PrE 1/02 ADM1072–SPECIFICATIONS Parameter Min Typ Max Units Test Conditions/Comments Operating Voltage Range +2.7 +5.5 Volts Quiescent Current (Total Device) 50 µA VIN = 5V, ON1,ON2 = GND, IOUT = 0A Shutdown Supply Current (Total Device) 0.01 2 µA ON1,ON2 = VIN = 5.5V, VOUT = 0V Undervoltage Lockout 2.0 2.3 2.6 V VSTBY_IN, Rising Edge, 1% Hysteresis On Resistance ? 135 m VIN = 4.75V ?? m VIN = 3.0V NOMINAL CURRENT-LIMIT Full Power Mode 0.8 1.0 1.2 A STBY Low Note 1 Standby Mode 160 200 240 mA STBY High Note 1 ON1,ON2, STBY Input Low Voltage, VIL 0.8 V VIN = 2.7V to 5.5V ON1,ON2, STBY Input High Voltage, VIH 2.4 V VIN = 2.7V to 5.5V ON1,ON2, STBY Input Leakage 0.01 ±1 µA VON, VSTBY = 5.5V FLT1,FLT2 Logic Output Low Voltage 0.4 V ISINK = 1mA FLT1,FLT2 Output High Leakage Current 0.05 1 µA VFAULT = 5.5V Turn-On Time 4 ms VIN = 5V, IOUT = 500mA 4ms VIN = 3V, IOUT = 500mA Turn-Off Time ? ? 20 µs VIN = 5V, IOUT = 500mA Notes 1Current limit is specified with V OUT = 4.5V. 2Guaranteed by design. Derived from the I SET current ratio, current-limit amplifier and internal set resistor accuraciues. 3Tested with I OUT = 200mA and VSET adjusted until (VIN - VOUT) 0.8V. 4Specifications to -40oC are guaranteed by design, not tested. (Specification for either channel 1 or channel 2, VIN = +5.0V, TA = -40 to +85 oC, unless otherwise noted.) |
