Product Overview


The LTC4007EGN#PBF is a 4A high efficiency standalone Li-ion Battery Charger for 3 or 4-cell lithium-ion batteries. The PWM controller uses a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors. Charging current is programmable to ±4% accuracy using a programming resistor. Charging current can also be monitored as a voltage across the programming resistor. The output float voltage is pin programmed for cell count (3/4 cells) and chemistry (4.2/4.1V). A timer, programmed by an external resistor, sets the charge termination time. Charging is automatically restarted when cell voltage falls below 3.9V/cell. If the cell voltage is less than 2.5V, a low-battery indicator asserts and can be used to program a trickle charge current to safely charge depleted batteries. The FAULT pin is also asserted and charging terminates if the low-battery condition persists for more than 1/4 of total charge time.
  • Complete charger controller for 3 or 4-cell Lithium-Ion batteries
