3 Descriptions

NU2116A is a 98.0% efficient, 6-A battery charging

solution using a switched cap architecture. This

architecture and the integrated FETs are optimized

to enable a 50% duty cycle, allowing the cable

current to be half the current delivered to the battery,

reducing the losses over the charging cable as well as

limiting the temperature rise in the application. The

dual-phase architecture reduces the input cap

requirements as well as reducing the output voltage

ripple.

Support forward 2:1 and 1:1 charge mode

Support reverse 1:2 and 1:1 discharge mode

Integrated Programmable Protection Features
