The device can limit the current drawn from its supply, so that it can be used with batteries that do not support high peak currents. The input current limit is active during normal operation and at start-up to avoid high inrush current. The device has eight current limit settings:

• 1 mA
• 2.5 mA
• 5 mA
• 10 mA
• 25 mA
• 50 mA
• 100 mA
• Unlimited

CFG1 and CFG2 pins select which setting is active (see Section 6.3.6).
