However, 1.5 ms is the maximum allowed time to ensure power up within 5.0 ms. 14.4 IC startup timing with PWRON pulled low during VIN application It is possible that PWRON is held low when VIN is applied. By default, LPM_OFF bit is reset to 0 upon crossing UVDET, therefore the PF7100 remains in the LP_Off state as described in Section 13.1.2 "LP_Off state". In this scenario, quiescent current in the LP_Off state is kept to a minimum. When PWRON goes high with LPM_OFF = 0, the PMIC startup is expected to take longer, since it has to enable most of the internal circuits and perform the self-test before starting a power up sequence. |
