Pin Functions
| PIN | I/O(1) | DESCRIPTION | EXTERNAL COMPONENTS OR CONNECTIONS | |
|---|---|---|---|---|
| NAME | NO. | |||
| POWER AND GROUND | ||||
| GND | 1, 12, 13, 24, Thermal pad | — | Device ground | |
| LDOOUT | 15 | — | LDO regulator output | Bypass to GND with a 2.2-μF 6.3-V ceramic capacitor |
| VCC | 18, 19, 20 | — | Device supply | Bypass to GND with 0.1-μF and 10-μF 6.3-V ceramic capacitors |
| VCP | 17 | — | Charge pump | Connect a 0.1-μF 6.3-V ceramic capacitor to VCC |
| CONTROL | ||||
| IN1H | 5 | I | Input 1 HS FET enable | Active high enables HS FET for output 1
Internal pulldown resistor |
| IN1L | 6 | I | Input 1 LS FET enable | Active high enables LS FET for output 1
Internal pulldown resistor |
| IN2H | 7 | I | Input 2 HS FET enable | Active high enables HS FET for output 2
Internal pulldown resistor |
| IN2L | 8 | I | Input 2 LS FET enable | Active high enables LS FET for output 2
Internal pulldown resistor |
| LDOEN | 10 | I | LDO regulator enable | Logic low disables LDO regulator
Logic high enables LDO regulator Internal pulldown resistor |
| LDOFB | 14 | I | LDO regulator feedback | Resistor divider from LDOOUT sets LDO output voltage
May be connected to LDOIN to enable LDO |
| nSLEEP | 9 | I | Sleep mode input | Logic low puts device in low-power sleep mode
Logic high for typical operation Internal pulldown resistor |
| SR | 11 | IO | Slew rate control | Resistor to ground sets output slew rate |
| OUTPUT | ||||
| OUT1 | 2, 3, 4 | O | Output 1 | Connect to motor winding |
| OUT2 | 21, 22, 23 | O | Output 2 | |
| VPROPI | 16 | O | Current sense output | Output current is proportional to H-bridge current. 1 kΩ, 1% resistor to GND for 2-A maximum current with VCC at 2 V. See Equation 1 if more current is required |
(1) Directions: I = input, O = output, OZ = 3-state output, OD = open-drain output, IO = input or output
