We can use L200 to send a signal onto a supply line. We can define Vo as Vo = Vref (1+ R2/R1) since the input signal Vi is DC decoupled. The gain of amplified signal is: Gv= -R2/R1 This amplified signal is added to this component. We must impose i1 = i2+i3 (1) by ignoring the current entering pin 4. […]

The MAX6499 comprises undervoltage and overvoltage comparators for window detection. WHen the monitored voltage is within selected “window”, GATE is enhances and the n-channel MOSFET is on. GATE falls to OUTFB when the monitored voltage falls below the lower limit (V triplow) or exceeds the upper limit (Vtriphigh) of the window, turning off the MOSFET. The MAX6499 enabling the DC-DC […]

To protect downstream circuits from overvoltage conditions that show up during load-dump events or transients, we can use the MAX6495–MAX6499/MAX6397/MAX6398 overvoltage protection (OVP) devices. Here’s the circuit diagram: This devices work by controlling an n-channel MOSFET wired in series with the power rail. The gate pulls low and the MOSFET shuts off, disconnecting the power rail when the voltage surpasses […]
