WebPut the protection diode across the solenoid, cathode to Vcc. Now, if you do this you'll most likely find that it behaves much more as you would expect it to because the MOSFET will turn on properly. You need to maximize gate-source voltage from the Vcc rail to turn it … Web• Pull-up / pull-down / keeper (set by PKE, PUE and PES in IOMUXC) Figure 6. Simplified internal structure of the IOMUX for each pin Pins have a three-state logic. If no device is enabled, then the pins are in high impedance state. It means that the output driver is not controlling the state of a connected circuit. christine hoover msn https://decemchair.com
