LTC1734ES6-4.2#TRMPBF

The LTC1734ES6-4.2#TRMPBF is a linear battery charger designed for use with lithium-ion batteries, often used in applications such as cell phones, laptops, PDAs, digital cameras and other portable devices. This low-cost charge controller features a constant-voltage/constant-current (CV/CC) charging algorithm and utilizes a Buck-Boost converter to maintain the charging current at a constant level.

The device accepts an input voltage ranging from 4.2V to 20V and can charge batteries ranging from 1.2V to 4.2V. The device also offers a wide operating temperature range and is capable of charging multiple battery types. The device also includes a low battery warning feature and an overcharge protection that prevents overcharging of the battery.

The LTC1734ES6-4.2#TRMPBF consists of a CV/CC charging control circuit, a high-efficiency buck-boost converter, and a battery voltage and charge current monitor. The device is designed to provide high-accuracy voltage and current regulation with minimal ripple and fast transient response. The CV/CC algorithm is designed to charge a battery as quickly and safely as possible while protecting the battery from overcharging. The overcharge protection prevents damage to the battery and limits the charging current to the maximum safe level.

The buck-boost converter is designed to provide constant current at a constant voltage, allowing the battery to charge faster and more safely. The constant current mode of the converter stabilizes the output voltage for input voltages outside the specified range, protecting the battery from overcharging. It also provides improved circuit stability and improved efficiency. The converter also offers a low-noise operation and a wide operating temperature range.

The current monitor in the device provides an accurate indication of the battery charge status and helps to ensure efficient charging. The battery voltage and charge current are monitored at regular intervals to ensure safety and accuracy of the charging process. The device also includes an overcharge clock, which prevents the battery from being overcharged for prolonged periods.

The LTC1734ES6-4.2#TRMPBF is a highly versatile device and is suitable for a wide range of applications, including cell phones, PDAs, digital cameras and other portable devices. The device is designed to provide efficient, reliable and safe charging and is ideal for applications where the battery must be charged quickly and safely. The device is also a good choice for designers looking for a low-cost, highly reliable and efficient power management solution for their applications.
