It integrates multiple voltage rails, sequencing, and housekeeping functions for a mobile handset or portable OMAP-based system. ## Supply range and quiescent current — battery-fit check The input supply range spans 2.7 V to 4.5 V, which directly covers a single-cell Li-ion battery across its full discharge curve (3.0 V to 4.2 V nominal, with headroom at both ends). The 300 µA supply current is the IC's own consumption — the load on the battery from the PMIC itself is under 0.3 mA, leaving nearly all the battery budget for the OMAP core and peripherals. For a design that has already migrated off OMAP, this input range still works with any 3.3 V or 3.6 V regulated rail, but the sequencing and voltage setpoints were tuned for the OMAP power-up protocol. ## Package and temperature — BGA rework and thermal profile The 139-ball NFBGA measures 10 mm x 10 mm. That is a 0.50 mm pitch BGA — the ball diameter and pad size demand a controlled impedance stack-up and a solder mask defined pad on the PCB. For rework, the NFBGA body is thin (nominal 0.8 mm), so the hot-air profile must ramp slowly below 183°C to avoid package cracking from moisture popcorning — bake at 125°C for 24 hours if the floor life has been exceeded.","metaTitle":"TI TPS65920BZCHR Power Management IC, 139-NFBGA, Obsolete","metaDescription":"TI TPS65920BZCHR power management IC for Mobile/OMAP™, 2.7V-4.5V supply, 300µA supply current, -40°C to 85°C, 139-NFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Applications":"Mobile/OMAP™","Mounting Type":"Surface Mount","Package / Case":"139-LFBGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Supply":"300µA","Voltage - Supply":"2.7V ~ 4.5V","Base Product Number":"TPS659","Operating Temperature":"-40°C~85°C","Supplier Device Package":"139-NFBGA (10x10)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/049d824e57f0eb39d1009e9928ea9b74.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65920BZCHR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS65920BZCHR?","answer":"The TPS65920BZCHR was a dedicated companion PMIC for OMAP processors; a direct drop-in replacement does not exist.
