MC13892VL - 5/28V PMIC for i.MX | NXP Semiconductors
MPN： MC13892VL ✗ 停產MC13892VL 概覽
What is a PMIC? A Power Management Integrated Circuit (PMIC) is a single-chip regulator that consolidates multiple DC-DC converters, LDOs, charge controllers, and power-sequencing logic into one device, simplifying portable designs by replacing dozens of discrete components and enabling programmable multi-rail start-up. PMICs sit in the power management hierarchy above discrete voltage regulators, and below the SoC they supply, acting as the intelligent power backbone for an application processor.
The MC13892VL provides a programmable buck switching regulator core for the processor Vcore, multiple LDOs for peripherals, a USB-OTG compliant boost, an LED driver array, a touch-screen interface, a 10-bit ADC for battery monitoring, and an SPI/I2C interface for host control. According to the manufacturer datasheet, it directly supports the power-rail requirements of the i.MX51 family with hardware-programmable output voltages and sequence timing.
Although the device is now classified as EOL (End of Life), it remains valuable as a reference design for legacy i.MX-based smartbooks, eBooks, portable navigation systems, smartphones, and ultrasound medical equipment. The wide 5 V to 28 V input range covers both single-cell Li-ion USB supplies and 2-cell industrial battery stacks, making it attractive for tablet and rugged-handheld use cases. Designers integrating this part should verify the latest NXP product-change notifications and consider the pin-compatible MC13892JVL variant or newer PF0100 series for new designs.

典型應用
MC13892VL 適用於 6 應用s: i.MX51 Smartbook / Tablet Power Tree, Portable Navigation Device (PND), eBook Reader Power Management, Handheld Ultrasound Medical Equipment, Smartphone and Media Phone Platforms, Industrial Handheld / Rugged Mobile Terminal.
i.MX51 Smartbook / Tablet Power Tree
The MC13892VL's 5-28 V buck/boost core and programmable multi-rail outputs supply the i.MX51 Vcore, memory, and peripheral rails from a single USB or 2-cell battery source, eliminating the multi-IC power tree typical in smartbook motherboards. Per the NXP datasheet, the SPI/I2C programmable sequencing matches the i.MX51 power-on order, reducing external logic.

Portable Navigation Device (PND)
Portable navigation hardware needs a wide-input PMIC tolerant of automotive cradles and Li-ion packs. The MC13892VL accepts 5-28 V on a single rail and integrates battery management plus LED backlight drivers sized for GNSS displays, making it a one-chip solution for PND reference designs that pair an i.MX host with a TFT panel.
推薦
eBook Reader Power Management
eBook readers using i.MX processors benefit from the MC13892VL's low-standby quiescent current and integrated E-ink display LED drivers. The built-in 10-bit ADC monitors the Li-ion cell accurately through charge/discharge cycles, while the SPI interface lets the application processor dynamically trim Vcore during page-refresh low-power states.
推薦
Handheld Ultrasound Medical Equipment
Medical handheld ultrasound carts and probes demand long battery life and silent operation. The MC13892VL's switching architecture and integrated LED drivers make it a strong fit, with the integrated 10-bit ADC enabling real-time battery telemetry needed for IEC 60601-1-compliant run-time indicators on the cart display.
推薦
Smartphone and Media Phone Platforms
Media phones and feature phones built around i.MX27/i.MX35 silicon use the MC13892VL to consolidate battery charging, multiple LDOs, and backlight drive in a single 186-LFBGA. The IC's 5-28 V tolerance and built-in touch-screen interface reduce board area in the slim phone form factor without sacrificing user-interface responsiveness.
推薦
Industrial Handheld / Rugged Mobile Terminal
Rugged industrial handhelds powered from 2-cell or 12 V vehicle supplies benefit from the MC13892VL's wide 5-28 V input window and programmable sequencing. The integrated LED drivers can drive both the LCD backlight and the keypad illumination from a single BGA, and the touch-screen interface streams directly to the i.MX LCDIF peripheral.

設計說明
The MC13892VL accepts 5-28 V on its main supply but expects a tightly regulated 5 V bias for the LED driver stage. Estimated: with VIN = 12 V and a 5 V/0.5 A bias load, the buck core must reject ~7 V, so verify the inductor saturation current rating is at least 1.5x the steady-state peak to avoid saturation during cold-crank transients.
In the 186-LFBGA (12x12 mm) package, the thermal pad must be soldered to at least four thermal vias on the top layer for adequate heatsinking to inner copper planes. Estimated: at 2 W dissipation the junction-rise above ambient is roughly 25 C with a properly stitched thermal via array, but can exceed 60 C on a poorly thermalized board.
Place all input/output ceramic capacitors within 2 mm of the BGA balls to minimize parasitic inductance on the switching nodes. Use a 4-layer stack-up with a dedicated ground plane directly under the PMIC; keep digital SPI/I2C traces at least 3 mm away from the switched-phase nodes to avoid injected noise on the host interface.
Do not apply input voltages above 28 V or below 5 V - the part lacks undervoltage lockout hysteresis and may misbehave during connector-insertion transients. Also ensure the touch-screen reference is decoupled separately from the audio supply; otherwise the touch interrupt lines can couple into the headset return path.
合規資訊
Compliance information not explicitly listed in verified distributor sources; request RoHS/REACH certificate from supplier for EU-restricted applications. AEC-Q100 is not applicable since this part is intended for consumer/industrial handheld platforms rather than automotive ECUs.
