This part keeps time and calendar data while managing a backup battery or supercapacitor, making it suited for metering, industrial controllers, and embedded systems where a time-stamp must survive a main power loss. The trickle charger is the distinguishing feature here — it lets a small rechargeable coin cell or supercap stay topped off from the main supply, so the RTC section doesn't drain the backup source during normal operation. That saves a separate charger IC and simplifies the BOM for designs that need timekeeping through extended power-down intervals. ## RoHS non-compliant — check your BOM restrictions This part is RoHS non-compliant, which means it contains lead or other restricted substances above the RoHS threshold. If your production line or end-customer requires RoHS compliance (the common case for EU-market consumer goods, medical devices, and most automotive builds), this part will not pass incoming inspection. For legacy designs with a RoHS exemption, or for repair/rework of older boards where the original BOM specified non-RoHS parts, the DS1392U-33 remains a valid drop-in. The lifecycle status is Active, so Maxim is still manufacturing this device — no last-time-buy clock is running. The Active status combined with RoHS non-compliance tells you this part is kept alive for the aftermarket and industrial-repair segment, not for new high-volume consumer designs. ## Sourcing and availability For volume commitments or blanket orders, lead time is established per RFQ.","metaTitle":"DS1392U-33 SPI RTC with Trickle Charger, Active","metaDescription":"Maxim DS1392U-33 SPI real-time clock with battery backup and trickle charger.
