Notes: 1. Voltages are referenced to anode.

2. The PS pin is only provided by the HA17431VLP.

3. The PS pin voltage must not fall below the cathode voltage. If the PS pin is not used, the PS pin

is recommended to be connected with the cathode.

4. Ta

≤ 25°C. If Ta > 25°C, derate by 1.2 mW/°C.

5. Ta

≤ 25°C. If Ta > 25°C, derate by 4.0 mW/°C.

6. Ta

≤ 25°C. If Ta > 25°C, derate by 6.4 mW/°C.
