The LTC1759CG#PBF is a battery charger PMIC (power management IC) used in applications that require reliable power sources and stable voltages. This state-of-the-art PMIC is designed to efficiently manage rechargeable batteries, such as lithium-ion, alkaline, nickel-metal hydride, and lead acid, with a maximum current rating of up to 4.8A. It provides excellent charging and high performance, with automatic charge termination, protection monitoring, and status output pins. The LTC1759CG#PBF offers a wide range of current limit and charge termination voltages, and can be used in a wide range of solutions, from industrial and embedded systems to consumer electronics.

The LTC1759CG#PBF is designed to provide reliable and controlled charging of multiple battery chemistries. It utilizes a programmable constant-current/constant-voltage (CC/CV) control algorithm with a programmable current limit, allowing the user to specify the charging current, charging cycle parameters, and maximum cell voltage. The charger provides a status pin to indicate when the charge is complete, an active low reset pin to reset the charger, a voltage monitoring pin to detect when the battery has reached its optimum charge level, and a sense pin to precisely monitor the current through the battery. Additionally, the charger features over-temperature and under-voltage protection.

The LTC1759CG#PBF utilizes an intelligent, closed-loop CC/CV charge cycle to control the charging of batteries. The device uses a constant-current mode to charge the battery in a fast and safe manner, and will then switch to the constant-voltage mode to top off the charge. The user can program the current limit, termination voltage, reset and sense pins in order to ensure that the battery is charged safely and efficiently. This PMIC features an internal voltage regulator, allowing the device to automatically adjust its output voltage to compensate for charge loss due to system components and feedback loop offsets.

The LTC1759CG#PBF is an ideal solution for applications that require reliable charging and precise control. This PMIC is extremely reliable and provides advanced, precise control over battery charging, making it suitable for a wide range of industrial and embedded applications, such as automotive and home electronics, medical and consumer devices, power tools, and portable devices. Additionally, the integrated voltage regulator, adjustable charge setting, active low reset pin, and precise current monitoring ensure that the device is always charging the battery safely and efficiently.
