The LTC4013EUFD#PBF is a high-performance, low-cost single-cell Li-Ion/Li-Polymer battery charger with user-programmable charge current. The LTC4013EUFD is the ultimate solution when satisfying the needs of portable and/or battery powered applications. It is capable of fast-charging Li-Ion/Li-Polymer batteries at up to 4A while using only a single control pin. The LTC4013EUFD is an efficient, low-cost battery charger that includes a programmable charge current up to 4A, user programmable charge rate feature and a low-noise LED display.

The LTC4013EUFD features an integrated MPQ linear regulator that regulates the output voltage to a target voltage of 4.20V for Li-Ion/Li-Polymer applications. This voltage can be adjusted with a single resistor or with an external reference voltage. The MPQ linear regulator also allows adjustable output resistance for air/grade battery applications at no added cost. A built-in thermistor provides thermal protection against extreme temperature conditions.

The LTC4013EUFD can be programmed to charge at up to 4A while automatically detecting and compensating for voltage droops. An external sense resistor is used to sense the charge current, allowing accurate current regulation and temperature-dependent charge current regulation. For higher battery currents, the LTC4013EUFD has an internal low-side MOSFET, reducing turn-on time to minimize ripple current.

The LTC4013EUFD has a built-in RSW (reverse charge current) and reverse voltage protection. The device also features a programmable timer that prevents overcharging after the timer expires. The device\'s digital core also includes several safety features such as Battery Capacity/Charge Status monitoring to protect the battery from undesired conditions.

The LTC4013EUFD is ideal for applications such as power tool batteries, automotive applications, portable medical devices, consumer electronics, and other mobile applications. The device can be programmed with charge currents up to 4A to maximize charging speed without the requirement of an external gate driver. It can also be used in small form-factor applications with its low-profile DFN10 package.

In summary, the LTC4013EUFD#PBF is a single-cell Li-Ion/Li-Polymer battery charger that is designed to meet the needs of portable and/or battery powered applications. The LTC4013EUFD features an integrated MPQ linear regulator, which regulates the output voltage to a target voltage of 4.20V for Li-Ion/Li-Polymer applications. It can be programmed to charge at up to 4A while automatically detecting and compensating for voltage droops. The device also features a programmable timer that prevents overcharging after the timer expires and several safety features for the battery. The LTC4013EUFD is ideal for applications such as power tool batteries, automotive applications, portable medical devices, consumer electronics, and other mobile applications.
