The Commander SE has the following voltage thresholds: Application Note CTAN 173. The Application Note is pertinent to the Unidrive Commander SE Families. Unidrive Size 1 2 Operating on DC Supplies. What I need is a single supply Op Amp, capable of operating at 5V, and able to Follow a voltage from gnd to 5V. Looking at the TLC2272 datasheet - its noted the recommended operating condition is to VDD - 1.5V (so I can only expect an input of 3.5 at the output in voltage follower mode)? This application note describes a universal ultra wide input voltage range power supply module.From now the voltage follower Q1 starts working and stops further increasing of the voltage across IC1. So any additional voltage increases across Q1 until its maximum value. This application note supplements the DA9063 datasheet with further detail of the monitoring feature for the input voltage (VSYS) and output voltages (LDOs, bucks), and also describes manual monitoring of rails. Note that this slope may either be added to the current waveform, or subtracted from the error voltage.Refer to equation 13. 3-45.
