Product details
Overview
SC900841JVK from Freescale Semiconductor is a highly integrated Power Management IC (PMIC) for ultra-mobile platforms, delivering 29 regulated voltage rails-including nine high-frequency switching regulators (1.0–4.0 MHz), 17 LDOs, and three 3.3 V power switches-alongside a switching-mode Li-Ion battery charger, 22-channel 10-bit ADC, RTC, 8 GPIO/GPO, and LED backlight drivers. It targets Mobile Internet Devices (MID), tablets, and netbooks requiring compact, multi-rail power sequencing and system-level integration.
For engineers reviewing the SC900841JVK datasheet, SC900841JVK pinout, SC900841JVK application, or SC900841JVK equivalent, key selection criteria include its 338-MAPBGA package, -40°C to +85°C operating range, SPI/Mini-SPI programmability, and support for dual-chip power architecture with SC900842 in ultra-mobile platform designs.
Technical Context
The SC900841JVK implements a partitioned power architecture optimized for heterogeneous ultra-mobile SoCs, with dedicated DC/DC converters for CPU cores (VCC, VNN), memory (VDDQ, VCCPDDR), communications (VYMX3G, VYMXPA, VOTG), display (VBKLT), and always-on subsystems (VAON, RTC). Its 22-channel ADC supports touch screen interface and internal thermal/voltage monitoring.
Control is executed via dual serial interfaces: a full-speed SPI (up to 25 MHz) for configuration and status readback, and a Mini-SPI for low-overhead register access. Power state management includes Hard/Soft Mechanical Off, Power On, and thermal shutdown with junction temperature monitoring up to +125°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SC900842 | Companion PMIC in same family; lacks VBKLT boost, has enhanced comms rail set (VYMXGPS, VOTG); shares SPI/Mini-SPI protocol | Designed for split-power architecture where SC900841 handles core/memory/display and SC900842 handles RF/comms/peripherals | Select SC900842 only when implementing dual-PMIC topology per Freescale's ultra-mobile reference design |
| TPS65910A3RSLR | Texas Instruments PMIC with 10 DC/DC + 10 LDOs; no integrated battery charger or backlight driver; 196-BGA, 10 mm × 10 mm | Targeted at OMAP4/AM335x platforms; requires external charger IC and LED driver; lower rail count but smaller footprint | Choose TPS65910A3RSLR for cost-sensitive OMAP-based designs where backlight and charging are handled externally |
Compared with SC900841JVK, SC900842 extends comms rail capability but omits display power, while TPS65910A3RSLR offers smaller package and TI ecosystem support but requires additional ICs for full system power-making SC900841JVK optimal for integrated ultra-mobile platforms needing single-chip completeness.

FAQ
What is the maximum input voltage rating for SC900841JVK?
The SC900841JVK has a maximum input voltage rating of +4.7 V on VPWR under extended conditions, and +4.4 V under normal operating conditions. Exceeding these limits may cause permanent damage. The device also specifies absolute maximum ratings of +20 V for charger input and +28 V for LCD backlight circuitry, which are isolated from the main VPWR domain.
Does SC900841JVK support both USB and battery charging simultaneously?
No, SC900841JVK does not support simultaneous USB and battery charging. Its power path management detects valid USB (USBDET = 1) or battery (BATDET = 1) presence and selects the appropriate source. In Soft Mechanical Off state, it draws 5–50 mW depending on detected source, but charging occurs from one source at a time per Freescale's power state diagram.
How many GPIOs and GPOs does SC900841JVK provide?
The SC900841JVK provides 8 interrupt-capable GPIOs, 8 general-purpose outputs (GPOs), and 4 dedicated GPOSW pins for controlling platform-specific switches. All GPIO/GPO signals are software-configurable via SPI registers and support level-triggered interrupts for system event handling.
What is the resolution and accuracy of the SC900841JVK ADC?
The SC900841JVK features a 22-channel, 10-bit successive-approximation ADC with typical INL/DNL < ±1 LSB. It supports internal temperature sensing and external inputs including touchscreen X/Y coordinates, battery voltage, and system rail monitoring-with full-scale range selectable per channel.
Is SC900841JVK pin-compatible with other members of the 900841 family?
Yes, all variants in the 900841 family-including SC900841JVK-share identical 338-MAPBGA pinout and mechanical footprint. Differences between variants (e.g., SC900841JVK/R2 vs. SC900841JVK/R1) relate only to mask revision and minor electrical characterization updates, not pin function or assignment.
