TPS2490
- Programmable Power Limiting and Current Limiting for Complete Safe Operating Area (SOA) Protection
- Wide Operating Range: 9 V to 80 V
- Latched Operation (TPS2490) and Automatic Retry (TPS2491)
- High-Side Drive for Low-RDS(on) External N-channel MOSFET
- Programmable Fault Timer to Protect the MOSFET and Eliminate Nuisance Shutdowns
- Power Good Open-Drain Output for Downstream DC/DC Coordination
- Enable Can Be Used as a Programmable Undervoltage Lockout or Logic Control
- Small, Space-Saving 10-pin VSSOP Package
- Calculator Tool Available (TPS2490/91 Design-in Calculator, SLVC033)
The TPS249x are easy-to-use, positive high voltage, 10-pin Hot Swap Power Manager devices that safely drive an external N-channel MOSFET switch. The power limit and current limit (both are adjustable and independent of each other) ensure that the external MOSFET operates inside a selected safe operating area (SOA) under the harshest operating conditions. Applications include inrush current limiting, electronic circuit breaker protection, controlled load turn-on, interfacing to down-stream DC-to-DC converters, and power feed protection. These devices are available in a small, space-saving 10-pin VSSOP package and significantly reduce the number of external devices, saving precious board space. The TPS249x is supported by application notes, an evaluation module, and a design tool.
