DRV8860PWPR

Texas Instruments · Stepper Motor Driver · HTSSOP-16-EP

DRV8860PWPR from Texas Instruments, in a HTSSOP-16-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VM power_in Motor power supply; connect to 8-38 V supply bypassed with 0.1 µF ceramic capacitor plus 10 µF electrolytic capacitor to GND; absolute maximum 40 V.
2 DIN input Serial data input from controller; rising edge of CLK clocks data into device; internal 100 kΩ pulldown; VIH min 1.5 V, VIL max 0.7 V.
3 CLK input Serial clock input; rising edge clocks data in for write operations, falling edge clocks data out for read operations; internal 100 kΩ pulldown.
4 LATCH input Serial latch signal; data is latched into the register on the rising edge of LATCH; internal 100 kΩ pulldown.
5 GND power_in Device ground; all GND pins must be connected to ground.
6 DOUT output Serial data output to controller; open-drain output with internal 1.4 kΩ pullup to internal 5.7 V; VOL max 0.5 V at IO = 5 mA.
7 nFAULT output Active-low fault indicator; open-drain output requires external pullup resistor >4.7 kΩ to V3P3; driven low on OCP, OL, OTS, or UVLO fault; IOH leakage max 1 µA at VO = 3.3 V.
8 ENABLE input Output stage enable; logic high enables all eight outputs, logic low disables outputs while allowing serial registers to be read and written; internal 100 kΩ pulldown; VIH min 1.5 V.
9 OUT8 output Low-side NFET output 8; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
10 OUT7 output Low-side NFET output 7; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
11 OUT6 output Low-side NFET output 6; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
12 OUT5 output Low-side NFET output 5; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
13 OUT4 output Low-side NFET output 4; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
14 OUT3 output Low-side NFET output 3; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
15 OUT2 output Low-side NFET output 2; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
16 OUT1 output Low-side NFET output 1; connect external load between this pin and VM; RDS(on) typ 1.5 Ω at IO = 150 mA, TJ = 25 °C; OCP trip level 620 mA; integrated high-side freewheeling diode VF typ 0.9 V.
17 PPAD power_in Exposed PowerPAD thermal pad; must be soldered to PCB ground copper and thermally connected via vias to ground plane for heat dissipation; RθJC(BOTTOM) = 3.0 °C/W for PWP package.
