It8995e 128 Datasheet 2021

It supports the standard, a robust protocol for negotiating power contracts between a source (like a charger) and a sink (the laptop). This allows the device to request and deliver up to 100W of power, enabling fast charging and the ability to power a wide range of peripherals directly through the USB-C port.

Embedded controllers must be resilient because if they fail, the entire system fails to boot. The IT8995E-128 includes: Built-in Protections: It features integrated electrostatic discharge (ESD) protection overheating safeguards Environmental Resistance:

The "128" designation in the part number typically refers to the pin count or a specific firmware variant. The IT8995E is packaged in a (Low-profile Quad Flat Package). Below are the core specifications derived from the datasheet family:

: Controls the power-on sequence and battery charging cycles. Thermal Control : Manages fan speeds and monitors system temperatures. Input/Output it8995e 128 datasheet

: Built-in ESD protection (electrostatic discharge).

The IT8995E-128 often requires firmware specifically matched to the laptop motherboard model. The chip supports programming via I2C or a dedicated keyboard interface.

Communicates with the laptop battery's internal fuel gauge via the System Management Bus (SMBus) to read state of charge (SoC), voltage, health, and temperature. It supports the standard, a robust protocol for

In your programmer software, select the specific motherboard model or manually configure the pins for EDI_CLK , EDI_DO , EDI_DI , and EDI_CS# .

If you are searching for the , you are likely troubleshooting a laptop motherboard, working on embedded system design, or performing a board-level repair on a high-end notebook. This chip acts as the central nervous system for legacy and low-speed peripherals, managing everything from keyboard controllers to thermal monitoring.

Measure the voltage on the VSTBY pins (typically 3.3V). If this voltage is missing or pulling low, the chip may have an internal short circuit. Thermal Control : Manages fan speeds and monitors
