MC3425 over power monitoring circuit, voltage regulator, DC-DC circuit, pin and features of PWU It is the power monitoring circuit with over-voltage and low voltage; in over-voltage detection channel, there is the external SCR output which is used to drive external arc extinction; in the low-voltage detection channel, there is a display with the output voltage failure; the work voltage range is 4.4 ~ 40V; the over-voltage detection driver output current is 300mA, and low voltage display output current is 30mA;the inter includes 2.5V reference voltage, which can do the programming on the hysteresis of input comparator in the low voltage detection channel, and when the temperature is at 70 ℃, the power consumption is 1w.
