Infineon Technologies AUIRS4428S

AUIRS4428S Overview
The specific part being referred to is a PMIC - Gate Drivers chip manufactured by Infineon Technologies. This chip falls under the category of PMIC - Gate Drivers and is specifically designed for automotive applications, meeting the AEC-Q100 standard. The terminal finish of this chip is Matte Tin (Sn) and it has a peak reflow temperature of 260 degrees Celsius. This chip offers two functions and has a supply voltage requirement of 15V. The maximum output current it can handle is 3.3A, while the regular output current is 2.3A. The turn-off delay time for this chip is 70 nanoseconds, indicating the time it takes for the output to fully turn off after receiving the signal. On the other hand, the turn-on time is 0.15 microseconds, which is the time it takes for the output to fully turn on after receiving the signal. The logic voltage levels for this chip are specified as VIL (Low-Level Input Voltage) of 0.8V and VIH (High-Level Input Voltage) of 2.7V. These values determine the voltage thresholds for interpreting the input signals as either low or high logic levels.
