Figure 8 Full Voltage Startup Circuit
.
.
* After power is applied and/or after an inhibit (INH) signal (active low) has been applied and removed, the APTLGF70U120T module requires a forced startup signal between E0-S0, forcing startup under full voltage conditions. The forced startup signal must be a single pulse and cannot be repeated with a frequency greater than 1 kHz. The duration of this pulse must be between 1 & 4sec and must be synchronized with input signal Q being high. The startup timing diagram is shown in figure 9. * The circuit, shown in figure 8 is proposed as an example for generating the startup pulse for inputs E0 and S0. The signal is initiated by the falling edge of a voltage applied to the forced startup signal input. The circuit will synchronize the forced startup signal with Q and forcing the upper switch to turn ON. * The startup signal, between E0-S0, may also be implemented by a negative pulse synchronized with input signal Q being low and forcing the lower switch to turn ON. Examples of both startup sequences being used in the startup of a full - bridge configuration is shown in figure 11.

Figure 10: Inhibit Circuit for APTLGF70U120T * * The APTLGF70U120T modules can be protected against over currents by the inhibit circuit shown above. This circuit can be implemented by one of several functions: - Output current measurement with Hall sensor. - Rectification of the measured value without offset. - Comparison of this value to a reference value (inhibit level fixed by potentiometer). - Memorization of the inhibit order. - Inhibit signal adaption. * When the inhibit order is given, the default is latched and the output of the circuit connected to the INH (pin5) input of the APTLGF70U120T module switches to a low level (the active level for INH). Then the LED (D9) illuminates. * Pushbutton switch (S1) provides a source for the re-initialization of the Inhibit circuit.
