Pin detailed specifications
Power circuit
Function
The powering circuit provides power to the controller's logic. The KEY input is internally connected with the battery plus terminal via an internal fuse. Power to the internal SMPS is controlled by an electronic switch which is commanded through the POWER input. The controller is turned ON if the voltage on the POWER pin is higher than 8 V and turned off once the voltage is below 0.8 V.
Scheme
Specification
| Number | Name | Function | Operating range | Maximum rating | Protection |
|---|---|---|---|---|---|
| 22 | KEY | power input for control electronics, connected to BATT+ via 3 A fuse | 0 .. Vbat | 0 .. Vbat | one-time fuse |
| 19 | POWER | power control input (switches controller on/off), min. 8 V for on, max. 0.8 V for off | 0 .. 0.8 V; 8 V .. Vbat | 0 .. Vbat | high impedance |
| 21 | POWERGND | power input ground, internally connected to BATT- | 100 mA |
Voltage between 0.8 V and 8 V is not allowed, because the controller is in a non-defined state and could be damaged in such a situation.
Analog inputs
Function
Analog inputs are for processing application analogue signals (e.g. throttle or brake). Reference potential is shared with the main GND (internally connected to BATT-) Operating range is 0 - 5 V.

Optically isolated digital inputs
Function
Digital inputs are for processing application digital signals (e.g. buttons or PPM signals). The operating range is 10 V - 60 V for logic 1 and 0 V - 3 V for logic 0. ODIN+ pin is tolerant to full battery voltage. In the default configuration, they are completely isolated from other controllers' circuits (this is not true if the pull-up or pull-down jumper is used). This input can also measure pulse length (PPM).

|---|---|---|---|---|---|
| 12 | ODIN3+ | positive input of (opto)isolated DIN3 (-> ODIN3) | 0 .. 60 V | 0 .. 80 V, 15mA | galvanic isolation |

Note 1: pulse length measurement range: 800 us - 2200 us for 0 V / 5 V signal, error max. +/-25 us
Note 2: digital input: max. 3 V for LOW, min. 10 V for HIGH
Note 3: when ODIN is configured as floating, it is galvanically isolated from BATT-, from CANGND, COMGND and from the other ODIN input
Note 4: when ODIN is configured as pull-up, ODIN+ is connected internally to GPIO+5V
Note 5: when ODIN is configured as pull-down, ODIN- is connected internally to BATT- (HALLGND, GPIO, POWERGND)
Non-isolated digital inputs
Function
Non-isolated digital inputs are for processing application digital signals (e.g. buttons). These inputs are part of the MSENS circuit and are available only for the MSENS "a" assembly variant. The operating range is 8 V - VBat for logic 1 and 0 V - 3 V for logic 0. DIN inputs are tolerant to full battery voltage. The reference potential is common with the controller's power GND.

Digital open-drain outputs
Function
Digital open-drain outputs, capable of driving an inductive load with a maximum current load capacity of 500 mA. There is no inbuilt overcurrent or overload protection (except the fuse on the KEY pin) and it is necessary to keep the current below the maximal current specifications. Inductive load should be connected between corresponding DOUT+ and DOUT- pins.

Motor position sensor
- Variant - a
Function
Motor position sensor variant "a" can process 3 hall sensors or sin/cos position sensors and 2 inputs that can be used as non-isolated digital inputs (more information about DINs here ).
HALLV/SIN and HALLU/COS inputs have combined functions. These inputs can process digital as well as analogue signals, which means that can be used for sensing two state Halls and also sin and cosine signals. HALLW/COM can be used only for sensing digital signals. All these inputs work in the range from 0 - 5 V. Reference potential is shared with the main GND (internally connected to BATT-).
