IWR6843AOP: IWR6843AOP Power block diagram Battery LiSOCl2

Part Number: IWR6843AOP
Other Parts Discussed in Thread: TPS61033

Hi.

I design a PCB where we use the following packs: ER18505H+SPC1550 or ER26500H+SPC1550 (LiSOCl2 with supercapacitor SPC1550) with a IWR6843AOP mmWave Sensor:

The current consumption of the IWR6843AOP mmWave Sensor are:

I choice a boost converter as TPS61033 to step up to 5V and then use the PMIC LP87524J to deliver 1,2V, 1,3V, 1,8V and 3,3V using the pack of battery before mentioned.

1.This combination are the best choice for these purpose or are anothers ic that are better for this?

2. Which QSPI FLASH are the best using this mmWave Sensor? MX25R1635?

Best regards

Hi Blindu,

2. Yes, MX25R1635 is the best QSPI flash using with the mmWave Sensor. It is wide input (1.65V-3.6V) so it can operate at both 1.8V & 3.3V.

For 1. may I know the input voltage to TPS61033.

For the datasheet of TPS61033 I see that and the input voltage of TPS61033 are following packs: ER18505H+SPC1550 or ER26500H+SPC1550 (LiSOCl2 with supercapacitor SPC1550): 2-3.6V.
