Truth Table of Logic Operation
The FAN3225 truth table indicates the operational states
using the dual-input configuration. In a non-inverting
driver configuration, the IN- pin should be a logic LOW
signal. If the IN- pin is connected to logic HIGH, a disable
function is realized, and the driver output remains LOW
regardless of the state of the IN+ pin.
Operational Waveforms
At power-up, the driver output remains LOW until the
V DD voltage reaches the turn-on threshold. The
magnitude of the OUT pulses rises with V DD until
steady-state V DD is reached. The non-inverting
operation illustrated in Figure 52 shows that the output
remains LOW until the UVLO threshold is reached, then

the output is in-phase with the input.
In the non-inverting driver configuration in Figure 50, the
IN- pin is tied to ground and the input signal (PWM) is
applied to IN+ pin. The IN- pin can be connected to logic
HIGH to disable the driver and the output remains LOW,
regardless of the state of the IN+ pin.

For the inverting configuration of Figure 51, startup
waveforms are shown in Figure 53. With IN+ tied to
VDD and the input signal applied to IN–, the OUT

Non-Inverting Configuration
In the inverting driver application in Figure 51, the IN+
pin is tied HIGH. Pulling the IN+ pin to GND forces the
pulses are inverted with respect to the input. At power-
up, the inverted output remains LOW until the V DD
voltage reaches the turn-on threshold, then it follows the
input with inverted phase.
