8 / 28 page ADM1186 Rev. 0 | Page 8 of 28 Pin No. ADM1186-1 ADM1186-2 Mnemonic Description 12 9 DLY_EN_OUT4 Timing Input. The capacitor connected to this input sets the time delay between VIN3 coming into compliance and OUT4 being asserted high during a power-up sequence. During a power-down sequence, this input sets the time delay between OUT4 being asserted low and OUT3 being asserted low. 13 10 BLANK_DLY Timing Input. The capacitor connected to this input sets the blanking time. This is the time allowed between OUTx being asserted and VINx coming into compliance; otherwise, the SET FAULT state is entered. 14 SEQ_DONE Active High, Open-Drain Output. This output is pulled low when VCC = 1 V. When the power-up sequence is complete, SEQ_DONE is asserted high. During a power-down sequence, the pin remains asserted until the time delay set by DLY_EN_OUT1 has elapsed. When a fault occurs, this pin is asserted low. 15 11 PWRGD Active High, Open-Drain Output. This output is pulled low when VCC = 1 V. The output state of this pin is a logical AND function of the UV threshold state of the VINx pins. When the voltage on all VINx inputs exceeds 0.6 V, PWRGD is asserted. This output is driven low if the voltage on any VINx pin is below 0.6 V. 16 12 OUT4 Active High, Open-Drain Output. This output is pulled low when VCC = 1 V. During a power-up sequence, this output is asserted high after the time delay set by the capacitor on DLY_EN_OUT4 has elapsed. The output is asserted low immediately after a power- down sequence has been initiated. 17 13 OUT3 Active High, Open-Drain Output. This output is pulled low when VCC = 1 V. During a power-up sequence, this output is asserted high after the time delay set by the capacitor on DLY_EN_OUT3 has elapsed. During a power-down sequence, the output is asserted low after the time delay set by the capacitor on DLY_EN_OUT4 has elapsed. 18 14 OUT2 Active High, Open-Drain Output. This output is pulled low when VCC = 1 V. During a power-up sequence, this output is asserted high after the time delay set by the capacitor on DLY_EN_OUT2 has elapsed. During a power-down sequence, the output is asserted low after the time delay set by the capacitor on DLY_EN_OUT3 has elapsed. 19 15 OUT1 Active High, Open-Drain Output. This output is pulled low when VCC = 1 V. During a power-up sequence, this output is asserted high after the time delay set by the capacitor on DLY_EN_OUT1 has elapsed (ADM1186-1) or immediately after a rising edge on UP/DOWN (ADM1186-2). During a power-down sequence, the output is asserted low after the time delay set by the capacitor on DLY_EN_OUT2 has elapsed. 20 16 VCC Positive Supply Input Pin. The operating supply voltage range is 2.7 V to 5.5 V. |
