Note:

5. For improved accuracy LED current should be greater than 60mA.

6. Maximum LED current is also limited by ambient temperature and power dissipation such that junction temperature should be kept less than or equal

to +150°C.

7. All voltages unless otherwise stated are measured with respect to OUT pin.

8. Measured by the percentage of LED current variation when VINOUT varies from 3.5V to 60V.

9. Subject to maximum junction temperature of +150°C not being exceeded. The Maximum ambient temperature range is limited by device power

dissipation; such that its junction temperature should be kept less than or equal to +150°C. See Page 3 for more information on power dissipation.

Devices have been qualified to AEC-Q100 Grade 2.

10. Apply the power linearly to the chip until the device starts to turn on.

11. tON_MIN time includes the delay and the rise time needed for IOUT to reach 90% of its final value. tOFF_MIN time is the time needed for IOUT to drop

below 10% of its final value.

12. This parameter only guaranteed by design, not tested in production.

13. Ambient temperature at which OTP is triggered may vary depending on application, PCB layout and material used.
