# PowerBoard (Component) ## Description Use this template if you're planning to get your 1 to 2-layer board manufactured in JLCPCB. It has the via min/max and trace width constraints already baked as global rules. #project-template #template #manufacturer-design-rules ## Component Details - **Owner:** spurgazr - **Created:** 10/14/2024 - **Last Updated:** 10/19/2024 - **Visibility:** Public - **Relay for 12V solenoid:** We have relay that will control 12V solenoidV - **Charger IC:** 12V charger IC that use PD power delivery circuit that have selected option with combination of resistors for charging 3S battery with 12V 3A = 36W PD charging circuitV - **Battery Protection BMS:** We need to have bms battery protection circuit for overcharge and overdischarge and short circuit - ** Buck Converter Circuit:** LM2596 - **Buck Converter circuit:** We need to use that 12V from solenoid power, and buck step down to 5V fixed for powering MCU, so we need to use buck converter circuit for step down from 12V to 5V - ** Boost Converter Circuit:** TPS61022 - **Boost Converter:** We need boost converter circuit for Input from 9-12V and output fixed stable 12V 1A for powering solenoid for smart door lockV - **USB-PD Charging Circuit:** BQ25713 - **BMS:** BQ77915V - **Mount Type:** PCB - **Package / Case Code:** TO --- *Generated from [https://www.flux.ai/spurgazr/powerboard~5y](https://www.flux.ai/spurgazr/powerboard~5y)*
