Product details

5V rail supervisor with push-pull output

The Texas Instruments TPS3705-50DGNR is a simple reset and power-on reset IC that monitors a single 5V supply rail, asserting an active-low reset when the voltage drops below the 4.55V threshold. It delivers a push-pull output with a 140ms minimum reset timeout, giving the downstream processor time to stabilize after power-up or a brown-out event.

Industrial temperature grade and 8-HVSSOP package

The 8-HVSSOP package with exposed pad helps pull heat from the die into the PCB copper plane — make sure the thermal pad is soldered to a ground plane pour for best thermal and electrical performance.

Frequently asked questions

Can TPS3705-50DGNR be used as a replacement for TPS3705-33DGNR?

No — the TPS3705-50DGNR monitors a 5V rail with a 4.55V threshold, while the TPS3705-33DGNR monitors a 3.3V rail at a different threshold. They are not pin-compatible replacements; choose the variant that matches your supply voltage.
