4 Key Parameters Design Guide
4.1 Circuit of Input Signals (LIN, HIN)
The input signals can be either TTL- or CMOS-compatible. The logic levels can go
down to 3.3V. The maximum input voltage of the pins is internally clamped to 10.5 V.
However, the recommended voltage range of input voltage is up to 5V. The control pins
LIN and HIN are active low.
They all have an internal pull-up structure with a pull-up resistor value of nominal 75
kΩ. The integrated pull-up resistors are designed to pull up the internal structures, so
that the IC can control CIPOSTM safely. For the more stable operation, an external pull-
up circuit is necessary and recommended value is under 4.7kΩ.
The input noise filter inside CIPOSTM suppresses short pulse and prevents the driven
IGBT from excessive switching loss. The input noise filter time is typically 270ns. This
means that an input signal must stay on its level for this period of time in order that the
state change is processed correctly.
And as shown in Figure 5, R of 100Ω and C of 1nF for the RC filter of interface circuit
is recommended in order to operate safely in harsh environment in terms of EMI. Please
place RC-filter as close to the input pins of CIPOSTM as possible.
