Key Features and Functional Capabilities
1. Advanced Power Path Management
The SGM41511 utilizes NVDC (Narrow Voltage DC) management. This allows the system to remain powered even if the battery is completely depleted or removed. It prioritizes system power and uses “Supplement Mode” to pull current from the battery if the input adapter cannot meet the system load. SGM 41511 Original Mobile Phone IC
2. Fast Charging & High Efficiency
With a 3A charging capacity, it supports modern fast-charging protocols. Its 1.5MHz switching frequency allows for the use of small inductors, saving board space, while the 28mΩ BATFET ensures minimal heat generation during high-current discharge. SGM 41511 Original Mobile Phone IC
3. Comprehensive Safety Suite
The IC is designed to protect both the device and the user through:
-
JEITA Profile Support: Monitors battery temperature via an NTC thermistor (TS pin) to adjust charging in hot or cold conditions.
-
Thermal Regulation: Automatically reduces charge current if the internal junction temperature hits 80°C or 120°C.
-
Voltage Protection: Includes Input Over-Voltage Protection (ACOV) and Under-Voltage Lockout (UVLO).
4. USB On-The-Go (OTG)
The IC can reverse its operation to act as a Boost Converter, taking energy from the battery to provide a stable 5.15V output to the VBUS pin, allowing the phone to power external USB accessories like flash drives or keyboards.
Typical Pin Configuration (24-Pin TQFN)
-
VBUS: Charger input supply.
-
SW: Switching node (connected to inductor).
-
SYS: System voltage output.
-
BAT: Connection to the positive battery terminal.
-
SCL/SDA: I2C clock and data lines for host communication.
-
STAT: Open-drain output for charging status (LED indicator).
-
nINT: Interrupt output to notify the host of faults or status changes.
-
TS: Temperature sense input for the battery thermistor.
Note: For repair professionals, ensure the nQON pin is correctly handled, as it manages the “Ship Mode” exit and hardware system resets.
