PRODUCTION DATA.
Table 1 lists the external components.
| PIN | DESCRIPTION | ||
|---|---|---|---|
| NAME | NO. | ||
| LDOFB | 14 | LDO regulator feedback | Resistor divider from LDOUT sets LDO output voltage. |
| LDOOUT | 15 | LDO regulator output | Bypass to GND with a 2.2-μF 6.3-V ceramic capacitor. |
| SR | 11 | Slew rate control | Resistor to ground sets output slew rate GND to 2.4 MΩ. |
| 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 |
| VPROPI | 16 | Current sense output | Output current is proportional to H-bridge current. 1 kΩ, 1% resistor to GND for 2-A max current with VCC at 2 V. See Equation 1 for if more current is required. |
