current 2.2mA when sleep,what't wrong?

[wuvo.leo]

Hi,all.i call function "sd_clock_hfclk_release(); power_manage();" and want my device to sleep.as this,my device's current is 2.2mA.what's wrong ?Can someone help me?

I guess.

1. Be careful circuit design When the voltage divider or to supply power to the resistor, the current consumed naturally.

2. You can wake up unwanted. There also may be waking from Sleep Mode by LPC.

I hope solved well.

Ensure that you don't have any peripheral enabled like enabled RX in UART, TIMER enabled, GPIOTE task/event enabled etc. any peripheral that requires HF clock will prevent system from shutting it down.

Yes,i enabled UART for DTM,enabled PWM(used timer 2).i initialize these peripheral and then sleep. need to disable them before sleep?Thanks a lot !
