FT3216T

Fortior Tech · Brushed DC Motor Drivers · TSSOP-20

FT3216T 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 RPI input Sets the initial PWM duty cycle for forced-commutation motor start, with duty cycle rising proportionally to RPI voltage over 0 V to VDD5.
2 F/R input Motor rotation direction input, which can be set before power-up or changed during operation (motor brakes, then reverses after FR_DELAY), with digital inputs rated to 5.5 V.
3 RSD input Sets the lock-up protection waiting time Twait, with voltage range 0 V to 5 V as an analog I/O pin.
4 PWM input PWM input for speed adjustment with internal pull-up (150 kΩ to 250 kΩ), logic input withstand 5.5 V, and SREF must be disabled and pulled high when PWM control is used.
5 SREF input Analog input voltage for speed adjustment, where the motor reaches full speed at VDD5 and slows to stop below 0.75 V, and PWM must be disabled and pulled high when SREF control is used.
6 RSF input Sets the start frequency, i.e. the commutation period during forced commutation, with voltage range 0 V to VDD5.
7 SKEW input Sets the soft-start time by limiting PWM duty-cycle slew rate, with a higher SKEW voltage giving a longer startup time, over 0 V to VDD5.
8 VDD5 power_out Digital power output from the internal LDO, regulated to 4.75 V to 5.25 V (5 V typ.) with output current up to 10 mA.
9 SMIN input Sets the minimum speed limit, where PWM is turned off immediately when SREF is below SMIN; it can be pulled low or set by efuse if no minimum speed limit is needed.
10 START input Motor start input, where High starts the motor and Low frees (coasts) it, with internal pull-up (150 kΩ to 250 kΩ) and digital inputs rated to 5.5 V.
11 TMODE input Test signal input that must be connected to GND in application.
12 VCC power_in Power supply input with recommended range 4.5 V to 28 V, absolute maximum 30 V, and built-in UVLO at 3.3 V.
13 MOT_W output Motor phase W output driving the BLDC motor, with high-side Ron of 0.9 Ω max and low-side Ron of 0.7 Ω max at 0.5 A.
14 MOT_V output Motor phase V output driving the BLDC motor, with high-side Ron of 0.9 Ω max and low-side Ron of 0.7 Ω max at 0.5 A.
15 MOT_U output Motor phase U output driving the BLDC motor, with high-side Ron of 0.9 Ω max and low-side Ron of 0.7 Ω max at 0.5 A.
16 RNF input Current-sense input to the current-limit and overcurrent comparator, where the current limit is I = VRNF/RRNF and overcurrent protection triggers above 1.5 A.
17 VSS power_in Signal and power ground for the device.
18 BRAKE input Brake signal input where Low brakes the motor, with internal pull-up and digital inputs rated to 5.5 V.
19 FG output Open-drain frequency generator output giving one pulse per electrical degree by default, with 5.5 V withstand, 10 mA max sink current, and requires an external pull-up resistor.
20 RD output Open-drain rotation detection output that goes high during lock-up protection, with 5.5 V withstand and 10 mA max sink current, and requires an external pull-up resistor.
