LP5813: LP5813 - DSBGA YBH information in datasheet.

I hope pitch is the same for LP5812 (0.4mm)

I will start with this assumption.

Hi Stas,

Please refer the below E2E link to get the package information, thanks!

BR, Jared

Thanks for fast answer.

I was surprised that no info for this package (even pitch) in datasheet.

I have one more question:

In LP5813 datasheet registers are written pretty detailed, but for LP5812 it is just one page with basic description.

Are the drivers for LP5812 the seme for LP5813?

If so what will be behaviour if I write to boost related registers of LP5813 to LP5812?

Stas

Also is dot current (DC) analog setting? I mean it is analog current setup or PWM?

I have application on cell, maximum consumption on board is 5ma, within cell specified maximum current

I don't want to have pulses in 25 mA, it may shorten battery lifetime.

Hi Stas,

Sorry for the inconvenience! It's our mistake that miss the package in the datasheet.

For the register, Yes, LP5813 and LP5812 share the same register, please refer the LP5813 register map.

For the boost related register, if you write it into LP5812. LP5812 will not have any impact since it doesn't have boost module.

Thanks, please also clearify for dot current (DC) settings.

Hi Stas,

Could you please tell me what you don't understand about DC setting?

BR, Jared

Is it true analog setting (where I guarantee maximum current for example 1mA) or it is pwm based?

Hi Stas,

LP581x family has both PWM dimming and analog dimming, so please choose the dimming option as you want.

BR, Jared

That is my question, I want to understand, if dot current is true analog dimming or somehow PWM based?

If I setup dot current 5%, will it be true maximum 1mA output, or it will be PWM on 20mA with 5% duty cycle?

I am asking, because I have cell application with maximum 10mA pulsed specified current from battery. 

I prefer that I can setup driver for true maximum 1mA output for LED.
