Overvoltage shutdown circuit
WebOvervoltage protection is a power supply feature that clamps the output or shuts down the power supply in higher voltage levels. Often, the voltage level must exceed the preset level for the protection to occur. An over-voltage protection circuit mainly prevents damage to the electronic elements of many power supply devices. Web0. Replace M4 by a Zener Diode (typically 10-15 V depending on Max. gate voltage of Mosfet M3) or use a normal pnp transistor instead of M4 with a …

Webmaster unit shuts down, it programs any slave units to zero output. When a slave unit shuts down, it shuts down only itself, and the master continues to supply output voltage. Battery charging Some power supplies contain an overvoltage protection circuit, which will short the power supply’s output if an overvoltage condition occurs. The OVP ... WebCurrent sharing between the LM340 and Q1 allows the extension of short circuit current limit, safe operating area protection, and (assuming Q1's heat sink has four or more times the capacity of the LM340 head sink) thermal shutdown protection. ISHORT CIRCUIT is approximately 5.5 amp. IOUT MAX at VOUT = 15V is approximately 9.5 amp.
WebApr 4, 2024 · I my understanding of how the zener diode works - zener diode is frankly an open circuit until the zener voltage (with respect to diode's anode) is applied. Then the zener diode starts to conduct in a reverse polarity, so far so good. But the resistor is also needed to limit the current not to fry the diode, absolutely logical...
