Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | nSLEEP | input | Sleep mode input: logic high enables the device, and logic low enters low-power sleep mode and resets all internal logic, with a 200K internal pull-down to GND. |
| 2 | AOUT1 | output | Connect to motor winding A; the AOUTx absolute maximum voltage is -0.3 to +VIN+1 V. |
| 3 | ASEN | bidirectional | Channel A current sense; connect to the current sensor resistor for Channel A, with sense voltage limited to -0.3 to +0.5 V absolute maximum. |
| 4 | AOUT2 | output | Connect to motor winding A; the AOUTx absolute maximum voltage is -0.3 to +VIN+1 V. |
| 5 | BOUT2 | output | Connect to motor winding B; the BOUTx absolute maximum voltage is -0.3 to +VIN+1 V. |
| 6 | BSEN | bidirectional | Channel B current sense; connect to the current sensor resistor for Channel B, with sense voltage limited to -0.3 to +0.5 V absolute maximum. |
| 7 | BOUT1 | output | Connect to motor winding B; the BOUTx absolute maximum voltage is -0.3 to +VIN+1 V. |
| 8 | FAULT | output | Open-drain fault output that is driven logic low when the device is in an over-temperature fault condition. |
| 9 | BIN1 | input | Bridge B input 1 controls BOUT1, with a 200K internal pull-down resistor to GND. |
| 10 | BIN2 | input | Bridge B input 2 controls BOUT2, with a 200K internal pull-down resistor to GND. |
| 11 | BST | bidirectional | Charge pump output; connect a 10nF to 100nF ceramic capacitor between BST and VIN (absolute maximum VIN+7 V). |
| 12 | VIN | power_in | Power device supply, ranging from 2.7V to 15V; a 10-µF ceramic bypass capacitor to GND is recommended. |
| 13 | GND | power_in | Device ground; both the GND pin and the device PowerPAD must be connected to ground. |
| 14 | VDD | power_out | Internal control and logic supply voltage for internal use only; connect a 2.2µF capacitor from VDD to GND and do not connect any external load to VDD. |
| 15 | AIN2 | input | Bridge A input 2 controls AOUT2, with a 200K internal pull-down resistor to GND. |
| 16 | AIN1 | input | Bridge A input 1 controls AOUT1, with a 200K internal pull-down resistor to GND. |
