Product details

1.2V threshold supervisor – core-rail watchdog

The TPS3850G12DRCT is a single-channel voltage supervisor with a fixed 1.2V threshold, making it a direct fit for monitoring low-voltage core rails in MCUs, FPGAs, or SoCs where a dip below 1.2V must trigger a clean reset. The reset output is Active Low, open-drain, so it can be wire-ORed with other reset sources on the same pull-up rail — common in multi-rail systems where a single fault pulls the whole system into reset.

125°C junction – industrial and automotive margin

The reset timeout is adjustable/selectable, letting the designer match the power-up settling time of the downstream load — a 100 ms timeout might work for a flash-based MCU, but a larger FPGA may need a longer delay programmed via an external capacitor.

Frequently asked questions

Is TPS3850G12DRCT active high or active low?

Active Low. The reset output goes low when the supply drops below the threshold and remains low until the supply recovers and the timeout expires.

What is the reset timeout range for TPS3850G12DRCT?

The reset timeout is adjustable/selectable, meaning the designer can set the delay with an external capacitor. The exact range depends on the capacitor value; the datasheet provides the formula.
