LED ring light macro lens battery-powered notches to be able to fix it to a device with rubber bandsClassic mistake: the photomask was flipped, so the SOT23-5 IC also had to be assembled on its back. Macro shot for entertainment purposes:Insights:...
L6924D Battery charger system with integrated power switch for Li-ION/Li-POLYMER Features ■ Fully integrated solution, with a power MOSFET, reverse blocking diode, sense resistor, and thermal protection ■ Ideal for coke and graphite anode single-cell LI-ION packs ■ Both linear and quasi-...
The use of an accessory dead-battery provision (DBP) pin allows for the system to sync a dead battery state in order to enable/disable the BC1.2 detection in the case of an external USB-PHI. The bq24250, bq24251, and bq24257 devices have two modes of operation: 1) I2C™ mode, ...
