Push-pull configuration with TDE1708DFT

The following push-pull driver configuration was designed based on the previous single

driver measurements. In this proposed schematic (see Figure 14) two additional

components (R3, D3) must be added to speed up the turning off of the driver in the low-side

configuration. The resistor R3 creates a weak pull-up while the diode D3 separates the low-

side output from the high-side. The reason for this being that if the low-side driver is forced

high in a short time after turning off then it stays turned on with all the subsequent effects.
