MPN： MC13892CJVKR2 ✗ 停產MC13892CJVKR2 概覽
A power management IC is a specialized semiconductor that consolidates multiple voltage regulators, chargers, supervision circuits, and interfaces into a single chip. Within the power management hierarchy, a PMIC sits above individual DC-DC converters and linear regulators, orchestrating multi-rail power sequencing for application processors in battery-powered systems such as smartphones, personal media players, and portable navigation devices.
Key features include four adjustable buck converters for processor core and memory rails, twelve adjustable LDOs for analog, I/O, and peripheral supplies, an integrated battery charger supporting USB charging, a 10-bit ADC for battery and system monitoring, and LED drivers for display backlighting. This level of integration replaces dozens of discrete components, reducing board area and bill-of-materials cost in handheld designs.
Architecturally, the MC13892 couples its switch-mode bucks for high-efficiency core supplies with low-noise LDOs for sensitive analog rails, and provides power sequencing control appropriate for i.MX processor power-up requirements. The 10-bit ADC enables fuel-gauging assistance and thermal monitoring through the host processor via its serial interface.
Typical applications include personal media players based on i.MX51/i.MX37, portable navigation devices on i.MX3x, and industrial handhelds built on i.MX27, where a compact single-IC power tree plus battery charging is required.
Design consideration: since this part is discontinued by NXP, new designs should plan for last-time-buy inventory or a redesign to a currently available i.MX PMIC companion.

典型應用
MC13892CJVKR2 適用於 6 應用s: Personal Media Players (i.MX51/i.MX37), Portable Navigation Devices (i.MX3x), Industrial Handhelds (i.MX27), USB-Charged Battery Systems, Display Backlight Driving, Battery and System Monitoring (10-bit ADC Telemetry).
Personal Media Players (i.MX51/i.MX37)
The MC13892CJVKR2 fits personal media players built on i.MX51 or i.MX37 processors because it generates the exact multi-rail power tree these SoCs require from a single IC: 4 adjustable bucks supply core and memory rails while 12 adjustable LDOs power analog, I/O, and audio domains with low noise. Its integrated battery charger with USB charging support accepts power directly from the player's USB port, and the 10-bit ADC enables battery-voltage monitoring for the fuel-gauge software. Display LED drivers backlight the screen without a separate driver IC. In a typical 7x7 mm layout, the PMIC sits adjacent to the processor, cutting board area versus a discrete buck/LDO/charger solution - a decisive advantage in slim media-player enclosures. Trade-off: buck efficiency gains are partially offset by LDO dissipation on low-current analog rails, acceptable at handheld power levels.

Portable Navigation Devices (i.MX3x)
Portable navigation devices based on i.MX3x processors use the MC13892CJVKR2 as the complete power subsystem: the 4 buck converters deliver processor core, DDR memory, and system rails with switching efficiency, while the 12 LDOs supply the GPS receiver front end, display, and touch controller with clean analog power. The integrated USB charger recharges the lithium battery from the car adapter or USB link, and the 10-bit ADC monitors pack voltage and die temperature for safe charge termination. LED drivers drive the backlight string for daylight-visible maps. According to the NXP product description, the MC13892 was explicitly designed for navigation devices in this processor family. Design consideration: place the buck converters' output LC filters close to the BGA to limit ripple reaching the GPS LDO inputs, preserving position accuracy.
推薦
Industrial Handhelds (i.MX27)
Industrial handheld terminals, data collectors, and scanners built on the i.MX27 benefit from the MC13892CJVKR2's industrial temperature grade and high integration. The 4 adjustable bucks power the ARM9 core and SDRAM, the 12 LDOs serve Ethernet PHY, display, and scanner interfaces, and the integrated charger keeps the removable battery pack topped up from USB or dock supplies. The 10-bit ADC supports battery health telemetry reported to fleet-management software, and LED drivers illuminate the device display. Consolidating the power tree into one 139-pin BGA simplifies certification and reduces assembly defects versus discrete multi-IC power stages. For legacy industrial designs already qualified on the MC13892, maintaining the same PMIC avoids re-qualification of the entire power sequencing scheme - important given the part's EOL status and last-time-buy planning.

USB-Charged Battery Systems
Any handheld product that charges a single-cell lithium battery over USB is a direct fit for the MC13892CJVKR2's integrated charging system. The charger negotiates power from the USB VBUS rail, regulates charge current, and uses the 10-bit ADC to track pack voltage for constant-current/constant-voltage termination - all without a separate charger IC. The 4 bucks and 12 LDOs then convert the battery voltage into the system rails, so one IC handles both charging and power conversion. This architecture shortens the design cycle for accessories and portable instruments that previously combined a charger IC with a multi-output regulator. Quantified benefit: removing two to three discrete ICs saves roughly 100-200 mm2 of board area and associated BOM cost, though designers should verify charge-current limits in the datasheet against their pack specification before finalizing thermal design.
推薦
Display Backlight Driving
The MC13892CJVKR2 includes dedicated display LED drivers, letting a handheld designer drive LCD backlighting directly from the PMIC instead of adding a dedicated boost LED driver. Combined with its 12 LDOs that supply the LCD panel and touch controller analog rails, the entire display power function - panel supply, backlight, and brightness control via the serial interface - lives in the same 7x7 mm BGA that powers the processor. This tight integration keeps brightness control synchronized with system power states managed by the i.MX host, improving power management during sleep modes. Performance consideration: backlight LED current capability is fixed by the MC13892 version; engineers should confirm the LED string configuration in the datasheet's LED driver section and budget thermal dissipation accordingly when driving maximum brightness continuously in outdoor-readable navigation or industrial handheld products.
推薦
Battery and System Monitoring (10-bit ADC Telemetry)
The MC13892CJVKR2's 10-bit ADC turns the PMIC into a telemetry hub for the i.MX host: battery voltage, charge current, and internal die temperature are digitized and reported over the serial interface, enabling host-side fuel gauging and thermal protection without a separate gauge IC. In personal media players and navigation devices, this supports accurate state-of-charge estimation and early over-temperature shutdown - both critical for lithium battery safety in consumer products. Engineers typically poll the ADC through the i.MX power-management driver, using thresholds to trigger charge termination or system shutdown. Design tip: the ADC accuracy depends on reference and layout; keep the battery sense line as a dedicated kelvin route to the BGA ball and filter switching noise from the bucks, since 10-bit resolution over the battery voltage range gives tens-of-millivolts effective LSB steps suitable for gauging but not precision metrology.

設計說明
The MC13892CJVKR2 is discontinued by NXP (see the MC13892CJVK product page, listed under Discontinued and Replacement Part Data). Do not start new designs with this part. For ongoing production, perform a last-time-buy based on documented consumption, secure broker stock only with authenticity warranties (e.g., date-code and packaging evidence), and register with NXP for the official replacement recommendation. Interchanging MC13892 version suffixes (A/B/C) without reviewing register-default and power-tree differences in the datasheet revision tables is a frequent cause of field failures in legacy i.MX platforms.
The 139-ball, 7x7 mm MAPBGA has a fine ball pitch that requires controlled-impedance fanout and sequential reflow. Place the buck converters' input capacitors and output LC filters within a few millimeters of the respective balls to minimize high-di/dt loop area; route battery sense lines as kelvin connections to the ADC balls to preserve 10-bit measurement accuracy. Follow the layout guidance in the NXP MC13892 hardware reference design for i.MX51/i.MX3x platforms, which defines recommended land pattern and via-in-pad rules for the thermal dissipation paths of the four bucks.
Verify charger thermal dissipation at maximum USB charge current: the integrated charger drops the difference between VBUS (nominal 5 V) and the battery voltage inside the MC13892. Estimated: charging a 3.7 V cell at 500 mA from 5 V USB dissipates about (5.0 - 3.7) x 0.5 = 0.65 W in the package, on top of regulator losses - factor this into the 7x7 mm BGA's junction temperature budget alongside buck/LDO losses and verify against the datasheet thermal resistance figures.
