Hello,
I hopes to get confirmation of Max Power consumption of Hardware shutdown status which has VBAT connection to VBAT and SW(B4, B5) of TAS2552.
I have tested with TAS2552EVM and found that power consumption is not stable. And the current is changing whenever I do power cycle (Power off/on).
I verified with TAS2552EVM and custom board that Power consumption in Hardware shutdown status (from VBAT, EN=0) with VBAT=3.6V is 0.1uA as described in datasheet. My custom board (portable two way radio) followed reference design of TAS2552EVM, so VAT and SW are connected to Battery directly. I couldn't find power consumption condition for VAT and SW are connected to 3.6V.
I also found that SW ports are connected to Boost Converter in TAS2552 but I can't figure out max current of VBAT and SW in Hardware shutdown status. Please let me know Max power consumption of Hardware shutdown status which has VBAT connection to VBAT and SW(B4, B5) of TAS2552. I think SW needs to be controlled by other power device such as LDO or Load SW, but we don't have much space in PCB, so hopes to get TI's confirmation of Power consumption.
Thanks,
Shaka
