MC13892AJVK Descripción general
What is a PMIC? A Power Management Integrated Circuit (PMIC) is a highly integrated semiconductor device that consolidates multiple voltage regulators, battery management functions, and often user-interface features (LED drivers, keypad scanners, RTC, ADC channels) into a single chip. In the broader taxonomy, a PMIC sits below the power-management category and above discrete DC-DC converters and LDOs; it is the central power orchestrator of any battery-powered application-processor platform. By replacing dozens of discrete regulators, a PMIC reduces board area, simplifies power sequencing, and improves overall system efficiency.
Key features of the MC13892AJVK include: four synchronous buck converters (SW1-SW4) capable of powering the application processor core, memory, and I/O rails; twelve general-purpose LDOs for auxiliary supplies; integrated battery management with charger, coulomb counter, and backup-battery switchover; a 10-bit ADC for system monitoring; multiple GPIO pins; and an SPI/I2C control interface for dynamic voltage scaling. The device supports dynamic voltage-frequency scaling (DVFS) by slewing buck output voltages under software control, which dramatically reduces processor power consumption in portable use cases.
Typical applications include personal media players, GPS / navigation devices, portable industrial terminals, e-readers, and other handheld/mobile devices based on i.MX application processors. The wide input range (typically 2.7 V to 4.5 V from a single-cell Li-Ion cell) and the high integration level make the MC13892AJVK the default companion chip for legacy i.MX designs.
When designing with this part, pay close attention to the inductor and capacitor selection for the buck converters, follow the recommended PCB layout in the datasheet, and use the NXP evaluation board layout as a starting point. Confirm power-up sequencing via the I2C/SPI control interface matches your processor's rail-requirements.

Aplicaciones típicas
MC13892AJVK es adecuado para 6 aplicacións: Personal Media Player (PMP) Power Subsystem, Portable GPS / Navigation Device, Handheld Industrial Terminal / Data Collector, E-Reader / E-Ink Display Device, Set-Top Box / Smart-Home Hub (i.MX based), Portable Medical Patient Monitor.
Personal Media Player (PMP) Power Subsystem
The MC13892AJVK is the canonical NXP PMIC for PMP designs based on i.MX37 / i.MX51 application processors. Its four buck converters supply the ARM core, DDR memory, and peripheral I/O rails, while the twelve LDOs supply audio CODEC, display controller, and connectivity subsystems. The integrated Li-Ion charger and RTC backup domain eliminate the need for an external charger IC and discrete RTC chip, reducing the PMP power-section BOM by 30-40% versus a discrete regulator tree.
Recomendado
Portable GPS / Navigation Device
For portable GPS / PND designs the MC13892AJVK provides all rails required by an i.MX35 / i.MX27 application processor, the GPS receiver IC, the TFT display backlight, and the audio amplifier. Dynamic voltage scaling via the SPI/I2C control interface lets the system throttle the processor core during standby, extending battery life on a single Li-Ion cell. The integrated LED backlight drivers directly drive the navigation-display backlight without a separate charge-pump IC.
Recomendado
Handheld Industrial Terminal / Data Collector
The MC13892AJVK is widely deployed in rugged handheld terminals and barcode scanners based on i.MX35, where its wide input range (2.7 V to 4.5 V) tolerates battery sag during high-current scans. The integrated coulomb counter provides accurate battery fuel-gauge data, while the twelve LDOs supply Wi-Fi/Bluetooth modules, the LCD, and the keypad scanner. SPI/I2C programmability lets the firmware disable unused LDOs during sleep to extend shelf life on the shop floor.
Recomendado
E-Reader / E-Ink Display Device
For e-reader applications the MC13892AJVK supplies the i.MX35 / i.MX51 application processor core and the E-Ink display controller, with dynamic voltage scaling used aggressively during page-refresh events. The low-Iq LDO set keeps standby current low enough for the multi-week standby time expected of e-readers. The integrated backup-battery switchover preserves book-mark / RTC state across main-battery swaps.
Recomendado
Set-Top Box / Smart-Home Hub (i.MX based)
In wall-powered smart-home hubs and set-top boxes based on i.MX27 / i.MX37, the MC13892AJVK provides the entire regulated voltage tree, eliminating dozens of components. The SPI/I2C control interface allows the host processor to turn off unused rails during deep-sleep, while the integrated RTC backup-battery domain retains the system time across brief power interruptions.
Recomendado
Portable Medical Patient Monitor
Portable patient monitors based on i.MX35 use the MC13892AJVK to supply the ARM core, the analog signal-conditioning front-end, and the TFT display, all from a single Li-Ion battery pack. The integrated 10-bit ADC monitors battery voltage, die temperature, and key system rails, providing telemetry for the host. The high level of integration reduces PCB area, which is critical for wearable medical form factors.

Notas de diseño
Use the NXP MC13892 evaluation-board PCB layout as a starting point - the 139-MAPBGA requires a microvia (laser-drilled) stack-up to escape the inner balls. Place the buck inductors and input/output capacitors as close to the corresponding BGA balls as physically possible, with the ground-return loop minimized. Keep noisy switching currents away from the analog LDO output caps to avoid coupled ripple.
The four buck converters each require a shielded power inductor (typically 1.0-2.2 uH, low DCR) plus input and output ceramic capacitors (10-22 uF X5R). Select inductors rated for the peak buck current plus 30% derating, and ensure the input capacitors are placed within 2-3 mm of the high-side FET pins to suppress switching-node ringing.
Do not power the MC13892AJVK from a supply above 4.5 V without an upstream regulator - the part is designed for a single Li-Ion cell input. Power-up is wrong without a verified I2C/SPI control sequence from the host processor; consult the datasheet's Power-Up Sequencing chapter before first bring-up.
At maximum load (all four bucks at full output and all twelve LDOs enabled), the MC13892AJVK can dissipate up to approximately 1 W in the 7x7 mm MAPBGA. Use a 4-layer PCB with a continuous ground plane and thermal vias under the exposed pad-style balls (if applicable per datasheet) to keep junction temperature below 100 C in enclosed handheld enclosures.
