MC13892BJVL Übersicht
A Power Management IC (PMIC) is a class of mixed-signal power management IC that consolidates multiple voltage rails, battery charging, real-time clock supply, and sometimes audio or display drivers into one device. PMICs are widely used in SoC-based systems where a single chip must produce every voltage domain required by the host processor, memory, and peripherals, while also supervising power-up and power-down sequencing.
The MC13892BJVL integrates four synchronous buck converters that power the application processor core, memory, and I/O domains, plus twelve low-dropout regulators that supply radios, displays, and analog blocks. The device also includes battery management functionality (charger interface, coulomb counter, and backup battery switching), LED drivers for display and keypad backlight, and a wide range of housekeeping functions. The device supports dynamic voltage scaling and I2C/SPI control for host-driven power state changes.
The architecture combines a high-frequency switching regulator core for the buck converters with low-noise linear regulators for sensitive RF and audio supplies. Programmable sequencing, hardware event detection (battery insertion, USB attach, power button), and integrated passives reduce external component count significantly compared to discrete power solutions, which is essential for handheld product form factors.
Typical applications include portable media players, GPS personal navigation devices, e-book tablets, handheld industrial data terminals, and any i.MX51/i.MX37-based embedded platform. The MC13892BJVL is the standard NXP reference PMIC for the Freescale i.MX51 reference design (MX51 Babbage board ecosystem) and the SCALEA reference platform.
A practical trade-off is the part's large 186-ball BGA package, which requires a multi-layer PCB with microvia technology and careful thermal management. Designers should follow the NXP reference design layout guidelines and the recommended decoupling scheme for proper buck converter ripple and transient response.

Typische Anwendungen
MC13892BJVL ist geeignet für 6 Anwendungs: Portable Media Player (PMP), GPS Personal Navigation Device (PND), eBook Reader / Tablet, Industrial Handheld Data Terminal, Set-Top Box / Smart Home Hub, Portable Medical / Health Monitor.
Portable Media Player (PMP)
The MC13892BJVL is the reference PMIC for i.MX51-based personal media players because it integrates the four buck rails that feed the ARM core, mDDR memory, and I/O domains with a single BOM. Its 12 LDOs supply audio CODEC, headphone driver, display controller, and WiFi/Bluetooth radio, all sequenced through I2C to match the i.MX51 power-up order. The integrated Li-Ion charger with coulomb counter extends battery life for hours of video playback, and the LED drivers drive keypad and LCD illumination. The 186-LFBGA 12x12 mm package lets handheld designers fit the entire power tree plus BJT peripheral drivers in a small PCB area, which is the primary design goal for portable media products.

GPS Personal Navigation Device (PND)
Handheld GPS navigation devices built around i.MX37 or i.MX35 application processors rely on the MC13892BJVL to power the host MCU plus the GPS receiver front-end, the touch screen controller, and the SD card bus. The four buck converters provide low-ripple power to the GPS RF chain, which directly improves DF (dynamic figure) sensitivity and cold-start TTFF (time-to-first-fix). Twelve LDOs cleanly isolate the analog audio block and the touch-screen ADC references, while the integrated Li-Ion charger supports in-car USB or wall-adapter charging. Compared to discrete regulator solutions, the MC13892BJVL reduces PCB area by ~60 percent and cuts BOM cost in the navigation reference design.
Empfohlen
eBook Reader / Tablet
The MC13892BJVL is well suited to i.MX51 or i.MX35 powered eBook readers and tablets because the part combines a low-standby quiescent current with fast wakeup for the e-ink or LCD refresh bursts. The four bucks drive the i.MX core, system memory, and graphics, while the 12 LDOs quietly bias the E-ink driver, the touch-screen controller, and the WiFi module. The integrated coulomb counter provides accurate battery fuel gauging so the UI can report percent depletion to within 1 percent for weeks of continuous reading. NXP's reference schematics use the MC13892BJVL with the i.MX51 for cost-sensitive E-ink tablets.
Empfohlen
Industrial Handheld Data Terminal
Industrial data terminals built around i.MX35 application processors use the MC13892BJVL because the part is rated industrial temperature grade and integrates battery management, regulators, and LED drivers in one LFBGA-186 package. The four buck converters feed the ARM core and external memory, while twelve LDOs drive barcode scanner, keypad, and WiFi/Bluetooth radios. The integrated Li-Ion charger supports hot-swap and backup battery operation, which is essential for warehousing and logistics terminals that cannot lose power mid-shift. The compact BGA footprint enables ruggedized housing with metal frames for drop protection without sacrificing power density.

Set-Top Box / Smart Home Hub
Set-top boxes and smart-home hubs based on i.MX51 or i.MX37 use the MC13892BJVL to consolidate all power rails, including the HDMI PHY, the Ethernet MAC, and the flash memory bus, into a single chip. The part's sequencing ensures the i.MX host, the DDR memory, and the HDMI transmitter power up in the correct order, preventing latch-up and brown-out conditions. The 12 LDOs provide clean, low-ripple bias for the HDMI analog block, which improves signal integrity and CEC (consumer-electronics-control) compatibility. Smart-home hub designers value the integrated LED drivers for status indication without needing external MOSFETs.

Portable Medical / Health Monitor
Portable medical and wellness monitors that pair an i.MX27 application processor with the MC13892BJVL benefit from the part's integrated Li-Ion charging, accurate coulomb counting, and the 12 LDOs that cleanly bias analog front ends such as ECG, pulse-oximeter, and temperature sensors. The four buck converters provide high-efficiency conversion for the host and flash storage, while the LDOs provide the low-ripple bias required by precision ADC references for medical-grade measurements. Integrated battery fuel gauging supports accurate runtime prediction for both consumer and clinical health products. Compared to discrete solutions, the single-chip integration shortens FDA submission cycles by reducing the bill of materials and software dependency count.

Designhinweise
The 186-LFBGA package has 0.8 mm ball pitch, which requires a 4-layer or 6-layer PCB with microvia (laser-drilled) via-in-pad stack-up. Use non-solder-mask-defined (NSMD) pads of 0.4 mm diameter and route the inner-layer planes as solid ground/power pours below the BGA to provide thermal dissipation and return paths for the buck converters.
Estimated: with all four bucks delivering 1.0 A each at 80% efficiency from a 4.2 V Li-Ion input, total internal dissipation is roughly 1.0 W (buck losses) plus 0.3 W (LDO losses), so total ~1.3 W. With theta_JA of approximately 25 C/W on a 4-layer JEDEC board, junction temperature rise is ~33 C above 25 C ambient, leaving comfortable headroom. Add a copper pour under the package for margin if loads are higher.
Do not connect USB_VBUS directly to the battery charger input; always use the proper protection FETs and follow the MC13892 datasheet application circuit, otherwise the i.MX boot sequence may fail. Decouple each buck output with the exact capacitor values (typically 22 uF X5R) specified in the datasheet reference design; undersized output caps cause ripple that disrupts the i.MX core PLL.
Compliance-Informationen
