The LTC4070IDDB#TRPBF is an integrated Li-Ion/Li-Poly battery charger solution for space-constrained products such as portable electronics, consumer electronics, and digital cameras. The LTC4070IDDB#TRPBF is specifically designed to be used in low power, miniaturized applications and is small enough to occupy only a few cubic millimeters of PCB space. The LTC4070IDDB#TRPBF is a highly functional and efficient battery charger which offers adjustable charge current, battery temperature monitor, adjustable thermal control, and fault protection.The LTC4070IDDB#TRPBF is classified as a PMIC (power management integrated circuit) with battery charger technology and can be found in applications such as cellphones, portable media players, and other small, low power electronics. It is an ideal choice for low power systems where space is a critical factor, as it integrates a complete suite of features into a small package. The charger features a minimum footprint that allows it to occupy a few millimeters of PCB space, leaving a vast majority of the circuits unoccupied.The LTC4070IDDB#TRPBF features an efficient charging cycle, providing a maximum of 500mA or 2A of charge current to charge a single-cell Li-Ion/Li-Polymer battery. The adjustable charge current is selected via PA and enabled via AUTO pin. The charge cycle automatically terminates when the selected charge current is reached, or the battery is fully charged, protecting it from overcharging. The charger also has thermal protection, using a thermal switch, which turns the charger off if the temperature of the battery exceeds the programmed threshold.The LTC4070IDDB#TRPBF also provides safety features to protect the battery from over-voltage, over-temperature, and over-current charging; as well as reverse polarity protection and under-voltage lockout. A wide operating temperature range of -40℃ to 125℃ further enhances its power management capabilities. Lastly, the LTC4070IDDB#TRPBF inherently supports multi-chemistry charging, allowing for compatibility with Li-Ion, Li-Pol, NiMH and NiCd batteries.In conclusion, the LTC4070IDDB#TRPBF is a highly functional and efficient battery charger solution, combining advanced electrical and thermal protection features into a small package. It is ideal for use in space-constrained applications such as portable electronics, consumer electronics, and digital cameras. It is a perfect choice for low power systems where space is a critical factor, as it integrates a complete suite of features into a few cubic millimeters of something that would have been once a precious commodity.
