L6235D

STMicroelectronics · Motor Driver ICs · SO-24-300mil

L6235D from STMicroelectronics, in a SO-24-300mil. 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 H1 input Single ended hall effect sensor input 1.
2 DIAG output Open drain output that pulls to GND when an overcurrent on one of the high-side MOSFETs is detected or during thermal protection.
3 SENSEA power_in Half-bridge 1 and half-bridge 2 source pin; must be connected together with pin SENSEB to power ground through a sensing power resistor.
4 RCOFF passive RC network pin; a parallel RC network connected between this pin and ground sets the current controller OFF-time.
5 OUT1 output Power output 1.
6 GND power_in Ground terminal; on SO24 packages used for heat dissipation toward the PCB.
7 GND power_in Ground terminal; on SO24 packages used for heat dissipation toward the PCB.
8 TACHO output Frequency-to-voltage open drain output; every pulse from pin H1 is shaped as a fixed and adjustable length pulse.
9 RCPULSE passive RC network pin; a parallel RC network connected between this pin and ground sets the duration of the monostable pulse used for the frequency-to-voltage converter.
10 SENSEB power_in Half-bridge 3 source pin; must be connected together with pin SENSEA to power ground through a sensing power resistor; inverting input of sense comparator is connected at this pin.
11 FWD/REV input Logic input that selects the direction of rotation; HIGH level sets forward operation, LOW level sets reverse operation; if not used must be connected to GND or +5 V.
12 EN input Chip enable logic input; LOW level switches OFF all power MOSFETs; if not used must be connected to +5 V.
13 VREF power_in Current controller reference voltage logic input; do not leave this pin open or connect to GND.
14 BRAKE input Brake input logic pin; LOW level switches ON all high-side Power MOSFETs implementing the brake function; if not used must be connected to +5 V.
15 VBOOT power_in Bootstrap supply voltage needed for driving the upper Power MOSFETs.
16 OUT3 output Power output 3.
17 VSB power_in Half-bridge 3 power supply voltage; must be connected to the supply voltage together with pin VSA.
18 GND power_in Ground terminal; on SO24 packages used for heat dissipation toward the PCB.
19 GND power_in Ground terminal; on SO24 packages used for heat dissipation toward the PCB.
20 VSA power_in Half-bridge 1 and half-bridge 2 power supply voltage; must be connected to the supply voltage together with pin VSB.
21 OUT2 output Power output 2.
22 VCP output Charge pump oscillator output.
23 H2 input Single ended hall effect sensor input 2.
24 H3 input Single ended hall effect sensor input 3.

CAD (KiCad official)

  • Symbol: L6235D
  • Footprint: Package_SO:SO-24_5.3x15mm_P1.27mm
  • 3D model: SO-24-300mil, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.75 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: l6235d-etched.step / l6235d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l6235d.step / l6235d.glb are the bare package body.
