Note 1: Limits are 100% production tested at T_A = +25°C. Limits over the operating temperature range are guaranteed through
correlation using statistical quality control (SQC) methods.
Note 2: Input withstand voltage. Not designed to operate above V_DC = 6.5V due to thermal-dissipation issues.
Note 3: ISET voltage when CT timer stops. Occurs only when in constant-current mode. Translates to 20% of fast-charge current.
Note 4: Temperature at which the input current limit begins to reduce.
