Battery power-up sequencing IC
The MAX4921BETD+ is a battery power-up logic IC from Analog Devices, designed to manage the sequencing and gating of power rails during system startup in battery-powered equipment. This part sits in the Analog & Data Acquisition category, reflecting its role in conditioning and controlling power-up signals before the main data converters or analog front-ends come online.
Package and supply format
Supplied in Bulk packaging — the ICs arrive in a tube or tray, not on tape-and-reel, which suits low-volume prototyping, bench evaluation, or repair stock where a full reel quantity is unnecessary. The Bulk format means the date-code spread is typically narrow for a single production lot, but the buyer should confirm the specific date code range at RFQ if lot-traceability matters for the BOM line.
The part is ROHS3 Compliant, covering the full ten restricted substances including the four phthalates (DEHP, BBP, DBP, DIBP) under EU Directive 2011/65/EU as amended.
