Power management integrated circuits (PMICs) are an essential component of any mobile and portable device. Battery charging technology is among the most important features of any mobile device. The LTC4052EMS8E-4.2#PBF is a battery charger IC from Linear Technology that is designed for use in a variety of mobile devices. This PMIC is designed to enable efficient, safe, and accurate charging of batteries for mobile applications.

The LTC4052EMS8E-4.2#PBF helps to eliminate the complexity of manual battery charging for mobile devices, providing features including input current regulation, charge current regulation, and chip shutdown when the battery is fully charged. Its small size and low input capacitance make it ideal for applications where space is at a premium, while its low operating temperature range ensures reliable operation in a variety of environmental conditions.

The LTC4052EMS8E-4.2#PBF is an advanced battery charger PMIC that provides multiple levels of protection by utilizing a constant voltage and current regulation scheme. This protects the device from overcharge, over-discharge, and overtemperature, while the chip is enabled by an external power supply. The LTC4052EMS8E-4.2#PBF also includes an additional circuit that monitors the battery voltage and shuts down the system when a minimum or maximum voltage is reached.

The LTC4052EMS8E-4.2#PBF application field covers a wide range of applications, from consumer electronics, wearables, cellular phones, netbooks, digital cameras and portable medical instruments to uninterruptible power supplies (UPSs) and automotive and industrial battery systems. It is designed to operate from a wide range of input sources such as a wall adapter, USB port, and automotive battery. Different charge currents can be programmed depending on the charger type, ranging from 300mA to 1A for USB-powered applications.

The LTC4052EMS8E-4.2#PBF monitors the battery voltage while charging and provides an end-of-charge (EOC) flag when the voltage reaches the targeted level. This flag can be used to disable further charging or signal the end of charging. When the voltage reaches the targeted level, the IC turns off its switching regulator and enters a low power bypass mode.

The LTC4052EMS8E-4.2#PBF also includes various protective features such as overvoltage protection, undervoltage lock-out (UVLO), thermal regulation, and current and voltage regulation. The device also features a charging status monitor output (CHRG) for signaling when the device has exited the bypass state and begun charging.

The LTC4052EMS8E-4.2#PBF is an advanced battery charger PMIC that is designed for use in a variety of mobile devices. It is designed to provide multiple levels of protection and offers features including input current regulation, charge current regulation, chip shutdown when the battery is fully charged, and overvoltage protection. Its compact size and low capacitance make it ideal for applications where space is at a premium and its low operating temperature range ensures reliable operation in a variety of environmental conditions.
