... SENSE tion in the pass transistor. The charge current is deter- mined by the current limit of the input supply. LTC1730-4/LTC1730-4.2 When the battery voltage reaches the final float voltage, the pass transistor turns off for 100ms (minimum off- time). It remains off as long as the battery voltage stays above the float voltage after the 100ms off-time ...
