STPS5H100AF operating temperature?
Regarding the STPS5H100AF, the datasheet states that the storage temperature is -65 to 175°C, but there is no mention of the operating temperature.What is the operating temperature?
Resolved! Misleading statement about TS function of BQ25120A
Hi,Our development board uses BQ25120A for battery management.In the datasheet section 10.2.2.1 Default Settings, there is a statement:• If the function is not needed, connect TS to the center tab of the resistor divider between VIN and the ground.(p...
SPV1050 sample time
The Tsample value doesn't reach the published value (between 0.3 and 0.5 s, and from my measurements between 0.3 and 0.35 s) until Vstore reaches the EOC threshold. Before, it is just around 80 ms. Once EOC is reached and when Vstore decreases again ...
STWBC2-HP and STWLC99 with STSC protocol
I am developing a solution using a STWBC2-HP tx running from a 24VDC supply to drive a STWLC99 rx and need to use the STSC protocol to achieve 50~100W. This is for bespoke power transfer rather than a conventional charger. I am basing the design on t...
