Where can I find Easy Designsim which is described here?
It looks very attractive tool to calculate energy budget. But unfortunately I cannot find it anywhere on cypress.com.
I purchased "S6SAE101A00SA1002 Solar-Powered IoT Device Kit" and evaluating my system but a nice web tool would be a great help.
We know it EOL product. but our customer would like to re-taping.
So we need its datasheet.
Please send us it.

1. S6AL211A94有串口，是不是我可以任意连接具有串口的模块，比如WI-FI, Bluetooth？ 或者可以用电脑的串口助手软件来向S6AL211A94发指令，并接收它的响应？
2. S6AL211A94的串口电压是多少？ 3.3V还是5V? 它内部有个单片机？
3. 在正式画PCB板之前，我试着用了一下S6AL211A94芯片，按照它的规格书，我给它供电、接地，但没有接驱动LED的那些电路：即4路DRV信号，4路调光信号，4路电流反馈信号，4路感温信号这些都悬空的。只是把该供电的，该接地的脚接好了。在此状态下，测48脚输出，规格书说应该有3V直流电压，我用万用表测到1.3V左右，用示波器看到波形的最高处有大约3V，但会掉电，周期性出现。另外，2脚，3脚，46脚都应该是有直流电压，测其波形都不规则，有大波动。 我不知道是因为那些管脚没接导致的这些不正常，还是别的原因。Show Less
My application is almost the design given on page 28 of datasheet, modified as follows:
CIN0 open, INT = AGND, STBY_LDO = VINT, ENA_LDO = VINT.
R1=0, R2=6.8M, R3=10M => VoutH=5.2V VoutL=3.05V
R4=10M, R5=6.2M => VoutLDO=3V
VBAT= 3V, VoutLDO load = 120uA
When VSTORE2 is low enough to switch from VDD to VBAT mode, I can observe an overshoot of 450mV on VoutLDO when Vout2 is switched from VABT to VSTORE1. What is very strange is that the voltage raises for roughly 50us, then decrease to nominal voltage in 8ms. This is much longer than any time constant given by the R and C of the schematic.
When I raise VBAT, I can observe a second overshoot when Vout2 is switched from lower value of VSTORE1 (V=VoutL) to VBAT. The first overshhoot disappears when VBAT is 5.5V. The overshoot value seems dependant on the dV of VIN_LDOShow Less
This is a new design.
I am looking for a PMIC that is able to harvest kinetic power from a 1W dynamo (input source will be from a vehicle's wheel).
It has a Max 25 Vpp and can only output about 300mA.
My objective is to harvest any amount of energy whenever the dynamo is running.
At low speed, it can generate as low as 0.05W and the PMIC has to capture this ultra low power as a storage.
Since it has a high Vpp, a rectification circuit is required and has to step down to 5V (sort of a buck-boost)
The application is to power up a device which has a GPS signal.
I also have a non-rechargeable battery to act as a back up in a form of a switching in case the PMIC fails to work.
If there isn't any reference design for my requirement, is there any other similar PMIC that is used for dynamo/stepper motor etc?
Hope to hear from you soon.
Given in the data sheet:
"When the VDD pin voltage exceeds the OVP detection voltage (VOVPH = 5.4V), an OVP protection current (IOVP) flows from the VDD pin to suppress the rise of the VDD pin voltage and prevent damage to the IC. In addition, when it drops below the OVP release voltage (VOVPL = 5.3V), the flow of OVP protection current is stopped. "
And the electrical characteristics table gives:
"OVP protection current（Iovp）minimum value is 6mA."
If the power source has high impedance and the output is high voltage (hundred volts) and low current (microamps), can the OVP module of S6AE101A work normally and stably for a long time under this condition?
Is there a voltage/current limit range of the input for the OVP part?Show Less
We would like to have QTP report of MB570PF-G-BND-K5ERE1/MB571PF-G-BND-K5ERE1.
We understood those are EOLed devices.
Customer just need this data for internal registration.
Please check and give us some advice.
