power mode divided by 30 volts; (2) from Within 50ms to 10s, the peak current consumption of ALD should be less than or equal to the rated power consumed in steady state power mode divided by the actual voltage of ALD. At the moment when the ALD is powered on, a large charging current will be generated due to the need to charge the energy storage capacitor in its internal power module. Therefore, in order to meet the above agreement, how to reduce the peak current limit at the moment of power-on, and cancel the current limit within the specified time, so that the product c...
