Table 1 lists the external components.
|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.|
