That's the number that matters: most supervisors trip at 2.5V, 3.3V, or 5.0V, but a 4.6V threshold sits right between a nominal 5V rail and its undervoltage lockout. If you're monitoring a 5V supply that must stay above 4.6V before the system is allowed to run, this is the part that keeps the MCU from booting into a brownout. ## Open drain, active low — bench wiring The reset output is open drain, active low. ## Temperature range — indoor and mild environments Rated -40°C to 75°C ambient. ## Package and footprint — SC-74A / SOT-753 Housed in a 5-pin SC-74A (also marked SOT-753). The supplier device package is 5-SSOP. ## Lifecycle — still in active production ROHM lists the BD4746G-TR as Active. No last-time-buy notice, no EOL flag. For the BOM engineer, that means no supply-chain scramble for a drop-in replacement — this part is being manufactured today and will be for the foreseeable future. ROHS3 compliant, so it passes the environmental spec without an exemption.","metaTitle":"ROHM BD4746G-TR Voltage Detector, 4.6V Threshold, Active Low","metaDescription":"ROHM BD4746G-TR voltage detector IC with 4.6V threshold, open-drain active-low reset.
