Not connected 4 13 FLT2 Overload event diagnostic pin 5 to 20 17 to 24, 35 to 42 OUT Power stage output channel 21 46 FLT1 Over-temperature event diagnostic pin 22 48 IPD Initial current duration / level selector. Connect to GND by a capacitor to set duration of IPKH (see Section 7.3 and Table 9 ). Connect to IN pin by a 220 kΩ resistor to disable initial IPKH threshold (the over-current limit is only IPKL). Connect to GND by a 10 kΩ resistor to disable IPKL (the over-current threshold is only IPKH). Note: Leaving IPD floating is equivalent to a 1 µs duration for IPKH. 23 3 IN Input 24 6 GND Device ground IPS1025HF, IPS1025HFQ Pin connection DS13869 - Rev 3 page 3/32 |
