DRV8436PWPR

Texas Instruments · Stepper Motor Driver · HTSSOP-28

DRV8436PWPR from Texas Instruments, in a HTSSOP-28. 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 VCP power_out Charge pump output (VM + 5V) for high-side gate drive; connect 0.22µF 16V X7R capacitor to VM.
2 VM power_in Motor power supply input with range 4.5V to 48V; bypass through 0.01µF ceramic capacitors and bulk capacitor to GND.
3 PGND power_in Power ground internally shorted to pin 12; connect to system ground on PCB.
4 NC unconnected No connection; do not connect this pin.
5 AOUT1 output Winding A motor phase output with maximum 1.1A RMS continuous current.
6 AOUT2 output Winding A motor phase output with maximum 1.1A RMS continuous current.
7 NC unconnected No connection; do not connect this pin.
8 NC unconnected No connection; do not connect this pin.
9 BOUT2 output Winding B motor phase output with maximum 1.1A RMS continuous current.
10 BOUT1 output Winding B motor phase output with maximum 1.1A RMS continuous current.
11 NC unconnected No connection; do not connect this pin.
12 PGND power_in Power ground internally shorted to pin 3; connect to system ground on PCB.
13 VM power_in Motor power supply input with range 4.5V to 48V; bypass through 0.01µF ceramic capacitors and bulk capacitor to GND.
14 GND power_in Device ground; connect to system ground.
15 DVDD power_out Regulated 5V logic power supply output with 2mA maximum load; bypass to GND with 0.47µF to 1µF X7R capacitor rated 6.3V or 10V.
16 nFAULT tri_state Open-drain fault indicator output pulled low on fault condition; requires external pull-up resistor to 3.3V or 5V.
17 VREF power_in Current setting reference input voltage 0.05V to 3.3V maximum for PWM current control.
18 M0 input Microstepping mode setting input with internal pull-down resistor; used with M1 to select stepping resolution from full-step to 1/256 step.
19 TOFF input Four-level PWM off-time input selecting chopping duration of 7µs, 16µs, 24µs, or 32µs during current regulation.
20 DECAY1 input Decay mode selection input with internal pull-down resistor used with DECAY0 to configure current decay mode.
21 DECAY0 input Decay mode selection input with internal pull-down resistor used with DECAY1 to configure current decay mode.
22 M1 input Microstepping mode setting input with internal pull-down resistor; used with M0 to select stepping resolution from full-step to 1/256 step.
23 STEP input Step command input with internal pull-down resistor; rising edge advances indexer one step; maximum frequency 500kHz.
24 DIR input Direction control input with internal pull-down resistor; logic level selects motor stepping direction.
25 ENABLE input Output enable input with internal pull-up to DVDD; logic low disables motor outputs, logic high enables; selects OCP response mode.
26 nSLEEP input Sleep mode control input with internal pull-down resistor; logic high enables device operation, logic low enters low-power 2µA sleep mode.
27 CPL passive Charge pump flying capacitor return node; connect 0.022µF VM-rated X7R ceramic capacitor between CPL and CPH.
28 CPH passive Charge pump switching node; connect 0.022µF VM-rated X7R ceramic capacitor between CPH and CPL for charge pump operation.
29 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
