Product data sheet
The SE95 is sensitive to power supplies with ramp-up time 2 ms and could NACK or
hang the I
supplies have a >2 ms ramp-up time. If the power supply ramp-up time is 2 ms, use an
RC network with R = 300
the ramp-up time. The 10 F capacitor is the same as the bypass capacitor that is
typically used to prevent fluctuations on the power supply. The 300
the supply voltage by about 45 mV since the SE95 supply current is about 150 A. Ensure
the SE95 is the only device connected to the end of 300
devices would draw more current and cause a larger voltage drop across the resistor.
