: Low-Profile Quad Flat Package with 128 pins ( LQFP-128 or TQFP-128 ).
It interacts via SMBus/I2C with the smart battery and the charging IC to regulate current and voltage safely. 3. General Pinout Configuration & Signal Families
In these systems, the IT8995E-128 works in tandem with the main chipset (e.g., Intel HM170 or Whiskey Lake-U42) to manage everything from the high-speed NVMe SSD slots to the external USB-C charging ports.
The laptop fails to respond to power button presses while raw charging input voltages ( 19V / 20V ) remain correct. it8995e 128 datasheet
The IT8995E-128 is a multi-functional chip integrating several key subsystems:
: Employs dedicated programming paths (such as EDI or shared I2C channels) used by diagnostic tools to rewrite internal eFlash. Motherboard Repair and Programming Requirements
The stands as a testament to the high level of integration in modern laptop design. It is a sophisticated, programmable embedded controller that merges legacy Super I/O functions with advanced features like USB Power Delivery 3.0. : Low-Profile Quad Flat Package with 128 pins
The IT8295E chip can be used in various applications, including:
| Feature | IT8995E-128 | IT8728F (ITE) | NCT6779D (Nuvoton) | |---------|-------------|---------------|--------------------| | Package | LQFP-128 | LQFP-128 | LQFP-128 | | ADC bits | 12-bit | 10-bit | 12-bit | | Fan control | 3 PWM, 4 tach | 4 PWM, 5 tach | 5 PWM, 6 tach | | Infrared | Yes (CIR) | No | Yes | | GPIO count | 64 | 48 | 72 | | Typical application | Industrial MB | Desktop MB | High-end MB |
The IT8995E-128 is a critical component in power distribution, physical user input interfaces, and thermal safety for modern notebooks. When performing board-level repairs, always consult the exact schematic and boardview files for your specific motherboard model, as the exact mapping of its 128 pins is highly customizable by the laptop manufacturer.

If the EC firmware corrupts or its thermal ADC lines fail, it may spin the cooling fan at 100% continuously as a failsafe.
Pressing the power button does nothing. No LEDs light up. The laptop appears completely lifeless. Diagnostic Steps:
