MC13892JVK - i.MX PMUIC, 4 Buck + 12 LDO PMIC | NXP
MPN： MC13892JVK ✗ 停產MC13892JVK 概覽
A Power Management IC (PMIC) is an integrated circuit that consolidates multiple voltage regulators (typically buck converters and LDOs) along with supervisory functions such as power sequencing, voltage monitoring, battery charging, and thermal protection into one package. The PMIC sits between a single-cell Li-Ion/Li-Poly battery or wall-adapter input and the dozens of power rails that an application processor subsystem requires, replacing what would otherwise be 15 to 25 discrete regulators and significantly reducing both board area and quiescent current.
Key features of the MC13892JVK include four synchronous buck converters (typically configured at 1.05 A, 1.0 A, and dual lower-current rails), twelve low-dropout linear regulators ranging from 30 mA to 300 mA of output current, an integrated Li-Ion / Li-Poly battery charger with JEITA-compliant temperature sensing, a real-time clock supply, and a backlight LED driver capable of driving a string of series white LEDs. The chip also includes I2C control, programmable power-up / power-down sequencing, and hardware reset output to the host processor.
Architecturally, the device combines NXP's Smart Power technology with a 0.13 um mixed-signal process to deliver high buck-converter efficiency (>90 % at typical loads) while maintaining the low-noise analog performance required by the audio CODEC and RF transceiver rails of an i.MX-based handheld design. The on-chip charge management supports pre-charge, fast-charge, and termination states, and includes a thermistor input for JEITA safety temperature windows.
Typical applications include portable media players, personal navigation devices (PNDs), e-readers, smart industrial handhelds, wearable medical telemetry, and any battery-powered i.MX51/37/35/27 platform. The wide input voltage range (typically up to 6 V from USB / wall adapters) and the high level of integration make it a common reference design companion to the i.MX family.
When designing with the MC13892JVK, engineers should pay close attention to the buck-switcher inductor and capacitor selection to meet ripple targets, lay out the PBGA thermal balls on multiple inner copper pours to keep junction temperature below 105 C, and follow NXP's reference manual for the exact power-up sequence to prevent latch-up of the i.MX processor core supply.

典型應用
MC13892JVK 適用於 6 應用s: Portable Media Player Power Subsystem, Personal Navigation Device (PND), Handheld Industrial Terminal, Smart Mobile Handset (Legacy), E-Reader / E-Paper Tablet, Wearable Medical Telemetry.
Portable Media Player Power Subsystem
The MC13892JVK's combination of 4 buck converters, 12 LDOs, and an integrated Li-Ion charger makes it a single-chip power solution for portable media players based on the i.MX51 / i.MX37 application processors. The >90% buck efficiency at typical loads and the I2C-programmable power-up sequencing match the audio-DAC and RF-transceiver rail-up requirements of a media-player design. Unlike a discrete regulator array, the PMUIC keeps the bill of materials small, and the JEITA-compliant thermistor input protects the Li-Poly cell during fast-charge at elevated temperatures.
推薦
Personal Navigation Device (PND)
Personal navigation devices require multiple rails (core, memory, GPS LNA, backlight, audio) plus a Li-Ion battery charger, all of which the MC13892JVK delivers on a single 7x7 mm BGA. The buck / LDO combination supplies the i.MX35 host, the SDRAM, the GPS module, and the TFT backlight LED driver, while the integrated charger accepts a 5 V USB / wall input. The wide input voltage range and JEITA safety make it well suited to in-car cradle environments where ambient temperature can vary widely.
推薦
Handheld Industrial Terminal
Rugged handheld terminals for logistics, warehousing, and field-service applications typically use the i.MX27 or i.MX35 processor paired with a barcode imager, a WLAN / Bluetooth module, and a sunlight-readable LCD. The MC13892JVK provides the 4 buck rails needed for the processor core, memory, and I/O, plus 12 LDOs for the imager, display, and audio CODEC, while its battery-management block supports hot-swap from a wall adapter without processor reset. This consolidation reduces board area enough to fit inside a Pistol-grip form factor.
推薦
Smart Mobile Handset (Legacy)
Pre-smartphone feature phones and entry-level smartphones based on the i.MX applications processor used the MC13892JVK to consolidate power, charging, and user-interface LED control into a single chip. The integrated LED driver removes the need for a separate backlight controller, and the 12 LDOs power the baseband, RF transceiver, audio PA, and keypad backlight. The wide input range (up to 6 V from USB / wall adapter) and the JEITA thermistor path are still cited in legacy reference designs today.
推薦
E-Reader / E-Paper Tablet
E-readers and e-paper tablets based on i.MX processors benefit from the MC13892JVK's buck efficiency for long battery life and its low quiescent current on standby LDOs. The integrated charger accepts USB input while the I2C-programmable sequencing ramps the e-paper display rails in the correct order to prevent ghosting. The wide input voltage headroom allows direct connection to a solar-charging MPPT circuit or a USB-PD adapter in the field.
推薦
Wearable Medical Telemetry
Battery-powered wearable medical patches and patient telemetry devices that use i.MX27 or i.MX35 processors rely on the MC13892JVK to deliver low-noise analog rails for ECG / SpO2 front-ends while keeping quiescent current low to extend battery life. The buck converter's >90% efficiency at light loads, combined with 12 LDOs that can be individually shut down via I2C, allows designers to power down inactive sensor blocks between measurements. The JEITA-compliant charger and wide input range also support wearable charging cradles with USB input.

主要差異化特點
- Single-chip integration of 4 buck + 12 LDO + charger + LED driver for i.MX hosts (對比MC13892CJVK (Active))
- Integrated JEITA-compliant Li-Ion charger with thermistor input (對比MC13892CJVK (Active))
- Targeted at i.MX51/37/35/27 boot sequencing (對比MC13892CJVK (Active))
設計說明
Estimated: At 4 buck regulators each delivering ~500 mA at 3.3 V from a 4.2 V Li-Ion source, total power dissipation is ~4 x (4.2-3.3) x 0.5 = ~1.8 W, plus LDO drop and charger loss. The 139-PBGA (7x7) package must be soldered to a fully-thermalized PCB with at least 4 inner copper pours stitched with thermal vias under the central ball array to keep junction temperature below 105 C. In handheld enclosures with limited airflow, derate total system dissipation to <1.5 W.
Place the buck inductor and bootstrap capacitor as close as possible to the corresponding SWx and BSTx balls, and keep the high-di/dt switching loop area to a minimum to meet FCC / EN55022 radiated emissions. Use a star-ground topology tying the AGND balls to a single quiet ground island, and decouple every LDO output with at least 1 uF X5R ceramic within 2 mm of the output ball. Per NXP reference designs, a 4-layer FR-4 stack-up with a continuous ground plane on layer 2 is mandatory for EMI compliance.
Do not attempt to use the MC13892JVK with i.MX53 / i.MX6 / i.MX7 hosts - the power-up sequencing and default rail voltages are tuned specifically for i.MX51/37/35/27 boot ROMs and will not match newer processor requirements. Verify JEITA thermistor values against the exact NTC part number in the reference manual; using a 10 k vs 100 k NTC will disable fast-charge. Finally, because the part is Obsolete at NXP, design in the pin-compatible Active MC13892CJVK for new production to avoid end-of-life supply risk.
