2 / 6 page Pin Configuration TSSOP-14 10130902 Ordering Information Order Number Package Number Package Type Supplied As* LM2601MTC MTC14 TSSOP-14 Rail (94 Units/Rail) LM2601MTCX MTC14 TSSOP-14 Tape and Reel (2500 Units/Reel) * Partial Rails are available, there is no minimum order quantity. Tape and Reel is supplied as full reels only. Pin Description Pin No. Name Function 1 MPS DELAY A capacitor between this pin and ground sets the delay of the MPS risetime. See MPS DELAY description in Typical Application section. 2 MASTER POWER SOURCE Bi-directional logic pin. If driven high by an external source, indicates that a battery is powering the power bus. If driven high by the AIC, indicates the adapter is powering the bus. AIC cannot drive MPS low. If there is no valid adapter voltage present, the pin is not an output but a high impedance logic input. The input is pulled-down via an internal 40k resistor. 3 ADAPTER ENABLE Logic input pin. Active high. Grants permission to the adapter to drive both the power bus and the MPS signal. 4 ADAPTER PRESENT Logic output pin. High when 12 volts < V ADAPTER < 17 volts. The output typically has 40k pull-down resistor. The source current is not internally limited and the part can be damaged if the output is shorted to ground when driven HIGH. 5 CHARGER PRESENT Logic output pin. High when V ADAPTER > 17 volts. The output typically has 40k pull-down resistor. The source current is not internally limited and the part can be damaged if the output is shorted to ground when driven HIGH. 9 GND IC ground pin. 10 DISCONNECT Drives the gate of the disconnect P-ch FET. 11 BACKFEED Drives the gate of the backfeed P-ch FET. 12 DIRECTION SENSE Connection for current sense resistor to control BACKFEED. 13 PEAK SENSE Connection for current sense resistor to control DISCONNECT. 14 V ADAPTER Power input pin. Output of AC adapter, auto adapter or airline adapter. www.national.com 2 |
