MC13892AJVLR2 - PMIC 4-Buck/12-LDO i.MX PMU | NXP
MPN: MC13892AJVLR2 ✓ Hoạt độngMC13892AJVLR2 Tóm tắt
A PMIC (Power Management Integrated Circuit) is a category of power management IC that consolidates multiple DC-DC converters, LDOs, battery chargers, and supervisory functions into one silicon die. It sits at the top of the power-management hierarchy: PMIC > power management > mixed-signal IC > semiconductor. The MC13892AJVLR2 specifically belongs to the application-processor PMU subcategory that targets handheld and embedded designs where board area and rail sequencing are critical.
The device delivers four programmable synchronous buck converters (up to ~1.2 A each depending on rail), twelve LDOs for low-current analog and I/O domains, an I2C control interface for dynamic voltage scaling, real-time clock supply, and on-chip battery charging for single-cell Li-Ion/Li-Poly packs. Integrated features include power-on reset, watchdog timer, thermal protection, and a backlight LED driver. The 186-LFBGA package exposes all rails and the host control bus on the bottom side.
Typical applications include smartbook tablets, e-readers, smartphones, portable navigation devices, media phones, ultrasound medical handhelds, and other embedded handheld platforms based on i.MX processors. Designers typically route the buck outputs to the processor core, memory, and I/O, while LDOs feed radios, sensors, RTC, and analog peripherals; the integrated charger manages USB or wall-adapter input directly to the battery.
When designing in this PMU, pay close attention to the inductor selection on each buck output and the input capacitor bank near the BGA balls - poor placement can degrade ripple and efficiency. The I2C address and default rail voltages are strap-configured at first power-up; review the OTP defaults in the manufacturer datasheet before committing the layout.

Ứng dụng tiêu biểu
MC13892AJVLR2 phù hợp cho 6 Áp dụngs: Smartbook Tablet Power Tree, E-Reader and eBook Platform, Portable Navigation Device, Ultrasound Medical Handheld Probe, Smartphone / Media Phone, Industrial Handheld Data Terminal.
Smartbook Tablet Power Tree
The MC13892AJVLR2 is the canonical PMU for smartbook built on the NXP/Freescale i.MX51/i.MX53 application-processor family. Its four buck converters feed the processor core, system memory, and high-speed I/O rails directly, while the twelve integrated LDOs supply low-noise analog domains, the RTC, and peripheral sensors. Because the IC integrates a single-cell Li-Ion charger and I2C dynamic voltage scaling, the entire power section of a 7-inch smartbook fits on a small board area around a 12x12 mm BGA footprint. Using one PMIC instead of discrete regulators typically cuts the power-stage BOM by 30-40 percent and reduces the bill-of-materials count for handheld designs targeting sub-9 mm total z-height.

E-Reader and eBook Platform
Long-battery-life e-readers based on i.MX processors rely on the MC13892AJVLR2 to deliver ultra-low quiescent current standby and precise I2C-controlled voltage scaling. The device's twelve LDO outputs feed the e-paper display driver, touch controller, and front-light LED string individually, allowing independent power gating when the page is static. The integrated battery charger supports USB input directly, enabling weeks of standby time on a single charge. Designers pair the PMU with the host processor via the I2C control bus so the SoC can command deep-sleep modes and wake-up sequencing without external glue logic.

Portable Navigation Device
Portable GPS navigation devices use the MC13892AJVLR2 to power an i.MX processor, the GPS receiver module, the LCD backlight, and the speaker amplifier from a single Li-Ion cell. The four buck outputs handle the high-current core and memory rails, while the LDOs feed the sensitive RF and audio sections to keep supply noise out of the GPS baseband and the audio DAC. The on-chip LED backlight driver removes a separate boost-converter stage, shrinking the PCB further. Combined with the integrated charger accepting a 5V car-adapter input, the PMU is a single-chip power solution for the entire handheld navigator.

Ultrasound Medical Handheld Probe
Battery-powered handheld ultrasound probes use the MC13892AJVLR2 to satisfy the low-noise, low-EMI requirements of medical imaging while keeping the board compact. The four buck rails feed the i.MX host, the analog front-end, the transmit/receive beamformer, and the display driver; the twelve LDOs isolate the analog signal chain from digital switching noise. Medical designers value the integrated single-cell charger and the power-on-reset/watchdog combination that simplifies IEC 60601 safety certification paths. The 12x12 mm BGA footprint lets the entire power tree fit alongside the transducer stack and the wireless link in a hand-sized enclosure.

Smartphone / Media Phone
Compact media phones based on i.MX application processors leverage the MC13892AJVLR2 to consolidate the entire power tree into one BGA. The four programmable buck outputs feed the application core, the DDR memory, the wireless modem, and the multimedia accelerator; the twelve LDOs supply the audio codec, camera, sensors, and USB subsystem independently. Dynamic voltage scaling over I2C extends talk time by trimming core voltage under light load. The integrated Li-Ion/polymer charger and the power-path management allow the device to operate directly from a USB input or wall adapter without external charger ICs, which is a major PCB-area win for sub-10 mm phones.

Industrial Handheld Data Terminal
Rugged industrial handhelds - barcode scanners, portable data terminals, and field-service tablets - use the MC13892AJVLR2 to deliver all rails from a single hot-swappable Li-Ion battery. The four buck outputs drive the i.MX application processor, the barcode imager, and the radio module, while the LDOs power the keypad scanner, the indicator LEDs, and the secure-element. The on-chip battery charger accepts a 5V cradle or wall input, and the integrated RTC supply maintains time-of-day across battery swaps. Designers benefit from one BGA footprint consolidating what would otherwise be three to five separate regulators, simplifying EMI and thermal certification of the rugged enclosure.

Ghi chú thiết kế
Estimated: The 186-LFBGA 12x12 mm package requires a 6-8 layer PCB with continuous GND planes under the BGA balls for thermal dissipation. Place input bulk capacitors (>=22 uF ceramic) within 5 mm of the VIN balls and route each buck LX node with a 0.8-1.2 mm wide short loop to its inductor and output cap. Poor ground plane stitching under the BGA increases buck ripple by 2-3x and raises LDO noise floor.
Estimated: At typical smartbook rails (VCCORE ~1.0V/1.2 A, VCMEM ~1.5V/0.8 A, VCCIO ~3.3V/0.3 A) the PMU dissipates ~1.0-1.5 W total including charger losses, well within the LFBGA's thermal capability. Verify the worst-case VIN-VOUT differential on the highest buck and ensure dropout headroom of at least 200 mV to keep efficiency above 85 percent.
The MC13892AJVLR2 OTP defaults are strap-configured at first power-up; once programmed the defaults are fixed for the lifetime of the part. Always review the OTP default table in the manufacturer datasheet before committing the layout, since changing the OTP defaults requires swapping to the B- or C-step revision. Mixing A-step and C-step silicon on the same board layout is supported but requires identical OTP defaults.
Estimated: Route the I2C SCL/SDA traces with 4-8 mil microstrip and place a 10 kohm pull-up to the host VCCIO rail near the PMU. Keep the I2C bus clear of the buck LX switching nodes to avoid coupling. Add an RC snubber (10 ohm + 1 nF) on each buck LX node if EMI scan margins are tight.
