CMD connector
CMD connector is the user side I/O of the driver. This connector contains the control and feedback signals. All signal lines of the port are ESD protected by dedicated suppressors.
Mating connector type is a 10 pin flat ribbon cable connector with 0.1"/2.54 mm pin pitch and a polarity key. See spec sheet of compatible connector here.
CMD pin-out
| Header text | Header text | Header text |
|---|---|---|
| 1 | PULSE | Pulse control. When low, output low current and when high, output setpoint current. |
| 2 | GNDA | Analog ground |
| 3 | IMON+ | Current monitor positive output (differential) |
| 4 | IMON- | Current monitor negative output (differential) |
| 5 | VMON+ | Voltage monitor positive output (differential) |
| 6 | VMON- | Voltage monitor negative output (differential) |
| 7 | ISET+ | Current setpoint positive input (differential) |
| 8 | ISET- | Current setpoint negateive input (differential) |
| 9 | ENABLE | Enable input. When low, output enabled and high or open, output disabled. |
| 10 | GND | Power & digital ground |
Digital signals
All digital signals (PULSE & ENABLE) are referenced to GND and applicable voltage levels are:
| State | Voltage range |
|---|---|
| Logic low | -0.3 .. 0.6V |
| Logic high | 3.0 - 7.0 V |
Differential analog signals
Analog input & output signals support differential signaling to cancel noise and ground loop induced error.
