Power Management

Hi ,

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.

Thanks!

Regarding MB88346BPF-G-BND-EFE1,

We know it EOL product. but our customer would like to re-taping.

So we need its datasheet.

Please send us it.

Best regards.

Hello,

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.

Thank you.

Regards

Dawson

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?

S6ASE101Aの評価ボードを検討しております。

VOUTLの設定電圧について質問です。

評価ボードを測定したところ、VSTOREが2.5Vに低下すると、VOUTがOFFします。

VOUTLの設定は1.9Vです。
