14. PPTC Fuse for DC Motor Stall Protection

Neha is designing a 12V DC motor controller for automated equipment. 

The motor draws 1.5A during normal operation but can draw 5A or more if the motor stalls due to a mechanical jam. 

To protect the motor driver from sustained overcurrent during stall, she needs a through-hole PTC resettable fuse in series with the motor supply. 

The fuse must hold above normal motor current with margin for thermal derating in a warm enclosure, and trip on stall current, then reset automatically when the jam is cleared. 

The company's AVL specifies Littelfuse, so the part must be selected from Littelfuse on DigiKey. 

Help her select a suitable PTC resettable fuse from Littelfuse on DigiKey.
