4 External Components
4.1 Gate Driver Charge Pump (TMC6130)
For the external N-channel power MOSFET bridge, TMCC160 generates a 12V gate source voltage
for high and low side MOSFETs (N-channel). The gate source voltage will also be maintained if the
supply voltage falls below 12V. External component example is shown in schematic below. Buffer
capacitor for charge pump linear regulator (C3) should not be smaller than 4.7µF.
If the supply voltage does not fall below 12V charge pump circuitry can be left away without
performance loss (connect VCP to VM, omit D1, D2, C2, VCP_SW not connected).
