Product details

2.25V threshold — which rail it guards

The TPS3836J25DBVT is a single-channel voltage supervisor from TI's TPS3836 family, built to hold a micro-controller or DSP in reset until the monitored supply stabilises. Its 2.25V threshold targets a 2.5V rail — common for DDR memory VDDQ, FPGA core supplies, or low-voltage I/O banks.

Active-low push-pull — no external pull-up needed

The reset output is active-low push-pull, which means it drives both high and low without an external pull-up resistor. This simplifies the board layout and saves a component compared to open-drain supervisors.

Industrial temperature range in a SOT-23-5

The SOT-23-5 package (SC-74A) is a standard footprint shared with many other supervisors, so a PCB layout change is not required if you swap to a pin-compatible sibling in the same family.

Frequently asked questions

Is TPS3836J25DBVT pin compatible with other TPS3836 variants?

Yes. All TPS3836 variants share the same pinout in the SOT-23-5 package. The only difference between order codes is the voltage threshold — for example, the TPS3836J25DBVT monitors a 2.25V threshold, while other suffixes cover 1.8V, 3.0V, or 3.3V rails. The reset output type (push-pull, active-low) and the 10ms timeout are identical across the family.

What is the reset timeout of TPS3836J25DBVT?

The reset timeout is 10ms minimum. After the monitored voltage rises above the 2.25V threshold, the reset output stays asserted for at least 10ms before releasing the processor. This ensures the supply rail has stabilised and the oscillator has started before the CPU begins execution.

Does TPS3836J25DBVT have a push-pull or open-drain output?

The output is push-pull (totem pole), active-low. It drives high when the supply is above the threshold and low during reset, so no external pull-up resistor is required. This differs from open-drain supervisors that need a pull-up to the monitored rail or to the processor's I/O voltage.

Is TPS3836J25DBVT compatible with 3.3V logic?

Yes, the push-pull output drives a CMOS-level high that is compatible with 3.3V logic inputs. The supervisor operates from the monitored rail (2.5V nominal in this case), and its output high voltage tracks the supply, so it meets the VIH threshold of a 3.3V device when the rail is within tolerance. For a direct 3.3V rail, use the TPS3836K33 variant with a 3.07V threshold.
