34 / 42 page Data Sheet 34 Rev. 1.0 2018-06-14 ITS4130Q-EP-D 130 mΩ Quad Channel Smart High-Side Power Switch Input Pins 8 Input Pins 8.1 Input Circuitry The input circuitry is compatible with 3.3 V and 5 V microcontrollers as well as input levels up to VS 1). The concept of the input pin is to react to voltage thresholds which are referenced to device ground. An implemented Schmitt trigger avoids any undefined state if the voltage on the input pin is slowly increasing or decreasing. The output is either OFF or ON but cannot be in a linear or undefined state. Figure 20 shows the electrical equivalent input circuitry. In case a channel is permanently not needed, the corresponding input pin shall not be left floating but tied with a serial resistor to device ground (not module ground). The recommended value for the serial resistor is 2.2 kΩ. Figure 20 Input Pin Circuitry 8.2 Input Pin Voltage The input pin IN uses a comparator with hysteresis. Switching “ON / OFF” of the channels takes place in a defined region, set by the thresholds VIN(L),max and VIN(H),min. The exact values where the “ON” and “OFF” take 1) VIN must not exceed VS. The relation VIN ≤ VS must always be fulfilled. ITS4130Q-EP-D OUTx INx Device Logic Gate Driver GND Bias ZGND Inv. Comp VS VIH |
