Product details

Programmable protection and auto-retry

The controller offers programmable current limit, fault timeout, overvoltage protection (OVP), and turn-on voltage via external resistors and capacitors. Auto-retry after a fault is built in, and an undervoltage lockout (UVLO) threshold is also programmable. These features let the board designer tailor the protection profile to the load without changing the controller — a single BOM line covers multiple card variants by adjusting a few passive values.

It is ROHS3 compliant.

Frequently asked questions

Is TPS24741RGET suitable for 24V systems?

The supply voltage range is 2.5V to 18V, so it is not rated for a 24V nominal rail. For 24V backplanes, look at a controller with a higher maximum input voltage, such as the TPS24750 family.

What is the difference between TPS24741RGET and TPS24740RGET?

Both are single-channel hot swap controllers in the same family. The TPS24741 includes auto-retry after a fault, while the TPS24740 latches off and requires a power cycle or enable toggle to restart. If your application needs automatic recovery after a transient overload, the TPS24741 is the correct choice.

Does TPS24741RGET include an internal MOSFET?

No, the TPS24741RGET does not have an internal switch. An external N-channel MOSFET must be added to the BOM, which allows the designer to select the FET based on the load current and thermal requirements.
