SKYPER™ 32PRO -
characteristic or hiccup-mode can create problems if no sufficient over current margin is available. The voltage
has to rise continuously and without any plateau formation as shown in the following diagram.
If the power supply is able to provide a higher current, a peak current will flow in the first instant to charge up the
input capacitances on the driver. Its peak current value will be limited by the power supply and the effective
impedances (e.g. distribution lines), only.
It is recommended to avoid the paralleling of several customer side power supply units. Their different set current
limitations may lead to dips in the supply voltage.
The driver is ready for operation typically 150ms after turning on the supply voltage. The driver error signal
PRIM_HOLD_OUT and PRIM_HOLD_IN are operational after this time. Without any error present, the
PRIM_HOLD_OUT signal will be reset.
To assure a high level of system safety the TOP and BOT signal inputs should stay in a defined state (OFF state,
LOW) during driver turn-on time. Only after the end of the power-on-reset, IGBT switching operation shall be
permitted.
Under Voltage Reset (UVR)
The Under Voltage Reset circuit configures the driver core to hold in a reset state during power on and power off.
UVR can be thought of as a supplement function to the build in power-on-reset by the user. While in reset, the
driver is held in its initial condition until PRIM_nPWRFAIL_IN is forced into HIGH state. Once the system reset
sequence completes, the driver core is ready to operate.

Please note:
Do not use PRIM_nPWRFAIL_IN to place the driver core into halt mode during operation.
