Features
Versatile Charger for NiMH/NiCd Batteries:
- The LTC4011CFE#TRPBF is designed to charge 1 to 16 NiMH or NiCd cells without requiring a microcontroller or additional firmware.It gives a wide range of battery configurations an all-inclusive charging option.
- Efficient 550kHz Synchronous PWM Controller:
- It features a 550kHz synchronous PWM current source controller, ensuring efficient charging with minimal audible noise when using ceramic capacitors.
- Advanced Charge Termination and Management:
- The LTC4011CFE#TRPBF automatically manages charging with programmable current accuracy of 5%, and supports multiple charge termination techniques, including ∆V, ∆T/∆t, and top-off charging. Moreover, it has an automated trickle precharge feature for severely depleted batteries.
- PowerPath™ Control:
- Integrated PowerPath™ control allows for efficient power management and seamless transition between power sources, enhancing system reliability.
- Battery Fault Detection and Recovery:
- In order to guarantee that the battery stays correctly charged, the IC can identify battery defects and will restart charging if the battery self-discharges following a full charge cycle.
