MC13892DJVKR2 Descripción general
A power management IC (PMIC) is a specialized power management integrated circuit that consolidates multiple voltage regulators, power switches, chargers, and supervisory functions into a single die. In the power-management hierarchy, a PMIC sits above individual LDOs and DC-DC converters, acting as the system-level power hub that sequences, regulates, and monitors all rails required by an application processor and its peripherals.
Key features of the MC13892DJVKR2 include four adjustable synchronous buck regulators for core and I/O rails, twelve adjustable low-dropout regulators for analog, audio, and peripheral supplies, an integrated 10-bit ADC for battery and thermistor monitoring, battery charging management, LED display drivers, and coin cell backup support - making it a complete power subsystem for handheld and mobile devices.
Architecturally, the MC13892 integrates power sequencing logic tailored to i.MX processors, ensuring core rails power up in the correct order with proper reset supervision. The multi-regulator topology reduces external component count, board area, and bill-of-material cost compared with a discrete multi-regulator design, while the 139-ball square TFBGA footprint concentrates all power functions in a compact 7x7 mm area. The industrial temperature grade supports demanding portable environments.
Typical applications include personal media players based on the i.MX51 or i.MX37, PND (personal navigation device) platforms using i.MX35, and industrial handheld terminals built on i.MX27. The battery charger function and LED drivers make it especially suitable for battery-powered portable multimedia equipment.
A key design consideration: because the MC13892 is a processor-specific PMIC, the power-up sequencing and regulator configuration are tightly coupled to the i.MX boot flow - always verify rail order against the i.MX reference design and program configuration fuses/registers accordingly.

Aplicaciones típicas
MC13892DJVKR2 es adecuado para 6 aplicacións: Personal Media Players (i.MX51), Personal Navigation Devices (i.MX35), Industrial Handheld Terminals (i.MX27), Battery Charging Management, Display Backlight LED Driving, Portable Audio Systems.
Personal Media Players (i.MX51)
The MC13892DJVKR2 is a natural power hub for i.MX51-based personal media players because its 4 adjustable bucks supply processor core and memory rails while its 12 LDOs power audio codecs, USB PHY, and peripherals from a single battery input. The integrated battery charger manages the Li-ion pack, and the 10-bit ADC monitors battery voltage and temperature without an external fuel-gauge IC. Because NXP co-designed the power sequencing with the i.MX51 boot flow, the PMIC guarantees correct rail ordering and reset timing, reducing bring-up risk. The trade-off versus discrete regulation is less rail flexibility, but for a fixed i.MX51 platform the integration dramatically shrinks BOM count and 7x7 mm board area.
Recomendado
Personal Navigation Devices (i.MX35)
For PND designs built on the i.MX35, the MC13892DJVKR2 integrates all battery-powered rails in one 139-ball device: bucks for the processor core, LDOs for GPS receiver, display, and audio sections, plus LED drivers for backlighting. The integrated charger handles vehicle-powered Li-ion charging, and the 10-bit ADC enables battery monitoring essential for a navigation device that must report remaining run time. NXP datasheet documentation explicitly targets PNDs for the MC13892 family. Using one PMIC instead of multiple regulators reduces height profile and total solution cost, important in slim portable navigation hardware where board space above the display is constrained.
Recomendado
Industrial Handheld Terminals (i.MX27)
The industrial temperature grade of the MC13892DJVKR2 suits rugged handheld terminals based on the i.MX27, such as warehouse scanners and mobile data collectors. Its 4 bucks and 12 LDOs power the processor, wireless module, display, and barcode optics, while the charger and ADC provide battery management for shift-long duty cycles and hot-swappable packs. The coin cell support preserves RTC and memory contents during battery swaps - a critical feature in logistics terminals. Compared with assembling a discrete regulator, charger, supervisor, and ADC chain, the single-IC approach cuts qualification effort and maintains consistent power-up behavior across production units, simplifying field diagnostics.
Recomendado
Battery Charging Management
Beyond powering the processor, the MC13892DJVKR2 functions as a complete single-cell Li-ion/Li-polymer charging subsystem: the integrated charger controls charge current and termination, and the 10-bit ADC tracks pack voltage, current sense, and thermistor temperature for safe charging profiles. This removes the need for a separate charger IC and fuel gauge in cost-sensitive portable designs. Because the charger shares the PMIC die with the regulators, thermal coordination is handled at the device level, though designers must still budget PCB copper for charger dissipation at high charge currents. Verify the charger current rating and JEITA-style temperature window in the manufacturer datasheet before finalizing the pack design.
Recomendado
Display Backlight LED Driving
DigiKey's product description lists display LED drivers among the MC13892DJVKR2's application functions, meaning the PMIC can drive the indicator/backlight LEDs of a handheld device directly from the same IC that powers the processor. This eliminates a dedicated LED driver IC and its wiring in media players and navigation units where a small number of display LEDs is needed. The LED channels are controllable via the device's register interface, allowing brightness management by software. For designs requiring high-current LED strings or advanced dimming curves, an external driver may still be added, but for typical handheld display indication the integrated channels reduce BOM and keep the power tree fully managed by one sequencer.
Recomendado
Portable Audio Systems
Media players and navigation units built around i.MX processors typically include an audio codec, and the MC13892DJVKR2's bank of 12 adjustable LDOs provides the low-noise analog and headphone-amp rails such codecs demand. Because the LDOs are independent linear regulators fed from the bucks, designers can dedicate one LDO per audio rail and keep switching artifacts out of the analog domain. The 10-bit ADC can monitor supply health, and the whole power tree stays under the PMIC's sequencing control so audio rails mute correctly during power transitions. For high-fidelity designs, confirm the chosen LDO's noise specification in the datasheet regulator tables and add local filtering capacitance at the codec supply pins.

Notas de diseño
The MC13892DJVKR2 implements i.MX-specific power sequencing: core rails must reach regulation in the order the i.MX boot ROM expects before reset deassertion. Program the PMIC's configuration registers (or verify factory defaults) against the i.MX51/35/27 reference manual power-section, and confirm the PWRON button and reset supervisor timing on your board. A mismatch in rail order is a leading cause of no-boot failures on i.MX platforms powered by the MC13892.
Place the 139-ball TFBGA with a via-in-pad or dog-bone escape strategy on a minimum 4-layer stack; the bucks need tight input loops - keep buck input capacitors within 2-3 mm of the corresponding VIN/ball pairs. Route switch-node traces short and wide, and dedicate a solid ground plane under the PMIC. Follow the NXP i.MX35/51 reference design layout, which demonstrates the recommended regulator component placement and thermal via array under the die-attach area.
Estimated: combined buck output currents in an i.MX51 media player commonly total 1-2 A at ~3.7 V battery input; even at ~90% buck efficiency the PMIC dissipates on the order of a few hundred milliwatts, plus LDO losses. Provide an array of thermal vias from the package area to inner ground planes per the datasheet thermal layout guidance, and measure die temperature via the ADC's internal channel during worst-case charging plus playback before finalizing the mechanical design.
When substituting ordering-code variants (MC13892DJVK, MC13892JVKR2, MC13892VKR2), do not assume identical die revisions - cross-reference data confirms package and functional equivalence, but die-level errata can differ. Check the NXP ordering table and silicon revision history, and validate charger termination behavior on real hardware before qualifying the substitute. Also confirm lead-free compliance of non-D suffixes against your RoHS requirements.
Información de cumplimiento
Compliance suffixes in the NXP ordering code (e.g., the D prefix in DJVKR2) relate to lead-free/RoHS grade, but explicit RoHS/REACH status was not stated in the verified web data - confirm on the official NXP product page before purchase.
