Power management integrated circuits (PMIC) play a very important role in the development of modern electronics. They make possible the efficient use of electrical energy to drive applications on a variety of mobile, consumer and industrial products. PMIC Battery Chargers are specialized types of power management integrated circuits dedicated to charging and maintaining the batteries used in portable and consumer electronics. The LTC4120EUD-4.2#TRPBF is a PMIC battery charger specifically designed to reliably manage the charging of Lithium-ion batteries under a wide range of conditions.

The LTC4120EUD-4.2#TRPBF is specifically designed for use in products with high battery charging performance requirements such as tablets, smartphones and portable devices, but it is also suitable for industrial applications. It allows manufacturers to reduce the total system BOM count, lower the design cycle time, decrease PCB area and integrate all features needed for li-ion battery charging, monitoring and protection. The LTC4120EUD-4.2#TRPBF is a highly integrated charger that contains a constant-current/constant-voltage (CC/CV) battery charger, battery isolation switches and analog battery sense circuitry.

The LTC4120EUD-4.2#TRPBF allows for a wide input voltage range of 5V to 16V, with a high-efficiency operation up to 94%. This high efficiency allows the LTC4120 to charge a wide range of lithium-ion batteries, including cylindrical, prismatic, pouch and micro-battery cells. The LTC4120EUD-4.2#TRPBF also includes several safety features, such as over-voltage, under-voltage, over-temperature and short-circuit protection.

The LTC4120EUD-4.2#TRPBF is unique in that it is able to detect when two chargers are connected to the same Li-ion battery and will disconnect, thus preventing a short circuit. This allows the product to operate safely even in harsh industrial environments. It also features a low quiescent current of 1µA in shutdown mode, and an adjustable output voltage range of 2.5V to 4.2V, making it suitable for a wide range of applications.

The LTC4120EUD-4.2#TRPBF also features a programmable input current limit and an output power limit. This allows for a high degree of flexibility in system design, as the input and output power limits can be set to ensure that the battery is always charged at an optimal rate. Furthermore, the device can also be set to be in low power mode when the battery reaches a full charge, and will switch back to high power mode when the battery voltage drops and needs to be topped-off again.

The LTC4120EUD-4.2#TRPBF is a highly efficient, feature-rich and reliable PMIC battery charger suitable for a wide range of applications. It is an excellent choice for applications which need to charge lithium-ion batteries reliably and quickly with minimal input power, while also offering safety and protection features. It can also be used as an isolator switch in general power supply systems and systems with multiple batteries.
