What is S-8261ACHMD-G4HT2U PMIC?

The S-8261ACHMD-G4HT2U, introduced by Seiko Epson Corporation, is one of the most advanced power management integrated circuits, or PMICs, available in the market. It is a hybrid, dual channel, mixed signal device specifically designed for battery management applications. This device is designed to help reduce component costs, power usage, and improve overall system performance. Specifically, it contains an internal analog and digital controller, two configurable power channels, two power supply rails, and two linear regulators.

Application Field

The S-8261ACHMD-G4HT2U is specifically designed for battery management applications. Its internal analog and digital controllers provide the necessary control over battery voltage and current so that the battery can power up and down smoothly, and also charge quickly and efficiently. Its configurable power channels allow for greater flexibility with power management, allowing the controller to switch power sources automatically as needed. This flexibility also provides for better battery protection, helping protect the battery from overcharging and overdischarging.In addition, S-8261ACHMD-G4HT2U can help protect against overvoltage, undervoltage, and short-circuit hazards. It has built-in EMI (electromagnetic interference) and ESD (electrostatic discharge) protection, as well as an integrated gate driver for applying gate voltages to devices such as FETs (field-effect transistors) and SCRs (silicon-controlled rectifiers).The S-8261ACHMD-G4HT2U is commonly used in consumer electronics such as smart phones, tablets, and other mobile devices, laptop computers, and medical equipment.

Working Principle

The S-8261ACHMD-G4HT2U is a PMIC specifically designed for battery management applications. It contains an internal analog and digital controller, two configurable power channels, two power supply rails, and two linear regulators. When power is applied to the device, the analog controller uses external sensing pins to measure the battery voltage and current. Based on this information, the controller will then adjust the internal circuitry appropriately. The digital controller is responsible for the actual control of the battery state. It will adjust the power supply based on the current state of the battery and ensure that the battery is not overcharged or overdischarged.The device also contains two configurable power channels. These channels can be used to switch power sources as needed and provide better protection against overcharging, undercharging, and short-circuit hazards. Finally, the two integrated linear regulators allow for precise voltage regulation at a very low power consumption level. This helps maintain the battery in a safe and healthy state while it is being charged.

Conclusion

The S-8261ACHMD-G4HT2U is a PMIC specifically designed for battery management applications. It contains an internal analog and digital controller, two configurable power channels, two power supply rails, and two linear regulators. This PMIC is used in consumer electronics such as smart phones, tablets, laptops, and medical equipment. The S-8261ACHMD-G4HT2U is designed to help reduce component costs, improve power efficiency, and ensure battery safety by providing precise voltage regulation.
