LTC4076 - Dual Input Standalone Battery Charger
LTC4076 - Dual Input Standalone Battery Charger - Linear Technology（凌力尔特）
No external sense resistor or blocking diode is required for charging due to the internal MOSFET architecture. Internal thermal feedback regulates the battery charge current to maintain a constant die temperature during high power operation or high ambient temperature conditions. The ?oat voltage is ?xed at 4.2V and the charge current is programmed with an external resistor. The LTC4076 terminates the charge cycle when the charge current drops below the user programmed termination threshold after the ?nal ?oat voltage is reached. The LTC4076 can be put into shutdown mode reducing the DCIN supply current to 20μA, the USBIN supply current to 10μA, and the battery drain current to less than 2μA even with power applied to both inputs.
Other features include automatic recharge, undervoltage lockout, charge status output, power present status output to indicate the presence of wall adapter or USB power and high power/low power mode (C/5) for USB compatible applications.
