Product Details

Demonstration circuit 486B is a dual Smart Battery PowerPath and charger controller featuring the LTC1760. The input voltage is 12 to 20V. The charger output voltage is programmed SMBus serial interface. The maximum charge current is 4A. The demo board has been optimized to work with 2, 3 and 4- Cell Li-ion battery packs. A jumper is provided to select trip for low battery voltage (LOBAT), VLIMIT (VLIM), and ILIMIT (ILIM). The LTC1760 follows the Smart Battery Standards for the Smart Battery System Manager (SBSM) specification.
