TPS2491DGSR 9V–80V Power-Limiting Hot Swap Controller
The TPS2491DGSR is a high-voltage, power-limiting hot swap controller from Texas Instruments, designed for safe insertion and removal of live circuit cards in 9V to 80V systems, housed in a compact 10-pin VSSOP (DGS) package for space-constrained SMT designs. This chip integrates a high-side gate driver for an external N-channel MOSFET, independent programmable current and power limiting, and an automatic retry fault response, ensuring the MOSFET operates within its safe operating area (SOA) during inrush, overload, or short-circuit events. It supports industrial-grade operation from -40°C to +85°C, features a 100V absolute maximum rating for transient protection, and includes a power-good open-drain output for downstream DC/DC converter coordination, making it ideal for rugged, high-reliability power management applications.
Selection Advantages
Choosing the TPS2491DGSR delivers unmatched performance, flexibility, and reliability for high-voltage hot swap designs: its 9V–80V wide input range and 100V transient rating cover most industrial and telecom high-voltage systems, reducing the need for multiple controller variants. Independent current and power limiting provides precise MOSFET protection, extending device lifespan and enhancing system reliability. The compact VSSOP-10 package saves valuable PCB space in densely populated industrial and telecom boards. Texas Instruments' rigorous AEC-Q100 and RoHS compliance ensure quality and sustainability for mass production. Comprehensive design resources, including evaluation modules and design calculators, accelerate prototyping and time-to-market. And automatic retry functionality minimizes system downtime by recovering from transient faults without manual intervention.
Alternative power-limiting controllers
LM5069: A 100V hot swap controller with similar SOA protection and latched fault operation, suitable for high-voltage industrial and telecom applications.
MIC2040-1YMM: A Microchip 5.5V high-side power switch with adjustable current limiting, ideal for low-voltage USB and industrial load control.
TPS2490DGSR: A pin-compatible latched-operation variant of TPS2491DGSR, offering fault latching for systems requiring manual reset after faults.
ADM1270ARQZ-R7: A 80V hot swap controller with integrated current sensing and power-good output, optimized for telecom and data center power systems.
