The reset output is active high with a push-pull, totem-pole stage — no external pull-up resistor needed. ## 2.6 V threshold — matching the supervisor to the core supply The 2.6 V threshold sits between the 2.5 V and 3.3 V logic supply families. It is a good fit for monitoring a 3.3 V rail where the supervisor must assert reset before the downstream MCU or SoC enters an undefined state — typically before the supply drops below the processor's minimum operating voltage. For a 2.5 V core rail, the threshold is too high and would cause nuisance resets; the BU4921G-TR with a lower threshold is the correct choice there. ## Active high reset — verify polarity before layout The BU4926G-TR asserts a logic high on the reset output when the monitored voltage falls below 2.6 V. Many MCUs and SoCs expect an active low reset (RESET#). If your processor requires a low-going signal, an external inverter or a different supervisor variant (such as the BD4929G-TR with active low output) is needed. Check the processor reset pin polarity before committing the BOM. ## Package and footprint: SC-74A / SOT-753 The supplier device package is 5-SSOP. It is a small surface-mount footprint suitable for space-constrained PCBs. ## Lifecycle and sourcing ROHS3 compliant.","metaTitle":"BU4926G-TR Simple Reset/Power-On Reset, 2.6V Threshold","metaDescription":"ROHM BU4926G-TR simple reset supervisor, 2.6V threshold, active high push-pull output, -40°C to 125°C, SC-74A.
