The Texas Instruments TPS24742RGER is an integrated Hot Swap and ORing controller suitable for 2.5V to 18V systems. It provides precise and programmable protection settings, crucial for high power and high availability systems where fault isolation is critical.
Key features include programmable current limit with ±5% tolerance at 10mV, a fast trip threshold with ±10% tolerance at 20mV, and reverse voltage protection with ±1mV tolerance at -1mV. The device also offers programmable response times for fast trip and reverse voltage, programmable FET SOA protection, and a dual timer for inrush and fault conditions. An analog current monitor provides a 1% tolerance at 25mV.
This controller supports interchangeable Hot Swap and ORing functions, with independent EN pins for each. It includes status flags for faults and power good indication, along with undervoltage (UV) and overvoltage (OV) protection. The TPS24742RGER is housed in a 24-VQFN (4x4) package and is designed for surface mount.
Its programmable protection settings aid in designing robust systems that protect the load and supply during fault conditions like hot-shorts. The fast shutdown threshold and response time can be tuned to ensure rapid response to real faults while preventing nuisance trips. Programmable SOA protection and the inrush timer ensure MOSFET safety under all operating conditions.
