PT2513

PTC(Princeton Tech) · Motor Driver ICs · HTSSOP-16-EP

PT2513 from PTC(Princeton Tech), in a HTSSOP-16-EP. 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 VO output V-phase motor output; absolute maximum output pin current is 1.0 A (UO, VO, WO pins).
2 UO output U-phase motor output; absolute maximum output pin current is 1.0 A (UO, VO, WO pins).
3 RF input Current sense input: connect a resistor to ground for current limit or overcurrent detection, with PWM duty reduced when RF exceeds 0.3V (Vrf 0.25 to 0.35V, OCP reference 0.5V).
4 SEL input FG output select: FG output when open, at VREG or grounded, or 1/2FG output at 1/2 VREG; grounding also selects six-window ZC detection.
5 FWR input Forward/reverse direction setting (called FR in the function description); changing it during operation stops the motor and then reverses it.
6 FG output FG speed signal output, open-drain with pull-up up to VDD, low level 0.15V typ at 5mA.
7 MIN input Minimum duty cycle setting with operating range 0.5V to 3.0V; tied high (VREG) it is disabled.
8 MAX input Maximum duty cycle setting with operating range 0.5V to 3.0V; tied high (VREG) it is disabled.
9 GND power_in System ground.
10 VREG power_out Internal 5V regulator output (4.5 to 5.5V) requiring an external stabilizing capacitor (1uF in the application circuit).
11 COM input Motor virtual common (neutral) point used as back-EMF comparison reference; ZC filter capacitor between COM and FLT is 100pF to 10nF.
12 FLT input Back-EMF signal filter input; ZC filter capacitor between COM and FLT is 100pF to 10nF.
13 OSC passive Start-up step and acceleration adjustment capacitor pin, with capacitor about 100pF to 10nF (charge/discharge current 5.6uA).
14 VSP input Speed control command input accepting DC (0.3 to 3.0V) or PWM (1 to 25kHz); runs at maximum when left open.
15 VDD power_in Power supply input, operating range 6V to 16V (absolute maximum 20V).
16 WO output W-phase motor output; absolute maximum output pin current is 1.0 A (UO, VO, WO pins).
17 Heatsink passive Back-side thermal pad (heatsink); datasheet lists it as a power pin without specifying the connection.
