PWM draws current high.

Other Parts Discussed in Thread: CC2640

Hi,

I am developing with CC2640.

I adopted PWM driver to drive LED in my project.( BLE stack- ble 2.1.1, tirtos-2.13.00.06)

However, when PWM is enabled, there is persistent current draw using PWM driver.

It draws 1.8mA continuously. Is that expected value?

If not, How much can I expect for current draw using PWM?

Thanks,

Hi,

Can you try with the PWM driver in the BLE stack v2.2 release?
C:\TI\tirtos_cc13xx_cc26xx_2_18_00_03\products\tidrivers_cc13xx_cc26xx_2_16_01_13\packages\ti\drivers\pwm

Best wishes

OK, I will try with that driver. By the way, Do you mean using that driver in my current stack V2.1.1? or using BLE stack v2.2 also? As you Know, BLE stack v2.2 is changed many thing. I want to try that simply as far as possible.

Hi Zahid,

I tried with BLE stack v2.2.
In this test, PWM driver draws about 1.20mA. Is that expected value?

If not, please let me know which value I can expect.

Thanks,
