Key Document


PMP10748 is a complete automotive front end protection TIDesign that highlights TI's zero IQ Smart Diode Controller and High-Side Protection Controller. This design uses two LM74610-Q1 IC's to drive 40V MOSFETs in OR-ing Configuration for reverse polarity protection. The LM74610-Q1  is highly effective zero IQ replacement of lossy diodes and less effective PFET solutions for revere polarity protection. This design also includes programmable OVP, UVLO and OCP with LM5060-Q1 high side protection controller. This device also provides controlled rise time for safe connection and programmable fault detection delay time with LM5060-Q1

  • Protection from Maximum Reverse Voltage: -45V
  • Fast Response to Dynamic Current Reversal: <5µsec
  • OR-ing Controller
  • Over Current Protection (Programmable): 20A
  • Under Voltage Lockout Option: Programmable
  • Over Voltage Protection (Programmable): 36V
