LP5009: Inquiry on the state of LEDx pins in LP5009 when EN pin is LOW

Yangqi Guo

Part Number: LP5009

Tool/software:

Hi, could you help to confirm the state of LEDx pins in LP5009 when EN pin is LOW? That is, what would be the measured resistance from LEDx pins to GND pin, when EN pin is LOW?

Hi Yangqi,

Yes, when the EN is pulled down the LP5009 enters shutdown mode, all the outputs should stay in high impedance state.

Best regards,

Felix

Hi, it will be used in a sports equipment used for golf, where LP5009 is used to control RGB indicators. The project is still at prototyping stage, I don't have the schedule.
