The Samsung Galaxy J7 Prime (Model SM-G610F/G610G) is a legendary mid-range device known for its durability. For technicians and enthusiasts, the “Light IC” is a critical component, as it manages the high-voltage backlight required for the 5.5-inch PLS TFT display. J7 PRIME LIGHT Mobile Phone IC
Below is the detailed technical breakdown of the Integrated Circuits (ICs) found in the J7 Prime, focusing specifically on the Display/Light management and the broader Power Management system. J7 PRIME LIGHT Mobile Phone IC
1. Samsung J7 Prime Light & Display IC Specifications
In the J7 Prime, the display light is managed by a dedicated driver. While the main Power Management IC (PMIC) handles general power, this specific chip boosts the battery voltage (approx. 3.7V–4.2V) to the high voltage (15V–25V) required to light up the LCD backlight strings.
| Specification Parameter | Detail / Value |
| Component Name | Display Light / Backlight Driver IC |
| Part Number / Code | ISL98611IIZ-T (Commonly referred to as 98611) |
| Alternative Code | SM3004B (In some regional variants) |
| Function | DC-DC Boost Converter & LED Driver |
| Input Voltage ($V_{IN}$) | 2.5V to 5.0V (Typical Battery Range) |
| Output Voltage ($V_{OUT}$) | Up to 28V (Variable based on brightness) |
| Package Type | WLCSP (Wafer Level Chip Scale Package) |
| Number of Pins/Balls | 30-ball BGA (approx.) |
| Brightness Control | PWM (Pulse Width Modulation) via Application Processor |
| Associated Components | Boost Coil (Inductor), Diode, Filter Capacitors |
| Common Symptoms of Failure | Dark screen (graphics visible under light), flickering, no backlight |
2. Supporting Power Management IC (PMIC)
The Light IC works in tandem with the IF-PMIC (Interface Power Management IC). If your device has no light and won’t charge, the issue often lies here rather than the dedicated light chip. J7 PRIME LIGHT Mobile Phone IC
| Feature | Specification |
| Main PMIC Model | S2MPU05 |
| Secondary/IF-PMIC | S2MU005X (Commonly handles Charging & Flash LED) |
| Manufacturer | Samsung Semiconductors |
| Integration | Regulates LDOs for the Exynos 7870 Processor |
| Role in Lighting | Provides the enable signals ($EN$) and initial $V_{CC}$ to the Light IC |
3. General Device Hardware Context
To understand the load on these ICs, here is the hardware environment they operate in:
| Category | Specifications |
| Chipset | Samsung Exynos 7 Octa 7870 (14nm) |
| CPU | Octa-core 1.6 GHz Cortex-A53 |
| GPU | Mali-T830 MP1 |
| Display Type | PLS TFT LCD (Requires high-power backlight IC) |
| Resolution | 1080 x 1920 pixels (~401 ppi density) |
| Battery | 3300 mAh Li-Ion (Non-removable) |
| Charging | 5V / 1.55A (Standard Micro-USB) |
4. Technical Insights for Repair
If you are looking for these specifications for repair purposes, keep the following “Golden Rules” in mind:
-
The Coil Factor: Frequently, the “Light IC” is perfectly fine, but the Backlight Inductor (Coil) nearby has blown due to a short circuit or water damage. Always test the coil for continuity before replacing the IC.
-
Voltage Testing: With the phone on and the screen active, you should find around 15V to 22V on the output capacitor near the Light IC. If you only see battery voltage (~3.8V), the IC is not “boosting” and likely needs replacement.
-
Compatibility: The 98611 IC is also used in the Samsung Galaxy J5 Prime and some Grand Prime models, making it relatively easy to source from “donor” boards.
Note: IC replacement requires professional SMD soldering tools (Hot Air Station) and microscopic precision. Improper heat can damage the Exynos processor located on the opposite side of the board.
