NOTES:

1. For Open-Load Detection, the HIP0082 has an internal series pullup resistor, ROL and diode, DOL connected from OUTx to VCC.

2. HIP0084 OL (Open-Load) Detection:

Case 1: For OL Detection, an external series resistor and diode pullup connected from OUTx to VCC is needed.

Case 2: If no failure distinction for OL or SG (Short-to-GND) is required, both faults may be detected (without distinction), with an external

pulldown resistor.

For either case, the pullup or pulldown resistors should be typically 10k

Ω or greater.
