The TPS2490DGSG4 is a latchable positive high-voltage power-limiting Hot Swap Controller 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. It is supported by application notes, an evaluation module and a design tool.
- Programmable power limiting and current limiting for complete SOA protection
- Latched operation
- 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
- Green product and no Sb/Br
