QHV5160¶
1. Introduction¶
QHV5160 is a upgrade of HV5160, specially designed for high-voltage drive requirements and can work in the voltage range of 8-60V, such as 48V. The new design uses the QFP package of TMC5160, and selects eight 3x3 low-resistance MOSFETs. and also uses Samsung Electronics’ 100V X7R ceramic capacitors

- 900 x 600mil / 22.3 x 15.24mm
- 6 layer TG155 PCB
- 8-60V 3.0A (rms) / 4.2A (peak)【Be constrained by connectors, not components.】
- 8 x NMOS (4.4 mΩ)
- Step/Dir interface & SPI mode default
- Compatible with Stepstick Pins
- Encoder Interface pinout
- DIAG output for sensorless homing
- With thermally conductive silicone and extra strong aluminum heatsink.
3. Application¶
3D printers, CNCs, engraving machines, or other similar devices with stepper motors.

5. Hardware Guide¶
5.1 Pin Functions¶
| Pin | Function |
|---|---|
| Power Supply | |
| GND | Ground |
| VM | Motor Supply Voltage, Provide filtering capacity near pin with short loop to GND plane. Must be tied to the positive bridge supply voltage. |
| VIO | 3.3V to 5V IO supply voltage for all digital pins. |
| Motor Outputs | |
| B1 | Motor Coil 1 |
| B2 | Motor Coil 1 |
| A1 | Motor Coil 2 |
| A2 | Motor Coil 2 |
| Control Inputs | |
| REFL_STEP | STEP input when (SD_MODE=1). or left reference input (for internal ramp generator) |
| REFR_DIR | DIR input (SD_MODE=1). or right reference input (for internal ramp generator) |
| TMC5160 | |
| EN | Enable Motor inputs: GND=on, VIO=off |
| CLK | CLK input. Tie to GND using short wire for internal clock or supply external clock. Internal clock-fail over circuit protects against loss of external clock signal. |
| SDI_CFG1 | SPI data input (SPI_MODE=1) or Configuration input (SPI_MODE=0) or Next address input (NAI) for single wire interface. |
| SCK_CFG2 | SPI serial clock input (SPI_MODE=1) or Configuration input (SPI_MODE=0) |
| CSN_CFG3 | SPI chip select input (negative active) (SPI_MODE=1) or Configuration input (SPI_MODE=0) |
| SDO_CFG0 | SPI data output (tristate) (SPI_MODE=1) or Configuration input (SPI_MODE=0) or Next address output (NAO) for single wire interface. |
| DIAG0 | Diagnostics output DIAG0. Interrupt or STEP output for motion controller (SD_MODE=0, SPI_MODE=1). Use external pullup resistor with 47k or less in open drain mode. Single wire I/O (negative) (only with SD_MODE=0 and SPI_MODE=0) |
| ENC-B ENCB_DCEN_ CFG4 | Encoder B-channel input (when using internal ramp generator) or dcStep enable input (SD_MODE=1, SPI_MODE=1) – leave open or tie to GND for normal operation in this mode (no dcStep). Configuration input (SPI_MODE=0) |
| ENC-A ENCA_DCIN_ CFG5 | Encoder A-channel input (when using internal ramp generator) or dcStep gating input for axis synchronization (SD_MODE=1, SPI_MODE=1) or Configuration input (SPI_MODE=0) |
| ENC-N ENCN_DCO_ CFG6 | Encoder N-channel input (SD_MODE=0) or dcStep ready output (SD_MODE=1). With SD_MODE=0, pull to GND or VCC_IO, if the pin is not used for an encoder. |
5.2 Configuration Instructions¶
Warning
If you use 48V to power the VMOT of the module and 24V step-down to power the VIO, please make sure that 48V and 24V are turned on at the same time (that is, VMOT and VIO arrive at the same time). Otherwise, the drive module may burn out.
5.2.1 Solder Jumper¶
QHV5160 working mode selection is base on the voltage present on Pin21 and Pin22(Integrated pull down resistor). Pin21 is fix to 3.3v(use 1 to represent 3.3v), so working mode is decided by Pin22 only. Pin22 is on the middle pad2 on JP1 below, by default it is connected to pad1, so according to the chart below, the default working mode is SPI Mode. If you want change to Standalone Mode, you need a knife to cut the line(you can't see it, it is under solder mask layer) between pad1 and pad2, and connect pad2 and pad3(solder it).
| Pin22 | Pin21 | Mode |
|---|---|---|
| 0 | 1 | **Standalone Mode，Step-DIR Interface，CFG pins config：**Default Mode，SPI Mode，Step-DIR Interface：The STEP/DIR inputs control the driver the chip is in standalone mode and pins have their CFG functions. |
| 1 | 1 | **（Default）SPI Mode，Step-DIR Interface：**The STEP/DIR inputs control the driver the SPI interface is enabled. Integrated pull down resistor. |
5.2.2 USE SPI mode on FYSETC Boards¶
5.2.3 Heatsink install¶
6. Firmware Guide¶
After you set the working mode according hardware guide section 5.2, you need to do firmware configuration. Follow the instruction below for different firmware Marlin and klipper configuration.
