Note 2: All parameters are production tested at T_A = +25NC. Limits over the operating temperature range are guaranteed by
design.
Note 3: The MAX16126/MAX16127 power up with the external MOSFETs in off mode (V_GATE = V_SRC). The external MOSFETs turn
on t_START after the IC is powered up and all input conditions are valid.
