FT3107T

Fortior Tech · Brushed DC Motor Drivers · TSSOP-20

FT3107T from Fortior Tech, in a TSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VSS power_in Signal and power ground for the controller.
2 VDD5 power_out Digital 5 V LDO output for the digital signal circuitry, specified at 4.9 V to 5.1 V with up to 10 mA output current.
3 TM input Test pin that should be left floating or connected to VDD5.
4 BRAKE input Brake signal input where a low level brakes the motor, with an internal pull-up of 50 kΩ to 150 kΩ (100 kΩ typical).
5 SPEED/PWM input Speed control input accepting either a direct PWM signal (1 kHz to 60 kHz) or an analog voltage in the 0 V to 5.3 V range.
6 FR input Motor rotation direction input.
7 ILIMIT input Current limit analog input, specified for an analog input range of 0 V to 5.3 V when used as the VREF source.
8 FG output Open-drain Frequency Generator speed signal output that requires an external pull-up, with a maximum output current of 10 mA and a maximum withstand voltage of 5.5 V.
9 EMF_W input Phase W back-EMF input that must be proportionately stepped down to less than VDD5 for IC protection.
10 EMF_V input Phase V back-EMF input that must be proportionately stepped down to less than VDD5 for IC protection.
11 EMF_U input Phase U back-EMF input that must be proportionately stepped down to less than VDD5 for IC protection.
12 ISENSE input Current limit and lead angle analog input, where 0 V to 5 V sets a lead angle of 0° to 15°.
13 WL output Low-side phase W NMOS gate driver output, with output high of 8.5 V to 11 V and output low of 0 V to 0.3 V.
14 VL output Low-side phase V NMOS gate driver output, with output high of 8.5 V to 11 V and output low of 0 V to 0.3 V.
15 UL output Low-side phase U NMOS gate driver output, with output high of 8.5 V to 11 V and output low of 0 V to 0.3 V.
16 WH output High-side phase W PMOS driver output, with output high of 11.2 V to 12 V and output low of 3 V to 5 V.
17 VH output High-side phase V PMOS driver output, with output high of 11.2 V to 12 V and output low of 3 V to 5 V.
18 UH output High-side phase U PMOS driver output, with output high of 11.2 V to 12 V and output low of 3 V to 5 V.
19 VREG10 power_out 10 V LDO output, specified at 9.5 V to 10.5 V with up to 10 mA output current.
20 VCC power_in Power supply input, with a recommended range of 3.7 V to 28 V and an absolute maximum of 30 V.
