It's precise and • Programmable Protection Settings: programmable protection settings aid in the design of – Current Limit: ±5% at 10mV high power, high availability systems where isolating faults is critical. – Fast Trip: ±10% at 20mV – Reverse Voltage: ±1mV at –1 mV Programmable current limit, fast shut down, and fault timer protect the load and supply during fault • Programable Response Time for Fast Trip and conditions such as a hot - short. The fast shutdown Reverse Voltage threshold and response time can be tuned to ensure • Programmable FET SOA Protection a fast response to real faults, while avoiding nuisance • Dual Timer (Inrush/Fault) trips. Programmable SOA (Safe Operating Area) protection and the inrush timer keep the MOSFET • Interchangeable Hot Swap and ORing safe under all operating conditions. After asserting a • Analog Current Monitor (1% at 25mV) power good, TPS2474x runs the fault timer during • Status Flags for Faults and Power Good over-current events, but doesn't current limit. It shuts down after the fault timer expires. Two independent • UV and OV Protection timers (inrush/fault) allow the user to customize • Independent EN for Hot Swap and ORing protection based on system requirements. The ORing • 4mm × 4mm 24-pin QFN function of the TPS2474x allows the user to program • 40 = Latch, 41 = Retry, 42 = Fast Latch Off the reverse voltage threshold and response time to aid in the design of redundant power supply systems. 2 Applications Device Information(1) • Enterprise Storage PART NUMBER PACKAGE BODY SIZE (NOM) • Power Muxing TPS24740 • Redundant Power Supplies TPS24741 VQFN (24) 4.00 mm x 4.00 mm TPS24742 • Battery Back Up (1) For all available packages, see the orderable addendum at the end of the data sheet. 4 Simplified Schematics sp TPS2474x in Priority Muxing 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
