TPS25921ADR is a Hot-Swap Controller device suitable for 48 V DC applications, used in junction boxes that power industrial, automotive and general-purpose systems. It provides actively-controlled power switch with integrated controller/monitor features including programmable overcurrent, overvoltage and overtemperature protection. It is typically used for powered applications or distributed power architectures with centralized point of isolation.
Features of TPS25921ADR:
- Input Voltage Range: 5.5 V to 38 V
- Maximum Output Current: 2.5 A
- Enable Threshold Voltage: 0.1 V
- Output Impedance: 90mΩ
- Open-drain Fault Output
- Programmable Current Limit
- Programmable Overvoltage Protection (OVP)
- Programmable Overtemperature Protection (OTP)
- Programmable Soft-start
TPS25921ADR is mainly used in applications such as pump/fan drive systems, LED lighting, motor control, distributed power architectures, rectifier outputs, junction box outputs, and more. The Hot-Swap controller device provides programmable protection features and integrated current-sense amplifier to monitor the system current accurately, has precision latch off, and protects sensitive loads from burn-out during start-up.
The TPS25921ADR works by exploiting two integrated operational amplifiers and two MOSFETs. One operational amplifier helps to set up the output voltage of the device and other is used for setting up the voltage sense by sampling from the output node of the system. The sampled voltage is then compared with the internal reference and the other comparator pin. Additionally, the two MOSFETs act like a low impedance switch for controlling current or voltage.
The TPS25921ADR is equipped with both overtemperature and overvoltage protection features to ensure safe operation in harsh industrial environments, while the current limit can be calibrated to the application conditions. It provides programmable soft start feature to ensure a smooth current flow when the load is connected.
In summary, TPS25921ADR is a Hot Swap Controller device suitable for 48 V DC applications, mainly used in pump/fan drive systems, LED lighting, motor control and distributed power architectures. It provides actively-controlled power switch with integrated controller/monitor features including programmable overcurrent, overvoltage and overtemperature protection.
