This PCB is an Anti-Spark switch for high capacitive loads (100A, 60V) and was especially designed for electric longboards. It uses 10 TPW1R306PL milliOhm N-MOSFET, which have a Rdson of around 90 uOhm in the worst case, which theoretically enables a maximum current of around 125A with sufficient cooling.
Inspired by the DieBieMS it uses a BQ76200PWR HighSide MOSFET driver, to enable the high switching with NMOS.
The PCB includes the following features:
- dimensions: 74mm x 38.2mm
- maximum current of at least 125A (more with additional copper and cooling)
- maximum voltage of 60V
- controlled dI/dt with capacitor and current limiting resistor
- 10 TPW1R306PL N-channel MOSFET
- BQ76200PWR High Side MOSFET Driver
- A TPS7A4101DGNR 12V 50mA LDO
- A holder for a LittleFuse BF1
- 4 pin JST XH connector for external switch or MCU
- exposed pcb traces to add solder or a copper bar for lower resistance
- V0.1 is the initial version (08.09.19)
- V0.2 uses 10 TPW1R306PL mosfet instead of two IRFS7530 (09.09.19)
