"Zero defects" for shipped products is always our goal.View our quality and reliability program and certifications for more information. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. The LTC4006 includes a thermistor sensor input that suspends charging if an unsafe temperature condition is detected and automatically resumes charging when the battery temperature returns to within safe limits.ĪDI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. Charging terminates if the low-battery condition persists for more than 25% of the total charge time. Charging automatically resumes when the cell voltage falls below 3.9V/cell.įully discharged cells are automatically trickle charged at 10% of the programmed current until the cell voltage exceeds 2.5V/cell.
A timer, programmed by an external resistor, sets the total charge time or is reset to 25% of total charge time after C/10 charging current is reached. Charging current can be monitored as a representative voltage at the I MON pin. Charging current is programmable with a single sense resistor to ±4% typical accuracy.
The LTC4006 is available in 8.4V, 12.6V and 16.8V versions with ☐.8% voltage accuracy. The PWM controller is a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors.
The LTC4006 is a complete constant-current/constant voltage charger controller for 2-, 3- or 4-cell lithium batteries in a small package using few external components.
