WebLTC4371 –48V/25A Dual Ideal Diode Controller with Switch "ON" LED Indicator With positive voltage N-channel controllers, the gate drive circuitry often includes an on-chip charge pump with a voltage clamp (the 17V Zener diode) to set the upper gate drive voltage limit as shown below. Webto device. Two Zener diodes are sometimes used in series to prevent leakage current flowing from cathode to anode, which if present causes errors in the current regulation loop. 4 Drawbacks of the Traditional Method The traditional method requires the use of a sense resistor in series with the output in order to sense current.
Web74HC174PW - The 74HC174; 74HCT174 are hex positive edge-triggered D-type flip-flops with individual data inputs (Dn) and outputs (Qn). The common clock (CP) and master reset (MR) inputs load and reset all flip-flops simultaneously.
